True–Grip Collets

Use your 3-Jawed chucks to hold square stock with no machine change-overs.

V W Broaching Service presents its patented invention, which will precisely center any square stock in a 3-jawed chuck or mating collet without removing or replacing the chuck. The True–Grip chuck adapter is a cylindrical piece of hardened and ground steel. It's slightly slotted and sprung, with undercut corners, so that the square stock can be inserted freely. When the 3-jawed chuck is tightened, the chuck adapter grips the square stock, and exerts equal pressure on all sides, holding it securely in alignment with the center of rotation.

A basic set of adapters includes 1", ¾", ½", and ¼" sizes - packed in its own specially molded case. Custom sizes and shapes are also available.  Contact us for more information.
