DRILL
Document Type and Number:
Japanese Patent JPS5489388
Kind Code:
A
Abstract:
A drilling assembly has a drilling tool which is insertable into a collet chuck of a drilling machine and includes an elongated shaft clamped by the collet chuck, and a longitudinally extending portion on the shaft engageable in a slot between two collets of the collet chuck. The longitudinal portion prevents displacement of the drilling tool relative to the chuck in a circumferential direction. A transversely extending portion is further provided on the shaft so as to abut against an end face of the collet chuck when the drilling tool is clamped therein. These portions may be of one piece with one another and may be manufactured by a stamping process.
