The Makita 516920-3 Armature Assembly is a genuine replacement part for the HM1810 hammer drill, restoring the motor's core rotating element to maintain full impact performance on site. Precision-wound copper coils sit on a laminated steel core, delivering efficient power transfer and smooth running during continuous heavy-duty use. The machined commutator supports stable brush contact, reducing arcing and helping to extend brush life when installed alongside sound bearings and brushes. Rated for 110v operation, this armature is designed for UK construction site power systems using centre-tapped transformers — the standard supply format across most commercial sites and groundworks environments. It is built to withstand the dust, vibration, and sustained shock loads associated with demolition and breaking work. Compatible with the Makita HM1810 and HM0870C, this assembly is suited to straightforward workshop replacement using standard practices. As a genuine Makita part with the correct MPN (516920-3), it provides assured fit and specification accuracy — removing the risk of compatibility issues associated with non-genuine alternatives.
