Description
Overview:
This Carbon-Brush Set is a genuine Bosch replacement for the GSB 18V-21 cordless combi drill and compatible GSR 18V-21 drill drivers. The set uses high-grade carbon/graphite blocks with braided copper leads and spring terminations to maintain stable contact with the commutator in a brushed DC motor. Replacing worn brushes restores smooth commutation, helping reduce sparking and heat while keeping torque and speed consistent under load. It is a direct replacement for OEM No. 1607000CZ1 and is designed to fit correctly within the existing brush holders for reliable operation.
