From what everyone is saying Ingersoll Rand, Chicago Pneumatic, Bluepoint are the way to go. I have been looking at the 6 different ones on this site someone on here referred me to (bluepoint offer two very similar ones to IR). I don't fully understand all the figures and different specs etc . I am using it for cutting out small areas of rust in places where an angle grinder would be inappropriate and cut surrounding panels etc, just home hobby car restoration. Can people tell me which one they recommend or use and why it is good?
