This is the Atlas Copco rotation chuck bushing part number 3115174800, Crowder SKU AC-3115174800. 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.
You will find it on the diagram for the RH 658L/LS/LS-01 Rock Drill and RH 656W Rock Drill. That machine is the RH 658 L Surface Rock Drill if you are pricing a replacement rather than a repair. Check it against the reference number on the diagram first; serial breaks change what fits.
The rest of the assembly is on the same breakdown, and every diagram we publish is indexed on the parts breakdown index. Ships from our Denver warehouse; in-stock parts ordered by 4 PM ET go out the same day.
