  • Countersink bit for glass
    Publication number: 20020004362
    Abstract: A countersink bit for glass has a shaft extending along and rotatable about an axis, a head fixed to the shaft and having a frustoconical surface centered on the axis, a layer of grinding material on the surface, and an axially relatively incompressible plastic body capable of transmitting torque between the surface and the shaft. The plastic body has good damping capabilities so that any tendency of the head to vibrate or chatter is largely eliminated.
