SKU bb-G5847B-OS

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.

It uses 72 built-in magnets to align and lock into place for secure and stable use during grinding and sifting.

Review and Coffee Parts Thoughts

The Blade R3 is one of the most impressive releases from MHW-3BOMBER. The combination of three-bearing support, burr geometry, and external precision adjustment is well suited to baristas looking to fine-tune their espresso or dial in clarity for filter. The included sieve system genuinely improves particle control, helping reduce fines and boosting flavour clarity, similar to what you'd find in grinders, which cost significantly more.
