OVERVIEW

Restore Precision Performance with the Walter 48H386 Armature

The Walter 48H386 Armature is a critical OEM replacement component designed specifically for the Walter Big 6™ series of angle grinders. As the rotating heart of the electric motor, the armature is responsible for converting electrical energy into mechanical motion. Over time, heavy industrial use can lead to commutator wear, winding fatigue, or insulation breakdown. Replacing a worn armature with this genuine Walter part ensures your tool returns to its factory-specified performance levels.

Engineered with high-grade copper windings and precision-balanced to minimize vibration, this 120V armature protects the longevity of bearings and brushes. It comes complete with the integrated cooling fan and commutator, ready for installation. Using genuine Walter parts is essential for maintaining the safety certifications and operational efficiency of your high-performance grinding tools.
