Makita Variable Speed Angle Grinder SJS™II 5" GA5042C

The Makita 5” SJS™II Angle Grinder (GA5042C) combines power, convenience, comfort and motor-protection features for longer-lasting industrial performance. The GA5042C is equipped with SJS™II, a mechanical gear drive system to help prevent motor and gear damage by dampening the force on the gear when the wheel is forced to stop. SJS™II is also features a leaf spring and cam gear drive mechanism that is engineered to reduce vibration for increased operator comfort during extended use. Labyrinth construction protects the motor with a complex set of channels, prohibiting dust and contamination from entering the motor. Additional protection features include a zig-zag epoxy applied to both sides of the armature coil, and a powder-coating to the field. This forms a barrier under rotation and is engineered to protect from dust and debris penetration for longer tool life.
