I am looking for feedback both positive and negative on the use of these clamps. They are great on the drill presses and my homemade clamp table for holding everything from boards to metal parts. I adapted them to my mill tables by using 12mm Tee Nuts. They are great so far for quick and light milling. As you can see they will work up to 4" . Could be taller if some adapters were made. Any ideas of improved uses are welcomed. I have not found it necessary to use a vice on a drill press since I bought my first set. I now have 4 of them. And bought my son 2 of them for the drill press I gave him.
