The Makita GA4530K 4-1/2″ Angle Grinder is a compact, corded grinder designed for metal fabrication, maintenance, and general construction work where control and durability are important. With a 6.0 amp motor delivering up to 11,000 RPM, this 4-1/2″ grinder is suited for grinding, cutting, and sanding applications using standard 4-1/2″ grinding wheels, sanding discs, and wire cup brushes. The slim housing design and ergonomic soft grip help the user maintain control, especially when working in tight spaces or at awkward angles, while the thumb switch with lock-on supports continuous operation.
Built for long service life, the GA4530K uses a labyrinth construction to seal the motor and bearings against dust and debris. Zig-zag varnish on the armature and powder coating on the field add extra protection against abrasion, and machined gears contribute to smooth, consistent power transfer. With only 4.0 lbs of net weight and a side handle for two-handed control, this angle grinder is comfortable to maneuver on site or in the shop. The included plastic carrying case keeps the 4-1/2″ grinder, wheel, and accessories organized for transport and storage between jobs.
