ABSTRACT:
The chuck assembly and the collet for retaining an end mill tool against axial pullout. The collet includes a radially compressible body having a tapered outer surface, a central bore and a radial aperture extending from the outer surface into the central bore. The radial aperture has an undercut or larger diameter medial portion with a movable pin mounted therein, said pin being movably mounted and, adapted to extend into the bore to retain the tool. The pin has a hole drilled through with a spring bar mounted therein. The ends of the spring bar are compressed to a length smaller than the diameter of the radial aperture and inserted into the larger undercut portions where the expansion of the spring bar retains the pin. The hole in the pin is larger than the diameter of the spring bar to allow the pin to move along its axis (radially into the collet bar). The pin has a lower chamfered end which is urged inwardly into the bore as the collet is tightened in the chuck assembly with the chamfered end engaging a rear bevel end on a flat surface on the tool to secure the tool within the collet, and whereby the pin can move outwardly to release the tool when the collet is removed from the chuck assembly.
