Why Replace Your Carbon Brushes?
Carbon brushes transfer electrical current between stationary and rotating parts of an electric motor. Over time, they naturally wear down, causing sparking, reduced power output, or complete motor failure. Regular inspection and timely replacement of motor brushes extends the life of your tools significantly. With 20 brushes in this set, you'll have plenty on hand for multiple tools or future maintenance sessions.
