Abstract
A collet chuck for use in boring through a workpiece that provides a cooling and cleaning fluid to the element that is machining the workpiece. One end of the collet chuck is coupled to the drive end of a motor and its other end retains the machining element. The motor provides a rotational force to the collet chuck and machining element used in machining the workpiece. The machining element, which can be a drill bit or reamer, includes an axial passage that communicates with an annulus in the chuck. The cooling/cleaning fluid flows into the annulus through a rotary seal that circumscribes the collet chuck.
