Abstract

1,010,028. Breaking. INGERSOLL-RAND CO. April 30, 1964, No. 18079/64. Heading B3E. [Also in Division B4] A method of making a percussively-operated tool bit (see Division B4), comprises providing an elongated blank 15 of polygonal crosssection, heating an intermediate portion to a predetermined drawing temperature and pulling the blank so as to attenuate the heated portion until it separates. The blank is formed with collars 3 which are mounted in holders 16, 17 adapted to be pulled apart after the intermediate portion of the blank has been heated, e.g. by an electrical induction coil 18. During the pulling operation the intermediate portion necks down until it separates, thereby providing a pair of pointed ends as shown in Fig. 10.
