Why Replace Carbon Brushes Regularly?

Carbon brushes are a critical wear component in any electric drill motor. As they wear down, motor efficiency drops and you may notice reduced power, sparking, or intermittent operation. Swapping worn brushes promptly keeps your drill operating safely and extends the overall service life of the motor.
