Water-cooled grinder puts the finest edges on knives and other cutting tools. The grinding wheel of our Utility Sharpener spins at a slow 140 rpm through a water bath which washes away ground particles and prevents the destructive overheating of steel cutting tool edges by keeping them cool. Twin tool rests and reversible motor accommodate a wide range of grinding angles. Rubber feet maximize stability and reduce vibration, making this the quietest and smoothest running grinder we've seen. Runs on 220v/1ph. Wheel size: 118mm dia. x 38mm wide, 120 grit.
