This coffee tamper fits a 51mm portafilter, is spring-loaded, and requires no further adjustment. It features an ergonomic handle for a comfortable grip and easy coffee tamping. The tamper has a robust base (51mm diameter) and is made of high-quality, food-grade material. It's dishwasher safe and rust-resistant. The stainless steel threaded base for the mixer gives you peace of mind when brewing like no other. Equipped with a silicone pad and pin, the silicone pad can protect the counter and coffee tamper from damage, catch any coffee grounds on the base, and keep the countertop clean and tidy. The pin can mix the powder more loosely and evenly. Unlike all coffee tampers on the market, ours has been improved and upgraded with an attractive deep marking scale that makes it easy to set the optimal coffee brewing depth, even for beginners. Simply scrape and spread lightly to achieve a smooth, even surface. Enjoy a perfectly brewed cup in the comfort of your kitchen. An evenly graded tamp gives your coffee more flavor and better crema.
