Replacement Carbon Brushes

These carbon brushes measure 14.5mm by 10mm by 6mm and come as a pair. They are designed for generic electric motors found in power tools such as electric hammers, drills and angle grinders. The set suits hobbyists and repairers who need to restore motor function quickly.

Low-friction carbon contact

The carbon and metal construction provides consistent electrical contact with the commutator. Worn brushes often cause intermittent running or loss of electric braking; fitting new ones restores smooth operation. Normal use generates minimal heat and no audible noise.

Direct drop-in fit

Each brush has a total flat length of 40mm (1.6 inches) and weighs 7g for the pair. They install directly into the motor's existing brush holders without modification. The compact size frees up space inside tight tool housings while delivering reliable commutation.

Questions about this item

How do I install the 14.5mm carbon brushes and what is the common mistake?

Slide each brush into the motor's brush holder until the spring seats firmly; the step often missed is aligning the 10mm width and 6mm thickness exactly with the holder slots so the brush face contacts the commutator evenly.

What maintenance or replacement will these carbon brushes need over time?

The carbon material wears down with use; inspect the 40mm total length periodically and replace both brushes once they approach the minimum length stamped on the motor housing to maintain proper spring pressure.

What is the first limit that appears when the motor runs continuously under load?

Heat buildup at the commutator interface causes accelerated carbon wear and reduced spring tension, leading to arcing and intermittent motor performance before the brushes physically wear out.
