  • 20 carbon brushes supplied across 10 boxes for extended tool maintenance
  • Each brush measures 6.3 x 13.3 x 18.3 mm to match CB153 specifications
  • Spring-loaded design stretches to 37 mm total length for reliable contact
  • Carbon and metal construction suits rotary hammer drills, circular saws and angle grinders
  • Ready-to-install brushes include wire leads and springs for quick replacement

What this pack contains

This pack supplies 20 carbon brushes compatible with Makita CB-153 saws and other power tools. Each brush measures 6.3 x 13.3 x 18.3 mm and includes attached wire leads and springs. Ten boxes of two pieces each are included for workshop or maintenance stock.

Service life under continuous use

Carbon and metal construction resists heat and friction during prolonged cutting or drilling sessions. The spring maintains consistent contact as the brush wears, reducing commutator damage. Total stretched length reaches 37 mm, allowing extended runtime before replacement is required.

Replacing worn motor brushes

These non-OEM brushes replace original CB153 parts when sparking, power loss or intermittent starting appear. The jump is worth it when multiple tools share the same brush size, letting one pack service rotary hammer drills, circular saws, cut-off saws and angle grinders. Builders needing a different form factor should look elsewhere.

Questions about this item

Do the CB153 carbon brushes generate noticeable heat or noise during continuous all-day use in a rotary hammer drill?

Carbon brushes are passive contacts; they produce no audible noise and only minimal heat from normal electrical resistance during extended operation.

What power-tool model must I already own for these 6.3 x 13.3 x 18.3 mm brushes to fit correctly?

They are made for tools that accept Makita CB-153 size brushes, including compatible rotary hammer drills, circular saws, cut-off saws and angle grinders.

Will the 37 mm total spring-stretch length work with the older Makita motor housings I still use?

Yes, the 37 mm stretched length matches the original CB153 specification, so they install directly into the same brush holders on legacy Makita models.
