Details:

Makita’s 1/4 in. 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 – 29,000 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.
