Description
Overview:
This 240 V armature is a genuine Makita replacement for the HR2460 and HR2470 rotary hammer drills. It is the rotating core of the motor, built with copper windings, stacked steel laminations, a precision-machined commutator, and a robust steel shaft. Replacing a worn or burnt armature restores smooth motor operation, consistent speed, and proper torque under load. Designed for UK mains-powered rotary hammers, it helps the tool run efficiently and reliably during drilling and chiselling tasks. As an OEM part (No. 517984-0), it is made to the original specification for accurate fit and performance, helping reduce downtime and extend the service life of your Makita hammer drill.
