Note: C-657 is my inventory # only. Here is a excellent working used older Snap-On PDR5A 1/2 reversible air drill.
It has a 1/2" Jacobs chuck on it with a capacity of 5/64" thru 1/2. There are no engravings on it. The chuck key handle has a slight bend to it, cosmetic only.
I believe these drills turn at 450 rpm free speed. You may need to change the 1/4 NPT air fitting on the bottom depending on the type of air coupler you have.
