Over the years I have injured myself several times from not properly fixing something I was drilling to the table. Ruined a few bits too. We have all done it one time or another. The standard drill press vice is a PIA to use. I even let a vise get away from me because I didn't fix it to the table. Most of the time the damage isn't serious, but it can be. I have tried dozens of vises, but none have really been satisfactory.
A couple of months ago I scored a 4 "Heinrich TS vise thrown in with the purchase of a drill press. This thing is great. It's easy to use. It is easily posititionable over the table and is very secure. Note the square bar set up. That is the secret. The fact that there is no clamping screw makes it easy. Just push the jaw into position and push down the lock. The jaws have a built in step which eliminates the worry of drilling into the vise or table. The whole assembly can be quickly slid off the table in case you need to use something else.
Yeah, they are a little pricey, but my last injury cost me a lot more. Well worth considering. I also noticed that Northern Tool has a Wilton knock off. I would imagine that there are others.
Check them out.
