Rotation Chuck Nut, Chicago Pneumatic part number R086733 (also carried as 3310103643), listed at Crowder Supply as CP-R086733. 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 shows up in the parts breakdown for the CP 0032 Rock Drill and CP 0069 Rock Drill, and on 2 other machines. Check it against the reference number on the diagram first; serial breaks change what fits.
If you need the parts around it, the parts diagram hub has the full breakdown library, and the CP tool catalog covers the machines themselves. Ships from our Denver warehouse; in-stock parts ordered by 4 PM ET go out the same day.
