10.5 AMP Motor Delivers 11,000 RPM
The GA5020 is powered by a 10.5 amp motor that delivers 11,000 rpm, with electric brake for maximum productivity. The labyrinth construction seals and protects the motor and bearings from dust and debris for longer tool life. In addition, the armature is sealed by a protective zig-zag varnish which prevents contamination by creating a barrier under rotation.

Super Joint System (SJS) Protects the Gears
The GA5020 is engineered with SJS, an innovation from Makita that protects the gears by automatically disengaging the gears from the motor should the grinding wheel accidentally catch or bind.

Comfort and Ergonomics
The GA5020 weighs just 5.9 pounds and is built with comfort and ergonomic features for extended use. The ergonomic rubberized handle with trigger switch provides easy operation, and the gear housing can be positioned every 90 degrees for operator convenience. In addition, the side handle can be easily installed on either side of the tool.

Versatile Design for a Range of Applications
The GA5020 is a versatile and powerful grinder engineered for demanding applications including cutting, ferrous metal, paint and rust removal, shipyard maintenance, heavy machinery, metal polishing, general steel grinding, auto repair work, cutting brick and masonry, and restoration work. The grinder is built for welders, fabricators, plumbers, masons, electricians, automotive technicians, stone and tile workers, HVAC, and general contractors seeking a best-in-class industrial quality angle grinder. The GA5020 is just another example of Makita's commitment to innovative technology and best-in-class engineering.

Makita SJS LogoAbout 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.
