HIKOKI Armature

HIKOKI Armature Overview

This genuine Armature 230-240 Volt is a direct replacement for Hikoki and Hitachi disc grinders, engineered to restore smooth, reliable motor performance in models such as G13SB3 and CM5SB. The assembly features copper windings on a laminated steel core with a precision-machined commutator, providing efficient energy transfer and stable speed under load. Built for UK mains voltage, it converts electrical power into rotational drive, forming the heart of the grinder’s motor. The robust steel shaft and balanced rotor help minimise vibration and wear, supporting accurate grinding and cutting. It is suitable for routine maintenance or repair where the original armature shows signs of overheating, commutator damage, or winding failure. Genuine Part for assured fit and compatibility.
