A guy a worked for had an electric impact gun fitted with a nifty drill
chuck: half inch capacity drill chuck and a 1/2" square drive. I'd assemble
trailers with the impact gun, have a suitable drill in the chuck for the
holes that didn't quite line up. Really nice to have the gun switch to
impact mode when it jammed up.

Anyone know where to get such a chuck these days? (Horrible Freight has a
sale on the impact gun)


All mine says on it is "Jacobs No. 64-J9". Pretty sure I've seen them sold
under the Proto and
maybe Snap-On or Mac brands.

1/2" Square drive, 1/8-1/2 capacity, heavy duty keyless chuck. Works great
for drilling
out out of round holes, or lining up holes. A little rough on drill bits.
