Wes, I'm not surprised that the 3/8" drive impact wrench worked to punch
holes in sheet steel boxes, but I didn't have any first hand experience
doing that.

It will still be noisy, but I think it's a better solution than an air
ratchet.

The little 3/8" impact I have is USA Chicago Pneumatic from the 70s, and was
a great tool for auto repair. I have a right-angle head accessory that is
handy for reaching some obstructed fasteners, not quite as compact as an air
ratchet, but really handy at times.

I was thinking that the 1/2" ratchet would have enough torque. The 3/8 impact or 3/8
butterfly impact will work just fine for sure. Small impacts have a purpose also.

I used my brothers 18v drill recently. Two screws later, I was out to my car to get my
much nicer to use and hold 14.4 v drill.

Weight really matters if you have to do repetitive operations.
