Makita Genuine 638655-7 Brush Holder Unit for Makita HR2600, HR2601 Hammer Drills

The Makita Genuine Brush Holder Unit (MPN 638655-7) is a replacement assembly designed to secure the carbon brush pair around the commutator in Makita HR2600 and HR2601 rotary hammer drills.

Constructed with a durable, heat-resistant polymer housing and metal terminals, this one-piece unit maintains consistent brush pressure through stable spring seating. This helps reduce arcing, heat build-up, and intermittent power issues that are common signs of worn or misaligned brush assemblies in heavily used SDS-Plus hammer drills.

As a genuine Makita spare part, it is engineered to the correct specification for the listed models, ensuring a reliable fit without the guesswork associated with non-OEM alternatives. It is equally suited to routine preventative maintenance and reactive repair work where electrical contact has become unreliable.

Whether you are a contractor keeping tools operational on site or a workshop technician carrying out scheduled servicing, this brush holder unit supports smooth, consistent motor performance and helps extend the working life of both the brushes and commutator.
