I received this vice a few months ago, and have used it a lot on my floor model drill press. Action - after minor adjustment is smooth and precise. I did a lot of checking of other cross-sliding vices and this seemed to be the best for the money. No regrets.
As expected, it is too high for my smaller bench top drill press, and the slots to attach it to the base don't match. To use it on that drill, an adapter plate would be needed, and only a few inches of height would be left for a drill bit. I think 12 in. from base of drill press to end of chuck would be about the minimum to allow effective use of this vice.
Because the crank handle for the bottom cross slide is lower than the base, it has to extend out from the base of the drill press - leaving only a few possible positions for fastening the vice to the drill press - even though there are 3 slots on each side, and one on the end. I found myself wishing for even more flexibility, i.e., more slots, or a sliding method of attachmet. However, if I make an adapter plate to raise the vice about an inch so it can be positioned anywhere on the base using existing slots.
