The Makita CB258 Carbon Brush Set (OEM Part No. 191D85-2) is a genuine replacement part designed to restore reliable electrical conduction in Makita GA5050 and GA5050R angle grinders. Carbon brushes are a critical wear component in any angle grinder, transferring electrical current to the rotating armature.
Over time, brushes wear down and must be replaced to maintain consistent motor performance and prevent premature tool failure. As a genuine Makita part, the CB258 is precision-engineered to exact factory tolerances, ensuring a correct fit without modification. This makes installation straightforward and helps get tools back into service quickly — minimising costly downtime on site.
Sourcing genuine OEM parts rather than aftermarket alternatives is particularly important for professional contractors who depend on their tools daily. Genuine components maintain the integrity of the original design and help preserve the longevity of the grinder.
