WATER-COOLING is acknowledged by professionals to hone the finest edges. This compact system uses a controlled flow of water to eliminate over-heating of the blade edge & lose of temper in the steel. Simply fill the built-in reservoir with water turn on the power drill & a continuous film of water covers the face of the grinding wheel.WOOD CHISELS / PLANE BLADESThe system re-sharpens even badly damaged chisels / plane blades quickly, because it uses the relatively high power / torque of an electric drill. The clamp firmly holds the blade at the selected angle for a precision ground edge. The traditional leather strop removes any burr, for a razor sharp edge.SMALL TOOLSThe Tool Rest gives a firm base for re-sharpening, re-pointing & re-edging a whole range of small tools including: cold chisels, bradawls, screwdrivers, centre-punches, scribers, wood carving / turning tools, gouges etc. Marked angles on the Rest indicates the tip angle. Blade capacity 10-60 mm wide.
