TOKIWA 4-14 mm End Mill Sharpener

The TOKIWA MR-X1 is a compact, portable sharpening machine that restores carbide and HSS end mills to factory-sharp precision, making worn cutting tools reusable again. Designed for end mills ranging from 4 to 14 mm in diameter with 2, 3, or 4 flutes, it helps workshops significantly cut tooling costs by reducing the need to purchase new end mills. Equipped with a diamond (SDC/CBN) grinding wheel suited to carbide (tungsten steel) tooling, the machine can grind all of the critical cutting geometries on an end mill with a single setup — including the bottom cutting edge, first and second relief angles, the core (center) angle, and the center slot. Operating at 4400 RPM, it delivers a fast and efficient sharpening process, while the easy-to-adjust clamping system makes the machine simple to operate without advanced technical training. Its rugged metal housing and built-in carry handle make the MR-X1 easy to move around, making it a solid investment for both small workshops and larger manufacturing facilities. Its compact footprint also means it fits comfortably even in limited workspace.
