Abstract

1470064 Cutting tools; forging FRIED KRUPP GmbH 29 Aug 1974 [30 Aug 1973] 37827/74 Headings B3C and B3H A boring tool comprises a steel body 2 and a screw threaded shank 1 for connecting the tool with a boring shaft, and is characterized by the provision of two opposed flats 7 on the shank so that when the tool is formed in a single forging operation a seam 6 formed thereby lies along a flat and does not protrude to interfere with the screw thread. The tool preferably has soldered-on hard metal cutting plates 3.
