6.6 AMP Power with SJS to Protect Gears
The GD0800C is powered by a 6.6 AMP motor that delivers 7,000 to 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 RPM to the application. Labyrinth construction protects the motor with a complex set of channels, prohibiting dust and contamination. In addition, the protective zig-zag varnish seals the motor and bearings from dust and debris by creating a barrier under rotation. The GD0800C 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.

Comfort and Ergonomics
The GD0800C weighs just 3.5 pounds and is built with comfort and ergonomic features for extended use. The slender double-neck aluminum gear housing is designed for easy handling, and the slide switch is positioned on the small circumference barrel grip for easy operation. A side handle can be easily installed on the side of the tool.

Versatile Design for a Range of Applications
The GD0800C is a versatile and powerful die grinder engineered for a range of applications including pipe fittings and small scale grinding. The GD0800C is built for welders, plumbers, ship builders, automotive technicians, HVAC, and general contractors seeking a best-in-class industrial quality die grinder. The GD0800C is just another example of Makita's commitment to innovative technology and best-in-class engineering.

About Makita's Super Joint System (SJS)
Super Joint System (SJS) is an innovation from Makita engineering where the motor armature and spiral bevel gear are linked by a coil spring. If the grinding wheel catches or binds, the coil spring relaxes and disengages the gears from the motor. As the grinding wheel stops, the gears and motor are protected. Makita's growing line of SJS-equipped grinders includes models ranging from a 1/4-inch die grinder to a 7-inch angle grinder.
