Abstract
A nose piece for use with an airfeed drill includes a cylindrical portion which has on one end a truncated cone for mounting a drill support bearing and on the other end a flange. Formed within the flange are a plurality of slots. These slots correspond to an array of rotatable fasteners and locking pieces mounted on the front of the housing. Attachment of the nose piece to the housing is accomplished by placing the slots over the fasteners and locking pieces and tightening the fasteners.
