What about an industrial electric die (straight) grinder ? They are 
somewhat larger than Dremel but this ain't a problem if mounted in a 
good press. At least you don't need a whopping big compressor thumping 
in the background to drive it. The Dremel I once had was so out of round 
you could see the drill tip blur when it was running. Everything is made 
to a price.
