The tool aisle is arranged to sell you a system. A drill, an impact driver, a circular saw and a work light in one box, all running on the same battery, all from the same brand, and once you own two of them every future purchase has quietly been decided for you. That is genuinely good value if you want four tools today. It is a trap if you want one tool this month and a different one in March, which is how most households actually acquire tools. That is the test every one of these power tools you can buy one at a time has to pass.
So this roundup grades something the specification sheets never mention: what each tool commits you to after you have paid for it. Power tools you can buy one at a time are the ones that arrive complete, work straight out of the box and do not decide your next three purchases. For each of the six below we asked the same three questions — what powers it, what you must buy next, and what happens when that power source finally dies. For power tools you can buy one at a time, that is the deciding specification.
The grades disagree with the scores, which is the interesting part. The highest-scoring tool here is the only one that starts a battery platform. The second-highest is the only one whose cell cannot be replaced at all. The three that commit you to nothing are the three plainest machines on the page, and one of them costs under fifty dollars and would be our answer if you were only ever going to buy one. It is a plain point, and it is what separates power tools you can buy one at a time from a system purchase.
How the six compare at a glance
Score is the SoftPickr review score for each tool. The two columns that matter for this article are the last two: what the tool actually needs to run, and what that choice obliges you to buy afterwards. This is the sort of detail that decides which are power tools you can buy one at a time. Readers shopping for power tools you can buy one at a time should note this one.
| # | Tool | Score | Price | What powers it | The purchase it forces next | Grade |
|---|---|---|---|---|---|---|
| 1 | DEWALT DCD771C2 drill | 8.8 | $119 | Two removable 20V MAX 1.3Ah packs | A larger pack, then every future cordless tool from one brand | Brand platform |
| 2 | SKIL SD5618 screwdriver | 8.7 | $37.99 | 4V lithium cell, integrated, USB charged | Nothing — until the cell dies, and then the whole tool | Sealed cell |
| 3 | Stanley SL18116P wet/dry vacuum | 8.6 | $49.99 | 120 V mains cord | Filters and bags, and a longer hose early | Mains only |
| 4 | DEWALT DWE315K multi-tool | 8.5 | $178.99 | 120 V mains cord | Blades, continuously — the largest running cost here | Mains only |
| 5 | Westinghouse ePX3500 washer | 8.5 | $169 | 120 V mains cord | Pump antifreeze every autumn; a surface cleaner for a drive | Mains only |
| 6 | Huepar 3×360 laser level | 8.5 | $99.99 | Factory-fitted li-ion, USB-C, plus 3x AA backup | Three AA cells from any shop; a $50 detector only for outdoors | Commodity backup |
1. DEWALT DCD771C2 Cordless Drill — The best tool here, and the only one that starts a platform
Specifications: 20V MAX lithium-ion · 2-speed, up to 1,500 rpm · 1/2 in (13 mm) single-sleeve ratcheting chuck · 30 mm wood, 13 mm metal capacity · two 1.3Ah packs, charger and contractor bag · 3.6 lb bare · 3-year limited warranty · 49,705 ratings at 4.8 stars · $119 · SoftPickr score 8.8/10 · grade Brand platform.
This is the drill people are told to buy when they ask, and 49,705 ratings averaging 4.8 stars suggest the crowd has it right. A rating that high across a base that large is not a measure of how good a tool is at its best; it is a measure of how rarely it disappoints, which is the more useful figure for something you expect to own for a decade. Buyers looking for power tools you can buy one at a time should weigh that carefully. That single fact is why power tools you can buy one at a time are worth thinking about separately.
The specification doing the work is the two-speed transmission: a low, high-torque range for driving long screws and boring large holes without stalling, and a high range topping out at 1,500 rpm for pilot holes where speed does the cutting. On this page, power tools you can buy one at a time are graded on exactly that question. Seen as one of the power tools you can buy one at a time, the trade is a fair one.
The chuck is the part you touch most and it is a 1/2 inch single-sleeve ratcheting design, which means you tighten it one-handed while the other hand holds the work, and the bit does not creep loose under load. The half-inch capacity accepts the larger shanks on spade bits and hole saws rather than topping out at 3/8 inch, and with 30 mm wood and 13 mm metal capacity that covers essentially every household job short of masonry. There is no hammer function, so masonry is not on the list at all. It is a useful reminder of why power tools you can buy one at a time are worth identifying.
Then the commitment. Any 20V MAX battery fits this drill and DEWALT sells a very large range of tools on the same pack, so the two cells in the box are the start of a system rather than a dead end. That is the selling point and the catch in one sentence. The included packs are 1.3Ah, which is small — roughly twenty to thirty minutes of continuous driving each — and our full review describes a larger 4.0Ah or 5.0Ah pack as a sixty-dollar problem attached to a one-hundred-and-nineteen-dollar kit. Buy this and your next cordless purchase has largely been decided for you.
One honesty note about the listing: it reports two different maximum torque figures, 650 in-lb in one field and 530 in-lb in another, which is roughly 73 Nm against 60 Nm. DEWALT normally quotes this tool in unit watts out rather than inch-pounds, so treat any single torque number here as indicative rather than measured. The motor is brushed rather than brushless, which is the usual trade at this money: a brushless drill of similar price generally ships bare or with one small battery and no bag. That reasoning is what puts it among power tools you can buy one at a time rather than in a kit.
Best for: the first drill in a household that owns none, where a two-speed gearbox, a proper ratcheting chuck and a three-year warranty matter more than the platform question.
Skip if: you drill masonry, because there is no hammer function and no way to add one — or you already own a cordless platform from another brand, in which case a bare tool on the batteries you have is cheaper than starting a second ecosystem here.

Anyone hunting for power tools you can buy one at a time will recognise the pattern. It is the kind of compromise power tools you can buy one at a time tend to carry.
2. SKIL 4V Cordless Screwdriver — The best-scoped tool on the page, on a clock
Specifications: Model SD5618-03 · 4V lithium-ion, integrated · USB charging, cable included · 36 in-lb (about 4 Nm) · 220 rpm no-load · 1/4 in hex magnetic chuck · pivoting in-line or pistol grip · 42-piece bit set · cam screw sleeve · LED at the nose · about 2.5 lb as shipped with the case · 4.8 stars from 2,500-plus ratings · $37.99 · SoftPickr score 8.7/10 · grade Sealed cell.
There is a gap in most households between a manual screwdriver, which is slow and hard on the wrist, and a cordless drill, which is heavy, loud and far too powerful for a cabinet hinge. This is built squarely for that gap. Thirty-six inch-pounds will drive a 1-1/4 inch screw into softwood, run a full set of cabinet hinges, take apart and reassemble flat-pack furniture, fit a curtain rail into a wall plug and handle switch plates all day. The distinction matters most to people buying power tools you can buy one at a time.
It carries the highest customer rating of anything in its review round at 4.8 stars, which usually means a product is very clearly scoped and buyers got exactly what they expected. Judged as one of the power tools you can buy one at a time, it holds up well. The whole case for power tools you can buy one at a time rests on points like this.
Two design details earn their place. The handle rotates between a straight in-line position and a pistol position and locks firmly at both rather than wobbling in between, which matters because in-line is what reaches inside a cabinet and pistol is what lets you put your forearm behind the bit. The cam screw sleeve slips over the bit and limits engagement so you can run flat-pack cam locks under power without stripping the particleboard, which is a small piece of plastic that will save you an hour on a wardrobe. That is the arithmetic behind power tools you can buy one at a time.
Now the power source, which cuts both ways. It charges over standard USB from any phone charger, laptop or power bank, so there is no proprietary battery brick to lose and nothing to plan around. But the 4V cell is integrated, not removable. When it eventually stops holding charge the tool is finished: there is no user-replaceable pack and no sensible repair path at this price, so its life is measured in charge cycles rather than in mechanical wear. For a household using it a few times a month that is years away and a fair trade.
For anyone using it daily it is the wrong tool, and the removable-battery 12V class is where you should be shopping. It is a good illustration of what power tools you can buy one at a time look like in practice. Among power tools you can buy one at a time, that counts as a genuine advantage.
The other limit is simply power, and the pistol-grip silhouette invites the wrong expectations. There is no drill chuck and no hammer function, and 220 rpm at 36 inch-pounds will stall on hardwood, lag screws, deck boards and masonry. That slow speed is deliberate rather than cheap — it gives control and stops the bit camming out and chewing a screw head — but it means this is a powered screwdriver and not a small drill, and buying it as one ends in frustration. For power tools you can buy one at a time, that is the deciding specification.
Best for: flat-pack furniture, hinges, handles, switch plates and curtain rails — indoor fasteners, several times a month, with a complete 42-bit kit in a case.
Skip if: you use a screwdriver daily for work, because the integrated cell has no replacement path at all — or your list includes decking, masonry or long screws into oak, where 36 inch-pounds will stall and you will finish by hand.

Readers shopping for power tools you can buy one at a time should note this one. That is one more reason to think in terms of power tools you can buy one at a time.
3. Stanley SL18116P Wet/Dry Vacuum — The best of the power tools you can buy one at a time
Specifications: 6 US gallons (22.7 L) · 4 peak HP, 1,200 W, 3.7 A · 85 in water lift · stainless steel drum · converts to a blower · 6 ft hose · 80 dB · four castors · 13.4 lb · 1-year limited warranty · 14,309 ratings at 4.6 stars · $49.99 · SoftPickr score 8.6/10 · grade Mains only.
Two numbers describe what a wet/dry vacuum can do, and horsepower is not one of them. Drum size is the first: six gallons is the domestic sweet spot, big enough to take a flooded utility room floor without three trips to the drain and small enough that a full drum is still liftable by one person. Water lift is the second and the more meaningful, because it is the vacuum’s ability to pull a heavy object up a hose. At 85 inches this sits in genuine shop vacuum territory rather than in the upgraded-household-vacuum territory some competitors occupy.
The drum is stainless rather than moulded plastic, and that is the decision that separates it from the price-band competition. Plastic drums crack, not immediately but after a couple of winters in an unheated garage and enough knocks against a workbench leg. Stainless does neither, though it dents permanently where plastic would flex back, which is cosmetic rather than functional. Move the hose to the exhaust port and the machine becomes a blower for leaves, sawdust and a wet car, which is a genuine second tool at no extra cost. That single fact is why power tools you can buy one at a time are worth thinking about separately.
On this article’s axis it is the plainest machine here and that is the point. A mains cord and nothing else: no cell to age out, no platform to join, no charger to lose. The recurring costs are filters and bags, and the one thing to get right is the changeover — foam sleeve with no bag for wet pick-up, the reusable cartridge for general dry work, cartridge plus a bag for fine dust. Vacuuming water with the dry cartridge fitted soaks and destroys it, and that failure is not a warranty claim. Anybody assembling a kit from power tools you can buy one at a time will meet this question.
The compromises are noise and reach. It runs at 80 decibels with no quiet mode and no variable speed, because the motor is a single-speed unit, and the six-foot hose is short enough that a longer one is among the most commonly bought accessories for this model. The supplied foam filter is not a fine-dust solution either: drywall, plaster and cement dust pass straight through it, so those jobs need the cartridge plus a bag, and even then this is not a HEPA machine at any filter setting. Seen as one of the power tools you can buy one at a time, the trade is a fair one.
Best for: the single best first purchase on this page — under fifty dollars, commits you to nothing, and handles sawdust, gravel, broken glass and standing water that a household vacuum cannot.
Skip if: noise is a real constraint, because 80 decibels with no quiet mode is loud enough to want ear defenders — or you do regular drywall, plaster or cement dust without budgeting for a finer filter.
Read the full Stanley wet dry vacuum review for the complete specification table, the eight-point scoring breakdown and the full list of pros and cons. It is the kind of compromise power tools you can buy one at a time tend to carry. It is exactly the sort of thing power tools you can buy one at a time should be checked for.
4. DEWALT DWE315K Oscillating Multi-Tool — Superb, corded, and hard to justify
Specifications: 3.0 amp corded, 120 V · up to 22,000 OPM · variable speed · quick-change arbor, no hex key · integrated LED · wood blades, sandpaper and tool bag included · 3-year limited manufacturer warranty · 4.8 stars from 2,695 ratings · $178.99 · SoftPickr score 8.5/10 · grade Mains only.
An oscillating multi-tool is the thing you reach for when no other tool can get there. It cuts flush against a surface, plunges into the middle of a board without a pilot hole, undercuts a door jamb so flooring slides beneath, grinds grout out of a joint and sands into corners. Every one of those jobs is either impossible or ugly with anything else, which is why the category exists at all rather than being a novelty. The whole case for power tools you can buy one at a time rests on points like this.
Three amps is a mid-to-upper motor rating for a corded multi-tool, and the number that matters alongside it is how well the tool holds that speed under load. Cheap multi-tools bog down the moment a blade meets a nail or a hardwood stud. Variable speed matters just as much: 22,000 oscillations per minute is the top of the range and is not where most work happens, because grout, plastic and anything that melts want a much lower setting. A single-speed tool forces the fastest setting on every material, which is how people burn blades. Among power tools you can buy one at a time, that counts as a genuine advantage.
Corded is the right choice for this particular category and it is worth saying why. Multi-tools are used for short, awkward, high-precision cuts in confined spaces where a battery pack adds bulk exactly where you need clearance, and they draw hard enough to flatten a small pack quickly. A cord means constant power and a lighter tool at the working end. It also means an extension lead in a loft or under a floor, which is a genuine daily annoyance rather than a theoretical one. That is one more reason to think in terms of power tools you can buy one at a time.
The catch is price, and the listing is careless in two places. Corded multi-tools from established brands in the same search sat at roughly a quarter to a third of this figure, several with variable speed and larger accessory kits, and they will do the great majority of what this one does. The listing also gives item weight as 0.34 kilograms, about twelve ounces, which is not plausible for a three-amp corded tool with a metal gear head, and quotes kit dimensions for the packaged bag rather than the tool. Neither error affects the product; both mean the specification sheet cannot be read literally.
Best for: somebody who uses a multi-tool regularly rather than twice a year, already owns corded tools, and wants variable speed and a three-year warranty on a tool used in demolition conditions.
Skip if: this is a DIY tool you will use a handful of times a year — our own review says plainly that most readers should buy something cheaper — or you already own a battery platform, where a bare cordless multi-tool is cheaper and better in a loft.

Anybody assembling a kit from power tools you can buy one at a time will meet this question. For a household buying power tools you can buy one at a time, that is the practical consequence.
5. Westinghouse ePX3500 Pressure Washer — The one that publishes its real numbers
Specifications: 2,500 max PSI (172 bar), 2,000 rated PSI (138 bar) · 1.76 max GPM (6.7 L/min), 1.2 rated GPM (4.5 L/min) · five quick-connect nozzles · pro-style steel wand · 25 ft hose · 20 fl oz onboard detergent tank · Total Stop System · 16.5 in tall, 19 lb, four-wheel steering · 3-year limited warranty · 13,487 ratings at 4.6 stars · $169 · SoftPickr score 8.5/10 · grade Mains only.
Pressure washers are sold on a single number and it is the wrong number. Maximum PSI is measured at the nozzle at the instant the trigger closes and flow stops; maximum GPM is measured at zero pressure. Neither condition is one in which any cleaning is happening. Westinghouse quotes 2,500 maximum PSI and 1.76 maximum GPM and then quotes 2,000 rated PSI and 1.2 rated GPM in the same description, which is more transparency than most of the category offers and is the reason this machine is here. It is exactly the sort of thing power tools you can buy one at a time should be checked for.
The useful comparison is cleaning units, which is pressure multiplied by flow. At its rated figures this produces 2,400 cleaning units: comfortably enough for cars, patios, fences, garden furniture and siding, and not enough to strip paint or clear commercial concrete quickly. Anyone comparing this against a 3,000 PSI machine on headline numbers alone is comparing two figures neither of which describes cleaning. A surface cleaner attachment roughly triples driveway speed and is not included. For a household buying power tools you can buy one at a time, that is the practical consequence. This is where power tools you can buy one at a time differ most from a four-tool combo box.
The chassis is the genuine innovation. Almost everyone who has used an electric pressure washer has spent part of the session walking back to pick it up, because the standard tall two-wheeled form factor tips over whenever the hose goes taut. This one is 16.5 inches tall with a low centre of gravity and four steering wheels, so it follows you rather than resisting you, and at 19 pounds it stores on a shelf. The Total Stop System shuts the motor down on trigger release rather than letting the pump cycle against a closed valve, which is the single most important longevity feature on any electric machine.
Its power arrangement is a mains cord, so there is no cell and no platform, but there is one recurring seasonal commitment that people skip and regret. Before the first frost the hose and pump have to be drained and pump antifreeze run through the inlet, because water left in the pump housing over a hard winter will crack it and that failure is not covered by the three-year warranty. The wear points are where you would expect at this money: plastic inlet fittings, a plastic trigger gun, and reports of O-rings weeping after a season.
Best for: a household with a patio, a drive, some fencing and a couple of cars, and limited storage space for a machine that lives indoors between jobs.
Skip if: you are cleaning large expanses of commercial concrete or stripping paint, where a petrol machine is the honest answer — or your only outdoor tap is a long way from any socket, since 25 feet of hose plus the cord is a tight radius.

6. Huepar 3×360 Green Laser Level — The smartest power arrangement on the page
Specifications: 3×360-degree green beams, one horizontal and two vertical · 532 nm · accuracy ±1/9 in at 30 ft (±3 mm at 10 m) · 65 ft unaided, 200 ft with detector · ±4-degree self-levelling · pulse mode · 1/4-20 and 5/8-11 threads · li-ion via USB-C, 8-hour runtime · 3x AA backup compartment · IP54 · 2-year registered warranty · 4.6 stars from 2,447 ratings · $99.99 · SoftPickr score 8.5/10 · grade Commodity backup.
A cross-line laser gives one horizontal and one vertical reference at the wall you are pointing at. This gives a horizontal plane that circles the entire room and two perpendicular vertical planes that run floor to ceiling all the way around. In a kitchen cabinet install that means the wall-cabinet reference line is visible on all four walls at once without repositioning the tool, and on a tile floor it means one setup gives the same height around every wall. The point generalises to all power tools you can buy one at a time.
Green diodes at 532 nm are roughly four times more visible to the human eye than red diodes at the same output, which in practice is the difference between a line you can see across a normally lit room and one you have to dim the lights for. Unaided indoor range is about 65 feet against roughly 30 feet for a red cross-line. Green diodes are less efficient, which is exactly why rechargeable batteries became standard on green lasers and why the power arrangement on this one is worth examining. It is a small detail, and it matters to power tools you can buy one at a time.
It has the best power design here and it is not the most expensive tool on the page. The primary cell is a factory-fitted lithium-ion charged over USB-C, rated at eight hours of continuous three-line operation. When that is flat and there is no socket, a compartment takes three AA alkaline cells from any convenience store and the tool goes straight back to work. That single compartment eliminates the flat-battery failure mode that rechargeable-only rivals still have, and it costs the manufacturer almost nothing. As power tools you can buy one at a time go, this one is unusually honest about its limits.
It also hedges the tool’s own weakness, because the lithium cell is factory-fitted and replacing it means a service return to Huepar rather than a part you buy. The other limits are honest ones: the unaided 65-foot range collapses to about 15 feet in direct sunlight, so outdoor work needs the separately sold LR6RG detector at fifty dollars; accuracy of one-ninth of an inch at 30 feet is finish-carpentry rather than surveying grade; self-levelling refuses beyond four degrees; and the anti-reflective diode window strips with solvent, so it is dry microfibre only. That is the shape of the decision behind power tools you can buy one at a time.
Best for: cabinet, tile and framing layout where one setup should give a reference on all four walls, and where a flat battery on a Saturday must not end the job.
Skip if: your main use is outdoor framing in bright sun and you will not budget the fifty-dollar detector — or you need surveying accuracy, which means a rotary laser rather than a cross-line tool of any price.

Buyer’s guide: how to read the power source before you read the price
The rest of this page is the reasoning behind the grade column, including the two places where the rules are genuinely different in the United States and the United Kingdom, and one place where they are different within the United Kingdom. It is why power tools you can buy one at a time are worth a separate list at all.
The four power sources, and what each one costs you later
Mains only. A cord and a socket, and no second purchase attached to the power itself. The Stanley vacuum, the DEWALT multi-tool and the Westinghouse washer are all in this group. It is the least fashionable arrangement in 2026 and the one with the longest tail: there is no cell to age out, no charger to lose and no brand decision buried in the box. The running costs move to accessories instead — filters and bags on the vacuum, blades on the multi-tool, pump antifreeze on the washer.
Commodity backup. A rechargeable primary cell with a compartment that takes cells any shop sells. Only the Huepar does this, using three AA alkalines as a fallback behind its USB-C lithium pack. It is the arrangement that fails least badly, because the worst case is a two-minute trip rather than a dead Saturday, and it costs the manufacturer almost nothing to include.
Brand platform. A removable pack that fits a large family of tools from one manufacturer. The DEWALT drill is the example. Batteries stay available for years, which is a real advantage over a sealed cell, but the arrangement works by making your next purchase cheaper on one brand and more expensive on every other. That is not a defect. It is simply a commitment, and it should be made deliberately rather than discovered in month four.
Sealed cell. An integrated battery with no user-replaceable pack and no repair path at the price. The SKIL screwdriver is the example, and its own listing is candid about it. The tool’s life is counted in charge cycles rather than mechanical wear, which for a few uses a month is years away and for daily use is the wrong purchase entirely.
The battery rules are different in Belfast, Birmingham and Boston
The most useful thing a buyer can know about sealed cells is that the law is about to move, and that it is about to move in one part of the United Kingdom and not the other. Article 11 of EU Regulation 2023/1542, the EU Batteries Regulation, requires that portable batteries incorporated in products be readily removable and replaceable by the end user using commercially available tools, and that manufacturers supply spare batteries for at least five years after the last unit of a model is placed on the market. That requirement comes into force on 18 February 2027.
The UK government’s own guidance is explicit about where it lands. The EU Batteries Regulation has applied directly in Northern Ireland since 18 February 2024 by virtue of the Windsor Framework, while Great Britain continues to operate under the Batteries and Accumulators (Placing on the Market) Regulations 2008, which implemented the older 2006 Directive. The guidance confirms that the Article 11 removability requirement comes into force on 18 February 2027 and replaces the existing readily removable wording at that point, and notes that a UK-wide aligned regime is a matter for future consultation rather than settled law.
Read that against this page and the consequence is concrete. A sealed-cell tool sold in Belfast will be running against a legal clock from February 2027. The same tool sold in Birmingham will not, and the same tool sold in Boston will not either, because the United States has no federal equivalent at all. None of these six models is sold into Britain in this exact form, so this is not a warning about these SKUs; it is a statement about the direction the category is being built in, and about which of your two nearest markets will get the benefit first.
Voltage, site power and the 110 V tools Americans never see
Every corded machine here is a 120 V North American appliance. Plugging one into a 230 V British socket without a step-up transformer destroys it, so the three mains-only picks are effectively US-market products regardless of what the shipping page says. That is the boring half of the difference. The interesting half is that the British mains question is not the same question at all. Anyone who prefers power tools you can buy one at a time will read that as a plus.
The Health and Safety Executive’s guidance on electrical systems in construction recommends cordless tools or equipment running from a 110 V centre-tapped-to-earth supply, so that the maximum voltage to earth does not exceed 55 V, and it states plainly that tools, plugs and cables designed for DIY and domestic use are not suitable for site conditions. Where mains voltage has to be used it expects RCD protection together with a formal regime: visual inspection every shift and weekly, and a combined inspection and test before first use on site and monthly afterwards. The lesson applies well beyond power tools you can buy one at a time.
That is why British tool ranges carry a yellow 110 V variant with no American equivalent, and why an ordinary domestic corded tool is a perfectly sensible garage purchase in Britain and the wrong thing to carry onto a building site there. An American reader will never meet a site transformer. A British reader buying the same category of tool is choosing between two mains voltages before choosing between brands, which is a decision that simply does not exist on one side of the Atlantic. That is the sort of trade power tools you can buy one at a time ask you to make.
The numbers that do not translate, and the words that do not either
Units first, because two of them are actively misleading. The Stanley’s six gallons is six US gallons, which is 22.7 litres and not the 27.3 litres a British reader assumes from an imperial gallon — a twenty per cent error in the headline capacity. The Westinghouse’s 2,500 maximum PSI is about 172 bar and its 2,000 rated PSI about 138 bar, and British listings quote bar. Flow of 1.76 GPM is 6.7 litres per minute and the rated 1.2 GPM is 4.5. On torque, 650 in-lb is roughly 73 Nm and 36 in-lb roughly 4 Nm, and a 1/2 inch chuck is a 13 mm chuck.
Vocabulary matters most when you are searching rather than reading. A shop vac is a wet and dry vacuum in Britain and searching the American term returns almost nothing useful on a British retailer. An outlet is a socket, a power cord is a mains lead, an extension cord is an extension lead, drywall is plasterboard, a baseboard is a skirting board, a wrench is a spanner, and renting a tool for the weekend is hiring one. Getting the noun wrong is how a British reader concludes a product does not exist. In a list of power tools you can buy one at a time, that detail carries real weight.
One number deserves a calibrated benchmark rather than an adjective. The Stanley is rated at 80 decibels, and the UK Control of Noise at Work Regulations 2005 put the lower exposure action value at exactly 80 dB(A), the level at which an employer must assess the risk and provide information and training. The upper action value is 85 dB(A), where hearing protection and hearing protection zones become mandatory, and 87 dB(A) is the exposure limit value that must not be exceeded. It is one of the clearer arguments for power tools you can buy one at a time.
A homeowner is not an employee and none of this binds a garage, but it is the only publicly calibrated scale for what that 80 dB figure actually means. For anyone building up power tools you can buy one at a time slowly, this is the thing to check.
What we deliberately did not put a number on
Three figures a roundup like this is expected to supply are missing on purpose. We have not published a price for a replacement 20V MAX battery, because we found no manufacturer figure we could verify this run; our own DEWALT drill review describes a larger pack as a sixty-dollar problem attached to a one-hundred-and-nineteen-dollar kit, and that is presented here as this site’s estimate rather than as a published price. We have not estimated how many charge cycles the SKIL’s sealed cell has in it, because nobody publishes that. That is what buying power tools you can buy one at a time actually looks like.
And we have not priced a Huepar replacement cell, because the route is a service return rather than a part number. It puts this firmly among power tools you can buy one at a time rather than among platform tools.
There is also no lifespan-in-years estimate anywhere in this article, for any of the six, because no honest average exists for tools whose life depends almost entirely on how hard they are worked. One more absence is worth naming and it is not ours. Our review of the KAIWEETS HT118A multimeter, a tool whose whole relevance to this page is what cell it takes, records a specification sheet that says battery powered, battery included and never once names the battery. On a meter that is a specification, and it is simply missing. The same reasoning applies to the other power tools you can buy one at a time here.
Which of these should you buy?
If you are buying one tool this month and nothing else, buy the Stanley SL18116P at $49.99. It is the cheapest thing on the page, it commits you to nothing beyond filters, and it does a job no household vacuum can do. That is an unusual recommendation for a roundup to make about its third-placed entry, and it follows directly from the axis this article is graded on. That is a fair summary of the case for power tools you can buy one at a time.
If you are buying your first drill, buy the DEWALT DCD771C2 — and understand that you are choosing a battery platform at the same time, which is a decision worth making with your eyes open rather than discovering when you price your second cordless tool. If flat-pack furniture is the actual problem, the SKIL screwdriver is better at that specific job than any drill and costs a third as much, provided you accept that its cell has no replacement path. Anyone who values power tools you can buy one at a time should weigh this against the price.
If the job involves layout — cabinets, tiling, framing — the Huepar is the one we would buy, and it is joint-lowest on score. That is the clearest case on this page of the grading disagreeing with the ranking, and we think the grading is right: a tool that can run on three AA cells from a corner shop will not lose you a Saturday. It is the practical difference between power tools you can buy one at a time and a system.
The two we would not start with are the DEWALT DWE315K, whose own SoftPickr review says most readers should buy something cheaper unless they are using a multi-tool weekly, and the Westinghouse ePX3500, which is a well-judged machine that only earns its money if you genuinely have a drive, fencing and cars to keep clean. That is why this sits where it does among power tools you can buy one at a time.
Read down the score column and the DEWALT drill wins. Read down the grade column and it is fourth, because it is the only pick that decides your next three purchases for you. Both readings are honest, and the second one is the reason this article exists. For buyers of power tools you can buy one at a time, the answer is rarely the headline number.
Frequently asked questions
Is a corded tool really better than a cordless one in 2026?
Not better, but freer. A corded tool has no cell to age out, no charger to lose and no brand decision buried in the box, which is why the three mains-only picks here carry no commitment beyond accessories. Cordless wins anywhere without a socket, and for a drill that is most places. The point is to notice which purchase you are making. It is worth remembering when you compare power tools you can buy one at a time side by side.
What is wrong with buying into a battery platform?
Nothing, provided you do it deliberately. A platform makes every future tool from one brand cheaper and every tool from any other brand effectively more expensive, and that is a reasonable trade if you expect to own five cordless tools. It is a poor trade if you expect to own one, which is the case in most households. That question is the whole reason power tools you can buy one at a time are treated separately here.
Which of these six is the best single purchase?
The Stanley wet/dry vacuum at $49.99. It is the cheapest tool on the page, it needs nothing but a socket, and it covers sawdust, gravel, broken glass and standing water, none of which a household vacuum will touch. Our full review scores it 8.6/10. That is the test every one of these power tools you can buy one at a time has to pass.
Why does the SKIL screwdriver score higher than tools that cost five times as much?
Because the score measures how well a tool does the job it claims, not how much it does. The SKIL is very tightly scoped to indoor fasteners and does all of them well, which is also why it holds 4.8 stars across more than 2,500 ratings. Its sealed cell is a real limitation and it is graded here for exactly that. It is a plain point, and it is what separates power tools you can buy one at a time from a system purchase.
Can I use any of these tools in the UK?
Not as sold. All six are 120 V North American models and a 230 V British socket will destroy the corded ones without a step-up transformer. British buyers should look for the local variant of the same category, and on a building site should be looking at 110 V centre-tapped-to-earth equipment rather than domestic tools at all. This is the sort of detail that decides which are power tools you can buy one at a time.
What does the 2027 EU battery rule actually change?
From 18 February 2027, portable batteries built into products sold in the EU must be readily removable and replaceable by the end user with commercially available tools, with spares available for at least five years after the last unit of the model ships. It applies in Northern Ireland through the Windsor Framework and does not apply in Great Britain or the United States. Buyers looking for power tools you can buy one at a time should weigh that carefully.
How loud is 80 decibels in practice?
It is roughly a passing lorry, and it is the exact level the UK Control of Noise at Work Regulations 2005 set as the lower exposure action value for employers. A five-minute cleanup is fine. An hour of workshop tidying is worth ear defenders, and there is no quiet mode or variable speed on this machine to help. On this page, power tools you can buy one at a time are graded on exactly that question.
Do I need the separate detector for the Huepar laser?
Only for outdoors. The unaided 65-foot range collapses to about 15 feet in direct sunlight, so any outdoor framing or deck work needs the LR6RG detector at fifty dollars. Indoors the green beams are visible without any accessory, and the included enhancement glasses add roughly thirty per cent to visible range. It is a useful reminder of why power tools you can buy one at a time are worth identifying.
Why is the pressure washer quoted at two different pressures?
Because two different things are being measured. The 2,500 PSI maximum is taken at the instant the trigger closes and water stops moving; the 2,000 PSI rated figure is what the pump delivers while you are actually cleaning. Westinghouse publishing both is unusually transparent, and the rated pair is the one to compare across machines. That reasoning is what puts it among power tools you can buy one at a time rather than in a kit.
What should I buy if I want a tool with nothing to power at all?
A hand tool set. Our review of the CRAFTSMAN CMMT45306 230-piece set at $129 covers the only category on this site with no cell, no cord and no charger, and its three drive sizes and VERSASTACK case mean it ages better than the kits it competes with. It is the logical end point of the argument this page makes. Anyone hunting for power tools you can buy one at a time will recognise the pattern.
Final thoughts
Nothing on this page is a bad tool. Five of the six hold 4.6 stars or better across large rating bases, and the sixth holds 4.8 across a smaller one. What separates them is not quality but obligation, and obligation is the thing no specification sheet prints and no star rating measures. The distinction matters most to people buying power tools you can buy one at a time.
If you take one habit away from this, make it the question we asked six times above: when this stops working, what exactly do I buy? If the answer is a socket, you are free. If it is three AA cells, you are nearly free. If it is a pack from one manufacturer, you have joined something. And if the answer is a whole new tool, you have bought a consumable with a handle on it — which is sometimes exactly the right purchase, as long as you knew. Judged as one of the power tools you can buy one at a time, it holds up well.
Prices and stock move around far more than specifications do, so check the current listing before ordering anything here. Every figure quoted above comes from the SoftPickr review of that product or from the manufacturer’s own published material, and where we could not verify a number we have said so rather than estimated it. That is the arithmetic behind power tools you can buy one at a time.
If your list is closer to a dripping tap and a loose hinge than to a weekend job, our companion roundup of tools for small home repairs covers the hand-tool end of the same problem, and every tool in it has no power source to grade at all. It is a good illustration of what power tools you can buy one at a time look like in practice.
