Ordering by number: this is F815426, the Chicago Pneumatic throttle valve bushing. It is part of the operator control on the rock drill. Because it is handled every cycle of every shift, wear here is felt as a vague or sticky trigger long before the machine stops.
It shows up in the parts breakdown for the CP 9RR 9RRS Rock Drill and CP 9BS Rock Drill.
Everything else on that machine is one page away on the full diagram library; complete tools are on the CP tool catalog. It ships out of Denver, same day on in-stock orders placed before 4 PM ET.
