    Patent number: 6598884
    Abstract: A collet adaptor and method is provided for adjusting a collet (2) in a machine tool. The collet adaptor has a body or arbor (10) with a cylindrical bore (14) for receiving a cylindrical portion (20) of the collet (2) and a tapered surface (18) at its front end for engagement with a tapered split head (21) portion of the collet (2).
