Makita’s 6” SJS Cut-Off/Angle Grinder combines 13 AMP power with comfort and motor-protection features for longer-lasting industrial performance. The 9566PC is engineered with Makita’s innovative SJS™ mechanical clutch system to protect the gears for longer tool life. The 9566PC is powered by a 13 AMP motor that delivers 9,000 RPM, with soft start for smooth start-ups. Labyrinth construction protects the motor with a complex set of channels, prohibiting dust and contamination. In addition, the protective zig-zag varnish seals the motor and bearings from dust and debris by creating a barrier under rotation. (includes both cutting/grinding wheels & guards)
