Armature MAKITA Grinder (4.5-inch)

A replacement armature for a Makita 4.5-inch angle grinder. The armature is the rotating winding at the heart of the motor, and it is what has usually gone when a grinder loses power, runs hot, sparks heavily at the brushes or stops turning altogether after a hard life on site. Replacing it is routine work for a power-tool repairer and costs a fraction of a new machine, which is why fabricators keep grinders running for years rather than replacing them. Fit new carbon brushes at the same time: worn brushes are often what damaged the old armature, and putting them back will shorten the life of the new one. Whether this part is the manufacturer's own or an aftermarket equivalent is not recorded in our catalogue, and neither is the exact grinder model it is cut for, so confirm the fit with the shop before buying.
