This has an Automatic Feed...There is a selector, to where you set how many revs the brace does, before the chain drill will advance...have it set on "1" it can go up to "3"

Chuck has 3 jaws, still had it's springs, too! Mainly for Round shanked twist drill bits,,,up to 1/2" shank.

Might leave this set up as is...and change out to the drill bits as needed..

This works best doing either Posts, or Overhead Beams...

Thanks for looking in..

Thanks for posting this. We need more examples of tools that are available but seldom used.

It has been about 45 years since I last used a chain drill. We used one to drill 3/8" holes in steel pipe. We used a large sweep brace, with one guy running the brace, and one guy VERY slowly advancing the sharp bit. It took a bit of time, but less than you might imagine. At any rate, it was a tool that would do the job that was otherwise almost impossible.
