Important Usage Notes

Carbon brushes are among the most commonly replaced power tool components. They gradually wear down through friction and regular use — symptoms of worn brushes include intermittent motor operation, weakened braking, and reduced motor power. If a newly installed brush wears out very rapidly, it may indicate rotor damage; inspect and replace the rotor as needed. Always select the correct brush size and connector type for your specific tool.

Note: Due to varying monitor settings and lighting conditions, the actual item color may differ slightly from product images. Please allow a 1–2 cm tolerance in measurements due to manual measuring.
