If you’re rebuilding a drill press or just want a chuck that doesn’t wobble, this is it.

Jacobs is the gold standard for a reason.

Clamps tight, releases easy, and the key is included.

I put one on an old Delta, night and day difference.

Direct replacement for tons of industrial drills.

Grab it before it’s gone.
