Description
Overview:
The Electric Field (stator/field coil) for Milwaukee HD18PD-32C and HD28PD-32C drills is a genuine Milwaukee replacement designed to restore correct motor performance and torque. Built with insulated copper windings around a laminated steel core, it provides the stationary magnetic field required for brushed DC motors used in many Milwaukee cordless and corded drills. This component helps maintain efficient power delivery, smooth running, and reliable start-up under load. It is suitable for use during routine overhaul or repair when the original field has failed due to wear, heat, or electrical damage. Genuine Milwaukee part, OEM No. 4931440971, for assured fit and performance on the intended tool platforms, helping keep your drill working safely and consistently on site and in the workshop.
