What is the largest part I can hold in your vise?

The maximum opening on our largest vise is 120 mm (4.72″), but you can hold even larger parts when using the dovetail portion of the vise jaws. We do not provide a maximum part size for a vise. There are many ways to hold a workpiece in our vises. Every application requires a different level of holding force to retain the workpiece firmly. Larger workpieces tend to require higher holding forces to eliminate chatter and vibration and ensure high-quality parts.
