The DeWALT NA121629 replacement carbon brush pair is an OEM-quality motor brush set designed for use in compatible DeWALT angle grinders. Carbon brushes are essential wear items in power tools with brushed motors — they provide the electrical contact between the stationary wiring and the motor’s rotating armature. Over time, brushes wear down and can cause reduced motor power, intermittent operation, or motor sparking, so periodic replacement helps restore performance and extend tool life. This brush set is sold as a pair and is suitable for routine service and maintenance on supported DeWALT grinder models.
