Industrial and Scientific Workholding is tough to find, and it's even harder to come across a good one. Through trial and error, I found that these Workholding tools are impressive. They work exceptionally well- the clamp is sturdy, and the jaws have a great grip to hold the workpiece in place. Additionally, it's easy to adjust and to switch out parts. However, they are bulky and can take up a lot of space in a toolbox.
