ABSTRACT:
There is disclosed a tool retaining mechanism employing a nose piece including an axially extending, longitudinal bore which accepts the tool bit. The nose piece includes a first opening which is disposed so as to cut through a portion of the bore. Slideably disposed in the opening is a retaining pin which includes a first cutout which cooperates with the profile of the bore and the tool bit, in a first position, to allow insertion or removal of the bit. Means are described for urging the pin axially in its opening to a position where it cooperates with the contour of the bit to retain the latter in the tool once inserted.
