Abstract
737,246. Percussive drills. SANDVIKENS JERNVERKS AKTIEBOLAG. Nov. 3, 1953 [Nov. 3, 1952], No. 30375/53. Class 124. A rock drill bit has a brazed joint between an insert and a groove in the bit of minimum thickness at the sides intermediate the ends and maximum thickness at the ends. As shown, an insert 11 may have spherically curved sides 12 so that the maximum thickness of the joint 16 is at the outer ends of the insert, the sides of the groove being straight. The sides of the insert may be curved cylindrically, or each side may be formed of straight surfaces meeting at an angle at the centre, or the sides may be stepped, Fig. 8. The sides of the groove may be shaped as above and the sides of the insert straight or the sides of both groove and insert may be shaped. The bottom of the groove and/or the insert may be similarly shaped and used in combination or not with shaped sides of the insert and/or groove.
