Bosch 1614336072 — Genuine Bosch brush-holder assembly, designed as a direct replacement for the brush carrier in Bosch GBH 4-32 DFR rotary hammers. This assembly secures the carbon brushes and their spring contacts in the motor housing so brushes maintain consistent pressure on the commutator, helping to stop intermittent power, arcing and uneven brush wear.

Fits example models (illustrative): GBH 4-32 DFR and the associated model 10 digit codes often shown as 3611C32100 / 3611C32101 / 3611C321F0 / 3611C32185 (cross reference with the 10 digit product code from side of the machine to confirm fit). On parts diagrams this item appears as the brush holder block (position 42).

Built to Bosch factory specifications, the part is a compact molded brush carrier with metal terminals and spring anchors for the carbon brushes, made to withstand the vibration and heat inside the hammer drill’s motor. It’s a straightforward swap for worn or cracked holders and is intended to restore reliable motor contact and tool performance.
