Optimize your toolroom capability with this reliable K.O. Lee Model S618B Manual Precision Surface Grinder. Pictured sitting ready on its shipping pallet, these classic American-made shop mainstays (originally engineered out of Aberdeen, South Dakota) are highly prized across manufacturing environments for delivering high mechanical accuracy during demanding daily tool-and-die processes. The exact designation is a K.O. Lee Model S618B (the ""S618"" indicating the 6” × 18” capacity, and the ""B"" designating the manual hand-feed precision model class).

The addition of a Digital Readout (DRO) drastically elevates the functionality of this toolroom grinder, allowing a machinist to read cross-feed and vertical micro-movements digitally down to 0.0001” rather than squinting at the mechanical vernier dials.
