Makita 644507-2 — Genuine Makita Brush Holder (for DHR263 / DHR264)
Restore reliable electrical contact and quiet running with this original Makita brush holder, part number 644507-2. The molded, heat‑resistant plastic housing with integrated metal contacts secures and guides the carbon brushes so they track correctly against the commutator, reducing arcing and helping the motor run smoothly under load.
Key details
- Part: Brush holder / brush retainer (Makita 644507-2).
- Construction: high‑temperature engineering plastic body with metal contact terminals (designed for vibration and dust from masonry work).
- Quantity: sold as a single brush holder (replace the left or right unit as needed).
Compatibility (example models)
- Fits Makita cordless combination hammers DHR263 and DHR264 (including ZJ variants such as DHR263ZJ / DHR264ZJ).
Notes for repair
- This part is the brush holder body shown in the Makita parts breakdown; the brush holder cap (Makita 643829-7) and carbon brushes (Makita 194928-3 / CB-442) are adjacent items in the assembly and are commonly replaced at the same time if worn.
- Fits directly into the motor housing and installs with the original mounting locations — simple to swap when replacing worn brushes or a cracked holder.
If your DHR263/DHR264 is showing heavy sparking, intermittent power, or the brushes stick in their guides, replacing the 644507-2 brush holder returns proper brush alignment and helps the tool operate as intended.
