Up for sale is a Chicago Pneumatic CP CA048418 set of 2 hammer pins that fits the CP772 / CP772H 3/4” dr. and the industrial models as well. The used parts I have here aren’t questionable or may work as they will work! They are very usable parts and they are priced to make your tool serviceable and or repairable. This came out of a slightly used tool. Like new performance with used pricing. I sell only the tried and true replacement parts that work! Usually ships in 24 hours!
