Genuine Makita brush holder — part number 643944-7 — a direct-replacement brush holder designed to secure the carbon brush and spring assembly and restore reliable electrical contact to the motor.
This compact component is made with a molded body and metal contact plate so the brush stays seated under spring tension for consistent operation; it’s the small, high‑wear item you swap when brushes don’t make good contact anymore.
Example fitments include Makita 5036D / 5036DWB and 5621RD (fitment can vary by variant and production run, so check your model number before ordering).
Sold singly and ready to install — a simple replacement that gets the motor back to running smoothly. This is a genuine Makita component and a common choice when sourcing quality power tool parts for brush-related repairs.
