Ordering by number: this is 3310148900, the Atlas Copco piston. The piston is the striking mass of the tool; its condition sets impact energy, so scoring, mushrooming, or lost diameter shows up directly as reduced production.
If you are working from a machine rather than a part number, start at the parts diagram hub, or send us the model and serial and we will match it. Machines themselves are on the Atlas Copco catalog. It ships out of Denver, same day on in-stock orders placed before 4 PM ET.
