This is American Pneumatic Tool part number 1280582260, listed as 01647 before the renumbering steel retainer housing, stocked at Crowder Supply as APT1647. 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 138 Rock Drill and 155 Rock Drill. Worth matching the reference number on the diagram against your own machine before you order the same part number can sit in more than one position.
