Does anyone have pictures, diagrams, drawings or any information on the workings of a pneumatic die grinder?

I tried pulling mine apart this afternoon, but I'd have had to destroy it. I couldn't really get a good look inside.

For those who aren't sure, a die grinder is similar to a dremel, except running from an airline.

hmm i think its like a propeller that spins when air flow through it

I was just looking at some air impact wrenches that claim ~500 lb-ft of torque. Does this rating include the effect of the hammering, or does it mean that if I attached a 1 ft horizontal bar to the end, it would lift 500 lbs?

IIRC, these things use rotary vane motors.

Well if you take off the grinder assembly (only leaving the lever area), and plug some holes, it becomes a blowgun!!! I'm almost done with a coax using a broken one of these as the pilot...

Thanks, this is what I was looking for. I found some pictures on the working of the rotary vane. Looks alright, but could be a PITA to machine.

"Die Grinder" sounds like a vicious German industrial rock band

In fact, it's called a die grinder because it's made for touching up dies..

It is the effect oif the hammering. I highly doubt that it could lift 500lb.

Thought so. So now I need to find a large gasoline engine instead.
