Plunger Spring, American Pneumatic Tool part number 1280582923, listed as 17649 before the renumbering, listed at Crowder Supply as APT17649. Springs in a rock drill fatigue with cycle count rather than age, so a control that has gone lazy or fails to return is usually this part rather than the component it drives.
It is called out in the parts diagram for the 109 Mini Rock Drill. The tool itself is the APT 109 Pneumatic Rock Drill.
Work through the rest of the assembly on the same breakdown, or start over from the full diagram library. Denver stock, with same-day shipment on in-stock orders in by 4 PM ET.
