Our coffee tamper fits 51mm portafilters, it is spring-loaded and requires no further adjustments. It has an ergonomic handle for a comfortable grip and allows you to easily press coffee grounds. The tamper has a solid base (51mm diameter) and is made of food-grade material. It is dishwasher safe and will not rust. Our stainless steel mixer with a threaded base gives you peace of mind when making espresso like no other. Equipped with a silicone pad and pin, the silicone pad can protect your countertop and coffee tamper from damage. It can catch coffee grounds on the tamper's base and keep your countertop clean and tidy. The pin can mix the powder more loosely and evenly. Unlike all coffee tampers on the market, ours is improved and upgraded with an attractive depth marking scale that makes it easy to set the optimal coffee extraction depth even for beginners. Just pick up and easily communicate for a smooth and perfectly brewed espresso in your own kitchen. The evenly graded tamper gives your coffee a smoother taste and better crema.
