Nah! Air powered tools ROCK! The shears can cut a 1/4" curlicue-coil of waste out of the centerline between two pieces of 18ga Galvanized and leave close to a sheared edge finish on either side! I've got just about every air tool available that'll run off a 15A job site compressor.

Dremel . . . we don' need no steeeenking Dremel! Not with every kind of die grinder and cutoff wheel available in the toolbox!

The air/hydraulic pop riveter is simply AMAZING! [] ]'>
