They do have pneumatic versions, should you have shop air. These tend
to be smaller and lighter for the same work capacity and readily
throttled. They had air routers at the motor home plant for doing
cutouts that had throttles on them, seemed to have plenty of power.
Pneumatics don't have the heat buildup problems that electric motors
do, just need good lubrication.
