Foredom Mandrel Screw for Cone Sanders 1/8" Shank.  Tapered or spiral mandrels allow you to screw the accessory down onto the threads of the mandrel and, once rotation begins, it will automatically tighten onto the widening taper. This open thread design provides good stability throughout the length of the accessory.
