Makita Genuine 513791-9 Armature Assembly 110v for HM1810 Hammer Drills

The Makita 513791-9 Armature Assembly is a genuine replacement part designed to restore the motor's core rotating element in compatible 110v Makita demolition hammers and breakers.

Built with precision-wound copper coils on a laminated steel core, this armature delivers efficient power transfer and smooth motor operation. The machined commutator supports stable brush contact, reduces arcing, and helps extend the working life of carbon brushes when the assembly is installed alongside sound bearings.

Designed specifically for 110v site tools, this part is suited to UK construction environments operating on centre-tapped transformer supplies — the standard power arrangement on most managed building sites. It is compatible with the Makita HM1810 and HM0870C, restoring lost impact performance and blow rate in tools that have suffered motor wear or failure.

As a genuine Makita part, the 513791-9 offers an assured fit within its intended models, eliminating the guesswork and fitment risks associated with non-OEM alternatives. The assembly is built to withstand the demanding conditions of demolition work, including exposure to dust, vibration, and continuous heavy-duty use.
