Each brush (CB-318) measures approximately 5 × 11 × 16 mm (thickness × width × length), made of graphite carbon formulated for reliable contact and long brush life in high-speed motors. Fits the factory brush holder arrangement used on many Makita grinders and handheld motor tools.

Use these model examples to confirm fit for your tool.
Why buy this part: simple direct replacement of worn brushes restores brush-to-commutator contact, reduces arcing and motor noise, and helps the tool regain full power and smooth operation. Supplied as the original Makita brush set, ready to install — ideal when you need the correct brush size and fit without modification.
