12 Amp 4-1/2 in. SJS II High-Power Angle Grinder

The Makita 5 in. SJS II High Power Angle Grinder (GA5042C) combines power, convenience, comfort and motor-protection features for longer-lasting industrial performance. It is ideal for cutting, grinding ferrous metal, paint and rust removal, shipyard maintenance, metal polishing, general steel grinding, auto repair work, cutting brick and masonry, restoration work and more. 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. The 12 Amp motor delivers 2,800-11,000 RPM for versatility and maximum productivity. 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.

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.

Makita 5 in. SJS Angle Grinder combines 13 Amp power and variable speed with comfort and motor-protection features for longer-lasting industrial performance. The 9565PCV is engineered with Makita's innovative SJS mechanical clutch system to protect the gears for longer tool life. The 9565PCV is powered by a 13 Amp motor that delivers 2,800 - 10,500 RPM, with soft start for smooth start-ups. Labyrinth construction seals and protects the motor and bearings from dust and debris for longer tool life. In addition, the protective zigzag varnish seals the motor and bearings from dust and debris by creating a barrier under rotation. The 9565PCV 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. The 9565PCV weighs only 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. The large paddle switch with lock-off is designed for more comfortable operation. The 9565PCV 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 Makita 5 in. High power Angle Grinder with Brake (GA5091) features a powerful 15 AMP motor that delivers more output and features a variable speed control dial that allows the user to adjust RPM from 2,800 - 11,500 to match the speed to the application. The High-Power Angle Grinder features SJSII, which uses a leaf spring and cam gear drive mechanism that is engineered to reduce vibration for increased operator comfort during extended use. Vibration is further reduced by the vibration-absorbing side handle which provides increased comfort on the job. The GA5091 features an Electronic Controller that provides soft start, which is designed to suppress start-up reaction for smooth start-ups and longer gear life. The High-Power grinder features labyrinth construction seals and protects the motor and bearings from dust and debris for longer tool life. The motor fan is designed with enlarged fins for increased air flow and a cooler running motor. The GA5091 features spiral bevel gears for smoother rotations and a more efficient transfer of energy. It features a fully aluminum constructed gear housing which provides superior gear alignment and smooth transmission for increased durability and comfort. An Electronic Controller provides an electronic current limiter which helps protect the motor from overload in high-torque applications. Convenience features include a in. tool-less in. wheel guard for easy adjustment and a slide switch with lock-on for continuous use.
