Makita 643650-4 — Brush Holder Cap (Sold Single) (genuine Makita)

Small but essential: this original Makita brush holder cap threads into the brush holder to secure the carbon brush and keep it aligned for reliable motor contact. It’s specified for carbon brush size 6.5 × 13.5 mm and is listed on Makita parts diagrams as "BRUSH HOLDER CAP 6.5‑13.5."

What you get

- A genuine Makita brush holder cap made to the factory specification so the brush stays seated and contact is stable during operation.

- Matches brush dimensions 6.5 × 13.5 mm (brush cross-section), intended to retain those brushes in the holder.

- Designed to fit the external brush access point used on many Makita corded tools (outer cap diameter noted around 17 mm on parts listings).

Example Makita tools this part is used on (examples only)

- Power planer: 1804N.

- Circular saws: 5402, HS6100, 5007-series.

- Belt sander / sanders and other corded tools such as 9401.

These are representative models that appear on Makita parts diagrams and parts listings showing 643650-4 as the brush holder cap.

Fit/installation note

- The cap screws into the brush holder and is usually replaced in pairs (one per brush) when worn, cracked, or missing—simple to swap during routine brush replacement.

If your tool takes a 6.5 × 13.5 mm carbon brush and has the external brush-access cap, the Makita 643650-4 is the genuine Makita replacement to restore correct brush retention and reliable motor contact.
