The CB50 / MAK-CB51 12x8x5mm Carbon Brushes are replacement parts designed for the maintenance and repair of brushed electric motors, commonly used in portable power tools.

Carbon brushes are essential components in universal motors, transferring electrical current to the rotor. With use, these parts naturally wear down and may cause power loss, intermittent operation, excessive sparking, difficult start-up or motor stoppage.

Replacing worn brushes can help restore normal tool operation, extend equipment service life and avoid replacing the complete motor or tool.

This pack includes 2 pieces, making it a practical solution for workshops, technical service, preventive maintenance or repair of several compatible tools.
