This is Atlas Copco part number 3315129600 rotation chuck, stocked at Crowder Supply as AC-3315129600. This part keeps the steel captive in the rock drill under repeated impact, so it is inspected at every steel change and replaced on condition rather than on a schedule.
It appears on the DKR 36 36R Rock Drill breakdown. The complete machine is the Atlas Copco DKR36 Pneumatic Rock Drill/Chipping Hammer. Pull up the diagram and confirm the reference number for your serial before ordering.
The rest of the assembly is on the same breakdown, and every diagram we publish is indexed on the full diagram library. Denver stock, with same-day shipment on in-stock orders in by 4 PM ET.
