Makita’s ¼” SJS™ Paddle Switch Die Grinder (model GD0801C) combines a powerful 6.6 AMP motor with motor and gear protection features for longer-lasting grinding performance. The GD0801C features a large flush-mount paddle switch for increased convenience. The GD0801C is equipped with SJS™ technology, an innovative mechanical clutch system that allows the drive shaft to slip if the wheel suddenly catches or binds. SJS™ is engineered to help protect the gears and motor, and extend grinder life. The GD0801C is powered by a 6.6 AMP motor that delivers 7,000 – 28,000 RPM with soft start for smooth start-ups. The electronic speed control maintains constant speed under load, and a variable speed control dial allows the user to match the speed to the application. Consistent with other models in Makita’s expanding grinder line-up, the GD0801C features labyrinth construction, a series of channels engineered to capture dust and debris and prevent contaminants from penetrating the gear box and front armature bearing for longer tool life. In addition, the protective zig-zag varnish seals the motor and bearings from dust and debris by creating a barrier under rotation.
