An Upgrade for 51 mm Machines
The De’Longhi Dedica EC680M ships with a 51 mm portafilter and a combination plastic tamper and scoop. The K COOL swaps that for a stainless base and a spring, for about the price of a bag of coffee.
Lighter Spring
K COOL quotes approx. 8 kg of force, which is about 17.6 lb. That is lighter than the 30 lb springs on the IKAPE and MHW-3BOMBER. Most modern advice says a firm, level tamp matters more than hitting exactly 30 lb, and a lighter spring suits the pressurized baskets that 51 mm machines usually ship with.
Sizes
K COOL sells 51, 53 and 58 mm versions and says a 53 or 54 mm portafilter needs the 53 mm one. This review covers the 51 mm listing.
Limitations and Compromises
At 4.3 stars it is the lowest-rated tamper in this roundup, and its 463 ratings are the fewest. The spring force is lighter than the others. The listing does not describe a leveling collar, and some of its wording is unclear (it mentions “three flat tamping sides” without explaining them), so we relied only on the clear specifications.
Who Should Buy It?
- You own a 51 mm machine such as the De’Longhi Dedica
- You want to replace a plastic stock tamper cheaply
- You use pressurized baskets
- You want a spring tamper for $12
Skip it if you have a 58 mm machine and want the best consistency; spend more on the Normcore V4.
SoftPickr Verdict
The K COOL scores 7.8/10. It is the cheapest way to a calibrated, stainless steel tamp on a 51 mm machine, at $12.00 when we checked. Prices on Amazon move; the live listing is the only accurate source. See how it compares with six other tampers in our best espresso tamper guide.
