The Makita GA4553R is a corded 4-1/2 in. paddle switch angle grinder. Its 11 amp motor runs at 11,000 RPM with no load. It suits welders, fabricators, masons and maintenance and repair work.
The guard is non-removable and stays attached to the tool. It rotates quickly without tools. A large paddle switch can be pressed from several grip positions. There is no lock-on switch. A two-stage lock-off switch must be released to start the grinder. Anti-restart protection prevents the motor from starting in the on position after a power disruption. Soft start reduces start-up reaction.
The grinder has a narrow barrel grip and a rubberized side handle. A large spindle lock button makes wheel changes easier with gloves on. An integrated tether loop can be attached to a lanyard when working at heights or on a lift. Spiral bevel gears give smoother rotation and more efficient energy transfer. A labyrinth gear housing cover seals the drive gear and bearings from dust and debris. Zig-zag epoxy on the armature coils protects them from debris while allowing proper heat dissipation.
