About
The 5” X-LOCK Angle Grinder (GA5080) offers X-LOCK technology for up to 5-times faster accessory changes than traditional threaded locknut mounting. A click-mount and pull release lever make changing wheels easy. The GA5080 offers a powerful 13.0 AMP motor for more output for demanding applications. The GA5080 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.
It features SJS™ Technology, a mechanical clutch system that helps prevent motor and gear damage by allowing the drive shaft to slip if the wheel is forced to stop. The labyrinth construction seals and protects the motor and bearings from dust and debris for longer tool life. In addition, the armature is sealed by a protective zig-zag varnish which prevents contamination by creating a barrier under rotation. The ball bearing design and metal gear housing provide increased durability.
Other features include constant speed control, soft start, and slide switch with lock-on for continuous use.
Features
TECHNOLOGY

Automatic Speed Change™ is technology that adjusts speed and torque for optimal performance, even in the most demanding applications. During operation, if the tool is put under heavy load, Automatically Speed Change™ detects the added demand and applies more torque and speed to finish the job. Makita cordless tools with Automatic Speed Change™ are engineered to deliver corded performance, without the cord.

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]
