I remember when I was a kid drilling 4 ½” exhaust holes through the 2” transom of a boat with a hole saw and a huge electric drill motor. I remember the hole saw locking up and me being spun upside down and dropped on my head, (explains a lot I guess). Since then I have always stayed away from electric power tools. But, I know some women that swear by electric power tools……………………….

Thanks for the advice rebocardo (you too Eric!),
I had made a decision yesterday on a unit which incorporated all of the advice from rebocardo (and others) and went to make the purchase. There was a sale on and, sure enough, they were sold out. I got a rain check so I'll get her eventually. What a let down. I was looking forward to boring some holes last night but all I ended up boring was my family.
I found a 1/2" heavy duty reversible drill (500 rpm) with reverse gear and adjustable side handle. I think I'll pick up a 3/8" right angle drill too (1800rpm). These should do the trick. There is also battery and corded in the shop too so I should have making holes covered.
Thanks again,
Gil

If you don't get a variable speed air drill you purchase small valve to cut back the air volume to reduce rpms. This will save you a fortune in drill bits. Turning a bit faster than 500 rpms even in mild steel will smoke the bit PDQ. High speed is ok in soft matierials like aluminum and sheet metal, but in the hard stuff I like 150- 200 rpms.

I like the slower RPM of an air drill like the 1/2" 500RPM, for metal work anyways. You get a better cut and longer bit life, which is a plus because good drill bits can really be expensive.
