I'd have to agree with ya 100% Tiny. I've got one and it makes a better HS drill than sander.
I was doing some grinding the other day with a little angle grinder I bought at HF and listening to the 3hp motor hammering away when this thought occurred to me. Wouldn't it be a lot more energy efficient to use one of the 4" electric angle grinders that only draw 5amps on 120v instead of pulling 12amps at 240v to do the same job? The electric grinder is powering a larger disk and like Tiny says, it has more torque.
So what is the advantage of using air over electric in the first place???
