ABSTRACT:
A sealing collet is provided having a plurality of independent gripping jaws longitudinally disposed about a common centerline axis. The gripping jaws have exposed inner and outer faces. A resilient material is disposed between the gripping jaws and holds the jaws in a predetermined longitudinally and angularly spaced relation about the centerline axis of a collet. A continuous outer diameter seal is disposed circumferentially about the conical outer surface of the collet. The outer diameter seal is formed integral with the resilient material. A continuous inner diameter seal is also provided disposed circumferentially within the inner diameter of the collet and also formed integral with the resilient material. At least one coolant fluid channel may be defined in the resilient material in fluid communication with a coolant port defined through the face of the collet for introducing cooling fluid onto the working surfaces of a tool held by the collet.
