Apr 16, 2019· I ended up buying a 10 amp " grinder and some cutoff wheels. I still use the 90 deg air die grinder for small or tight clearance work. I think it's a Campbell/Hausfeld. I work in an industry that uses a lot of pneumatic hand tools. Our brands are , Dessouter Tool, Dotco, Jiffy Tool, Universal...we use IR industrial in our lab.
