Bought these for another bank. It's just as good as the old steel version. This 4 inch vise is suitable for use on a DIY workbench. Jaws extend a little more than usual - you can use them on a 5" grip. End of the handle to punch limited and the vise doesn't complain at all. a wedge that can be adjusted to keep the jaws from wobbling, it doesn't have shaft bearings like a milling vise. Couldn't figure it out. Both work great and I like the adjustable outrigger to keep the jaws from swinging.
