air tools are nice
They run cool, and often have a lot of torque. BUT, they need oil mist in the air to stay working, and that oil often will permeate what you are cutting with it. A definite problem if you want to work on wood. ANd they are even noisier than an electric router, you get noise from the tool and noise from the compressor. If you have larger compressor it may work ok, but a small one will run a lot and start to heat up and build up moisture in the air supply, this then causes more problems and contamination. I use an air die grinder, which is what that tool really is I think, for cutting off pins and grooving threaded pins for glue reliefs, but not precision work. The spindles often have way too much free play for exacting cue work.
