Review on Enhance Efficiency with Performance Tool M620 4Pc Chisel Set by Patrick Matin

I don't know if this was an isolated problem or not but my used air hammer broke. It won't work, I think there is a leak around the piston. I bought this a few months ago in anticipation of future need so I'm well past the return window. My fault is for not checking it when it first arrived. It feels solid and I think it will probably be ok if you buy a new one. I've had 50-50 on my second hand purchases so far. I think I'll stick to new products from now on.
