"The Gold Standard for Effortless Precision"

Available for sale is a high-performance 1997 Mitsui MSG-200MH. Renowned in the industry as the "Rolls-Royce" of manual grinders, the Mitsui MH series is famous for its signature linear ball bearing table, which provides a "weightless" feel and ultra-sensitive feedback that standard friction-way grinders cannot match.

This 1997 vintage unit is equipped with a 2-Axis Digital Readout (DRO) and a Fine-Pole Magnetic Chuck, making it a "plug-and-play" solution for high-precision mold, die, and aerospace components. Built on a heavy, ribbed Meehanite casting with hardened D2 steel ways, this machine is designed to maintain sub-tenth tolerances for decades.
