Abstract
760,353. Drills. ASPLUND, A. J. A., [trading as MASKINFIRMA R. L. CARLSTEDT]. Feb. 12, 1954 [Feb. 14, 1953], No. 4169/54. Class 83 (3). A drill comprises a hollow carrier 10 secured to a shank 16, and a cutter 18 secured to the end of the carrier, the cutter being made of a harder metal than the carrier and extending across the carrier to provide at least one cuting-edge 26 projecting outwardly of one side of the carrier, and a guiding-shoulder 30 at the opposite side. A separate guide 32, Fig. 2, is provided in advance of the cutting-edges 26, 28, and a throat 34 for the passage of chips and coolant. In a modification, the carrier-wall adjacent the cutting-edge 28 may be constituted by, or covered with, material of the same, or approximately the same, hardness as that of the cutter.
