Description
Overview:
This Genuine Milwaukee armature is the rotating core of the motor that drives your angle grinder. Built with precision-wound copper coils, a laminated steel core, a machined steel shaft and a copper commutator, it restores smooth, efficient power delivery to the tool. It is designed specifically for Milwaukee HD18AG115-0 and HD18AG125-0 angle grinders and is a direct replacement for OEM No. 4931461676. When an angle grinder shows symptoms such as loss of power, excessive sparking at the brushes or overheating, a worn armature is a common cause. Fitting a quality replacement helps reduce vibration, improves reliability and protects other drive components. Suitable for trade and DIY maintenance of Milwaukee cordless angle grinders that take 115 mm and 125 mm discs, it keeps your tool performing as intended.
