SJS® Super Joint System is a mechanical clutch system that helps prevent motor and gear damage in grinders if the wheel is forced to a stop. 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 allowing the drive shaft to slip. The gear tension is minimized while the armature continues to rotate, which helps prevent motor burn-out. SJS® is a mechanical clutch system, not elecronic, so the grinder does not require a re-start if the wheel binds. [Learn More]
Makita’s 5” SJS™ Angle Grinder combines 13 AMP power with comfort and motor-protection features for longer-lasting industrial performance. The 9565PC is engineered with Makita’s innovative SJS™ mechanical clutch system to protect the gears for longer tool life.
13 AMP Power with SJS™ to Protect Gears
The 9565PC is powered by a 13 AMP motor that delivers 11,500 RPM, with soft start for smooth start-ups. 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 9565PC 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 9565PC weighs just 5.3 lbs. and is built with comfort and ergonomic features for extended use. In addition, the side handle can be easily installed on either side of the tool as well as the top, and the “tool-less” wheel guard adjustment provides easy clamping.
Versatile Design for a Range of Applications
The 9565PC 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.
