Collet

This is an authentic OEM part that has been sourced directly from Craftsman. The collet is 1/8 of an inch in diameter and is made for multi-tools. A collet is a small piece of aluminum tube that forms a collar around the bits/accessories and holds them onto the tool, they provide the grip required to get the job done. It is important this part is in working order, if it is loose or damaged the bits may not stay in place while you are operating your tool, which is a safety concern. Before starting any repair on your multi-tool make sure it is unplugged.
