Why Replace Carbon Brushes Regularly?

Carbon brushes are wear components that transfer electrical current to the motor's rotating armature. Over time, they wear down and can cause reduced performance, sparking, or motor failure. Replacing them promptly keeps your tools running safely and efficiently. For guidance on power tool safety and maintenance, visit the OSHA Power Tools Safety resource.

Note: Monitor and lighting conditions may cause slight color variations between product images and the actual item.
