3M 7010294836 Polisher Armature 120V 28391

Product Description

The 3M 7010294836 is a replacement armature designed for the 3M 28391 Electric Polisher operating at 120 volts. The armature is the rotating core of the motor assembly, responsible for converting electrical energy into the mechanical rotation that drives the polishing head. When an armature fails due to wear, heat damage, or electrical fault, the entire polisher loses function. This part restores the tool to full working condition without requiring full-unit replacement. Installation is performed by qualified repair technicians familiar with electric power tool motor assemblies.

This armature is used as a direct replacement component within the 3M 28391 Electric Polisher, a tool commonly found in automotive finishing, marine detailing, and surface preparation environments. The 28391 is a professional-grade electric polisher, and maintaining it with OEM-specified replacement parts ensures consistent motor performance and balanced rotation. This part is sold individually as a single-unit pack.
