10 Amp 4-1/2 in. Angle Grinder

The 9564P 4-1/2 in. Angle Grinder combines a Makita-built 10 AMP motor with best-in-class durability features to deliver more output power and increased performance. The 9564P is ideal for welders, fabricators, ship yard contractors, masons, electricians, automotive technicians, stone and tile contractors, HVAC, and more.The 9564P is equipped with SJS mechanical clutch syster, a Makita innovation engineered to protect the motor and gears. With SJS, the drive shaft from the armature to the drive gear is spring-loaded during normal grinding load. If binding occurs or the wheel is forced to stop, the spring is compressed, which allows the drive shaft to slip. The result: gear tension is minimized for longer gear life as the armature continues to rotate, which helps prevent motor burn-out.The motor-protection function of SJS is mechanical, not electronic. This is a key point-of-difference, as the mechanical function does not require the contractor to stop and re-start the tool in the event that the wheel is forced to stop. With an electronic clutch, the tool requires a re-start.
