This is the Atlas Copco chuck nut part number 3115131300, Crowder SKU AC-3115131300. 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 appears on the BBD 94W 94WS 94WE Rock Drill breakdown. Check it against the reference number on the diagram first; serial breaks change what fits.
Everything else on that machine is one page away on the full diagram library; complete tools are on the Atlas Copco tool range. Ships from our Denver warehouse; in-stock parts ordered by 4 PM ET go out the same day.
