Enhance Efficiency with Performance Tool M620 4Pc Chisel Set Review

Very strong and great for removing old grout from bricks which other tools cannot. Purchase replacement springs as the spring that holds the chisel in place will break after a few hours of use. Springs are universal and can be found at most air tool retailers. I called Wilmar about the springs and they sent me two sets during the warranty period.

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.

I have not used this spring tool holder. But with my 20-year-old B&D air hammer, the bracket is very tight. So tight that the short end snapped off very easily when I placed 2 Pr Vice Grips on it to expand and "screw" it to the air hammer. So I simply "screwed" the bracket up to the air hammer with a pipe wrench. Because what should have been spring steel broke so easily - I'm concerned about the quality of this retaining spring and whether it will hold and hold tools during a hammer blow…
