This Makita 5 in. SJS Angle Grinder combines 12 Amp variable speed power in a lightweight design with motor-protection features for longer-lasting stone grinding and polishing performance. It’s engineered with Makita’s innovative Super Joint System (SJS) technology to protect the motor from gear damage by allowing the drive shaft to slip if the wheel is forced to stop. A 5-stage， variable speed dial lets you match RPMs to the application. Smart， labyrinth-style construction seals and protects the motor and bearings from dust and debris for a longer tool life. The grinder weighs just 4 lbs. and features a versatile side handle that can be installed on either side of the tool.
