Makita’s 5 in. SJS Angle Grinder combines 13 amp power and variable speed with comfort and motor-protection features for longer-lasting industrial performance. The motor that delivers 2,800 to 10,500 RPM, with soft start for smooth start-ups. The protective zig-zag varnish and labyrinth construction seals and protects the motor and bearings from dust and debris for longer tool life. The 9565PCV is engineered with SJS, an innovation from Makita that protects the gears by automatically disengaging the motor should the grinding wheel accidentally catch or bind. The 9565PCV weighs only 5.3 lbs. and the side handle can be easily installed on either side of the tool as well as the top. The tool-less wheel guard adjustment provides easy clamping. The large paddle switch with lock-off is designed for more comfortable operation.
