Abstract
1,151,166. Making drills, taps and reamers, cutting tools. KOBE STEEL Ltd. 19 Sept., 1967 [3 Oct., 1966], No. 42695/67. Headings B3A, B3C and B3N. A method of making drills, taps and reamers, having oil passages therein comprises boring at least two holes 2 of larger cross-section than required in the finished drill &c., in a stock material of larger cross-section than the finished drill &c., heating the stock material and elongating it to reduce it to the diameter of the finished drill &c., and thereafter giving the elongated stock material its desired finished form. The holes 2 in the billet 1 may be filled with a heat resisting powder or granular medium 3 such as hard carbon and alumina and then sealed. The heated billet is then either forged by a press, hammer or swager or rolled to reduce it to the drill diameter. The seals are removed or the end of the stock material cut or turned off, to take out the medium 3. The flutes 6 are formed and the material twisted by any known method to provide the final product. In an alternative method, a number of bored lengths of stock material are welded end to end prior to being reduced in diameter, the elongated stock then being cut to the required lengths. In a further method, the terminal ends of the holes are interconnected by a transverse hole (23), copper wires being inserted in all the holes, which are then sealed by plugs (26), (27), Fig. 3 (not shown). The portion of the bar containing the holes is dipped in a salt bath to heat it to about 1000‹ C., whereupon it is extruded in a twist die. It is then hardened at about 1220‹ C., the copper wires melting and flowing out. Finally, it is turned and ground.
