Ordering by number: this is 3310103765, which also shows up as 3315129900, the Atlas Copco retainer spring. Retaining the tool steel is its whole job. Worn retention lets the shank hammer against the bore and turns a cheap part into an expensive front head.
It is called out in the parts diagram for the DKR 36 36R Rock Drill. The tool itself is the Atlas Copco DKR36 Pneumatic Rock Drill/Chipping Hammer.
Everything else on that machine is one page away, and the parts diagram hub indexes every breakdown we publish. Ships from our Denver warehouse; in-stock parts ordered by 4 PM ET go out the same day.
