The Makita 7-Inch SJS II™ Angle Grinder (model GA7061) combines power and convenience with comfort and motor-protection features for longer-lasting industrial performance. It is ideal for a range of applications including cutting ferrous metal, paint and rust removal, shipyard maintenance, metal polishing, general steel grinding, auto repair work, cutting brick and masonry, restoration work, and more. It's 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 GA7061 is powered by a 15 AMP motor that delivers 8,500 RPM for the most demanding applications. The redesigned motor is engineered for greater armature stability with larger commutator bars for 3-times longer tool life when compared to the previous model. Additional durability features include labyrinth construction that seals and protects the motor and bearings from dust and debris, and a protective zig-zag varnish on the armature which creates a barrier on rotation to prevent contamination. The rear handle trigger switch has no lock-on and lock-off, so it requires two actions to start the grinder. It includes an AC/DC switch for use with alternative power source.
Excessive vibration in a power tool is wasted motion which may affect a worker’s comfort level and, ultimately, productivity. Makita is bringing unprecedented levels of vibration reduction to the grinder category with the exclusive SJS II™ Technology. SJS™ II is a leaf spring and cam gear drive mechanism that is engineered to reduce vibration for increased operator comfort during extended use. It works by transferring the vibration through the wheel accessory spindle and onto a CAM component. The vibration causes the a cam to press against the leaf spring and absorb vibration for increased operator comfort. [Learn More]
