Genuine Bosch Collar / claw ring — part no. 1610241001 (1 610 241 001). Precise replacement collar used in the front-end / tool‑holder area of Bosch SDS‑plus rotary hammers. It restores correct seating and alignment of the tool holder assembly so your GBH’s chuck and SDS interface run true under load, reducing play and preventing premature wear of surrounding parts.

Fits key Bosch rotary‑hammer models in the GBH 4‑32 family — most commonly listed for the GBH 4‑32 DFR (Bosch article series 3 611 C32…). Designed to work with the SDS‑plus tool holder / quick‑change front sleeve used on that model. Use the ten‑digit product code on your tool to confirm match.

Construction and use: this small retaining/collar ring is a molded wear‑resistant component (commonly described as a plastic/claw ring) that sits under the front sleeve or locking collar to keep mating components aligned during hammering and rotary action. Supplied as a single, like‑for‑like Bosch part intended for direct replacement—no modification required. Alternate references: 1610241001, 1 610 241 001.

If your GBH 4‑32 DFR shows excessive play at the tool holder, difficulty in seating SDS bits, or uneven wear around the front sleeve, replacing this genuine Bosch collar often restores correct operation and prolongs the life of the tool holder.
