Precision Spring-Loaded & Calibrated Tamper Our 53.3mm espresso tamper features a built-in spring-loaded mechanism for consistent and level tamping every time. Prevents over or under-tamping, and is essential for even extraction and achieving that perfect espresso shot. Professional WDT tool Included This kit includes a WDT tool with 6 ultra-fine needles. It effectively breaks up clumps in your coffee grounds, promotes even distribution, and minimizes channeling for a more balanced and flavorful extraction. Say goodbye to sour or bitter shots! 53mm Puck Screen Enhance your espresso puck prep with our reusable 53mm puck screen. Placed on top of the coffee grounds before tamping, it helps distribute water evenly across the coffee bed, protects your espresso machine shower screen from grounds, and makes cleanup easier.
