REMOVABLE NOSEPIECES FOR CHUCKS AND SIMILAR TOOL HOLDERS

摘要

A removable nosepiece for a chuck or other similar tool holder has an outer ring of relatively hard and inflexible material such as plastic and/or metal and an inner ring of relatively soft and flexible material such as rubber. The outer ring releasably holds the nosepiece on the distal end of the chuck or other tool holder. A tool is inserted into the chuck or tool holder through a central aperture in the inner ring. The inner ring engages the sides of the tool to help keep dust and debris out of the chuck or tool holder. The nosepiece can be removed and replaced when it becomes worn (e.g., when the inner ring is no longer functional).
