I bought a small compressor (6 gallon) and a pneumatic nail gun a while back. work fine and all that. I decided it would be neat to buy some pneumatic tools to use. I was bored at Harbor Freight and bought a right angle drill. hook it up, pulled the trigger.....nothing. It just blasts a bunch of air around the fitting at the drill. I'm stumped. I thought it should be plug and play. Compressor has air and the valve set at 90psi (max psi for the tool). I know HF is just stuff, but it should at least do something...

Am I missing something here?
