Why Replace Your Carbon Brushes?
Carbon brushes transfer electrical current to the rotating motor armature. Over time they wear down, reducing motor efficiency or causing the tool to stop working entirely. Replacing them promptly with correctly sized brushes keeps your tool performing like new — a simple, cost-effective alternative to full motor replacement.
