FEMOBOOK Coffee Grinder is engineered for consistent, zero-retention performance in both home and commercial settings. Its motor-shaft separation and 68 mm stainless-steel conical burr—with over 300 micro-click adjustments (0.008 mm per click)—deliver uniform grounds from espresso to pour-over. A low-speed 60 RPM motor, magnetic aluminum module, and safety-slide lock ensure smooth operation, precise control, and effortless cleanup.
