Makita 638655-7 Spare Part - BRUSH HOLDER UNIT HR2300-2611
Makita 638655-7 — Brush Holder Unit (genuine Makita). Replacement brush-carrier assembly that secures the pair of carbon brushes against the commutator: one-piece molded, heat-resistant polymer housing with metal contact terminals and spring seats to keep brush pressure stable and reduce arcing and overheating during SDS‑Plus hammer drilling.
Fits many Makita SDS‑Plus rotary/combination hammer models including (examples) HR2300, HR2600, HR2601, HR2610, HR2611F / HR2611FT and the HR2630 / HR2631 series — check your model number against this part number 638655‑7 before fitting. This part is listed among Makita parts as the correct brush holder for the models above.
When to use it: replace this holder if the plastic near the motor has melted, become brittle, or if you see excessive sparking, intermittent power or noisy commutator contact. It’s supplied as a single replacement assembly and installs in place of the original holder to restore reliable electrical contact and extend brush and commutator life — a small, common repair that keeps your tool running like new.
Note: part number = 638655-7; intended specifically for the rotary hammer family listed above and categorized among essential parts for power tools.
