About Model

Makita’s ¼” SJS™ Die Grinder (model GD0800C) combines a powerful 6.6 AMP motor with motor and gear protection features for longer-lasting grinding performance. The GD0800C features a slide switch for increased convenience.

The GD0800C is equipped with SJS™ , an innovative mechanical 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 GD0800C 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 GD0800C 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.


  • Powerful 6.6 AMP motor delivers 7,000-28,000 RPM for faster material removal
  • SJS™ technology is a mechanical clutch system that helps prevent motor and gear damage by allowing the drive shaft to slip if the wheel is forced to stop
  • Variable speed control dial enables user to match the speed to the application
  • Constant speed control automatically applies additional power to the motor to maintain speed under load
  • Soft start suppresses start-up reaction for smooth start-ups and longer gear life
  • Electronic current limiter helps protect the motor from overload
  • Directional air-flow vents channel the tool's air output away from the user's face
  • Labyrinth construction prevents debris from penetrating the motor, bearings and gears for longer tool life
  • Zig-zag varnish protects the armature coil from dust and debris for longer motor life
  • Overall length: 14-5/8"
