MHW-3Bomber Blade R3 Hand Grinder 40mm Burr: Black

MHW Blade R3 Manual Coffee Grinder: Black combines high-speed grinding with fine-tuned control, offering precision burr engineering and a built-in sifter for optimal extraction results across espresso and filter brews.

Fast, Precise and Versatile Grinding for Every Method

The Blade R3 Manual Grinder by MHW-3BOMBER is engineered for consistency and speed, featuring a custom Rapidity-3 burr and a numerical external grind adjustment dial. Its 3-bearing axis ensures stable alignment, while the magnetic powder bin and included sieves simplify workflow and enhance particle distribution.

How the MHW Blade R3 Grinder Works

The grinder uses a precision external adjustment ring with 60 steps per turn (approx. 0.016mm/step) for brewing flexibility. Inside, the 48mm burr system combines a 45° 7-core blade for speed and a 70° diamond-shaped edge for uniformity. Magnetic locking and a 5-screen sifter help separate fines post-grind, improving clarity in the cup.
