Use our new Crank Handle (does not include Holster) with existing machine vises to increase speed and ease of operation. This is a premium vise handle made in the USA from steel with black oxide finish. This handle is built to last and makes life easier for Machinists & Operators. This handle works with most standard vises that have a ¾” hex drive. The Crank Handle works best when your vise is hanging off the table providing proper clearance. You can also purchase extensions in 2 ½” or 3 ½” lengths. This model is a good option when machine vise screws are not operating smoothly, and additional leverage is necessary.
