This Carbon-Brush Set is a Genuine Bosch replacement for selected corded power tools, including the CSB 700-2 RLT and CSB 650-2 RET. Supplied under Bosch MPN 2604321905, the set uses high‐quality carbon to provide consistent electrical contact with the motor commutator, helping to restore torque, reduce sparking, and keep the tool running efficiently.
