Makita's 5 in SJS™ angle grinder combines 13 A variable speed power with comfort and motor-protection features for longer-lasting stone grinding and polishing performance. The 9565CV is engineered with Makita's innovative SJS™ mechanical clutch system to protect the gears for longer tool life. The 9565CV is powered by a 13 A motor with soft start for smoother start-ups. The five-stage variable speed dial (2800 to 10,500 rpm) allows the user to match the rpm to the application. The electronic limiter stops the motor and reduces accidental motor overload and burnout and the electronic speed control maintains consistent speed under load. Labyrinth construction protects the motor with a complex set of channels, prohibiting dust and contamination. In addition, the protective zigzag varnish seals the motor and bearings from dust and debris by creating a barrier under rotation. The 9565CV is engineered with SJS™ mechanical clutch system, an innovation from Makita that protects the gears by automatically disengaging the motor should the grinding wheel accidentally catch or bind. The 9565CV is built with comfort and ergonomic features for extended use. The grinder weighs just 5.2 lb with a lock-on switch for easy operation. In addition, the side handle can be easily installed on either side of the tool and the tool-less wheel guard adjustment provides easy clamping. Variable speed for stone work, the 9565CV is a versatile and powerful grinder with variable speed, allowing the user to set the rpm to the material. The variable speed control feature makes the 9565CV ideal for stone work, including polishing and grinding.
