This is American Pneumatic Tool part number 1280583028, listed as 18706 before the renumbering lock ring, stocked at Crowder Supply as APT18706. It locates or retains an assembly inside the scaler. Small as it is, a sheared or walked-out pin lets a whole subassembly shift.
It is called out in the parts diagram for the 307 & 317 Needle Scaler. That machine is the APT 307 Pneumatic Needle Scaler if you are pricing a replacement rather than a repair. Pull up the diagram and confirm the reference number for your serial before ordering.
Work through the rest of the assembly on the same breakdown, or start over from the parts diagram library. Denver stock, with same-day shipment on in-stock orders in by 4 PM ET.
