Every year I get a few calls where a customer needs to grab the ID of a part, but they don’t have a collet chuck or just can’t justify the cost of a complete Expanding Collet Assembly for the one job they’re working on. I usually will suggest that they use a set of Aluminum Full Circle Jaws. Their response to my suggestion is usually one of open mouthed awe, this thought never having occurred to them before.
When using Aluminum Full Circle Jaws for holding the ID of a part, all you have to do is simply turn down the OD (of the jaws) to fit the ID (of the part). Typically, you’d want the ID to be at least 3” or larger. Anything smaller, I’d recommend using a set of standard jaws. Obviously, this will not work for every application, but it is worth a shot when you find yourself in a pinch!
