Abstract

742,281. Making drills. LABBEE, J. A. Sept. 15, 1953, No. 25418/53. Classes 83 (2) and 83 (3). A drill for drilling a screw - receiving countersunk-hole in wood, plastic, brick or metal comprises a piece of flat sheet stock having a tang 19, a countersinking portion 21, 22 and a twisted tapered portion 25. The drill is stamped out of h.s. steel, hardened and then swaged into a head 13. In a modification, a bush 34 is welded, crimped or swaged on the drill to retain a rotatable washer 32. The lower face of the head 13 or the washer 32 acts to limit the depth of hole.
