Genuine 8 Carbon Brush CB 85 HP1631 MT8 Percussion Drill

The Makita CB-85 Carbon Brush (MPN 194973-8) is a genuine Makita spare part designed to restore and maintain reliable motor performance in compatible Makita percussion drills, including the HP1631 and MT8 series. Worn carbon brushes are a common cause of sparking, intermittent running, and loss of power in corded drills. Replacing them with a genuine Makita part ensures correct fitment and restores stable electrical contact between the brush and commutator, supporting smooth startup, consistent speed, and controlled torque under load. Made from high-grade carbon/graphite composition, the CB-85 is engineered for low wear and long service life under typical site and workshop conditions. Correct brush contact also helps protect the commutator from unnecessary wear, contributing to longer overall motor lifespan. This part is suitable for routine maintenance carried out by tradespeople and competent DIY users on Makita corded percussion drills used for drilling and light chiselling tasks. Installation is straightforward with basic tools, making it a practical choice for keeping a drill in reliable working order without the cost of a full motor service.
