PLASTIC GRIP BOOTS FOR CHUCKS

摘要

A plastic grip boot for a metal part of a chuck, typically a keyless chuck, is disclosed. The grip boot is insert molded to a rotatable metal part of a chuck, the metal part extending under the grip boot for the axial length of the grip boot which is normally gripped by the user in order to provide support to the grip boot. During molding, the plastic preferably flows into surface features of the metal part to help secure the grip boot to the metal part. The grip boot improves user grip of the metal part during operation of the chuck to adjust the spacing of the chuck jaws.
