Abstract
616,116. Making cutting tools. BOLD, H. Aug. 28, 1946, No. 25752. [Classes 83 (ii), 83 (iii) and 83 (iv)] Drills and cutters; powder metallurgy.- Cutting-tools are produced by mounting a carbide blank in the chalk stage on a mandrel by means of a spigot-and-socket connection, machining the blank whilst on the mandrel, removing the blank from the mandrel, sintering the machined blank to convert it to a cutting head and then mounting the head on a suitable shank by aid of part of the spigot-and-socket connection. A rotary cutting-tool is produced by moulding and preliminary sintering at low temperature a block of tungsten &c. carbide, then drilling and tapping a countersunk hole 2 and mounting the block on a spigot 5 on a mandrel 4. The block 2 is then machined and removed from the mandrel and sintered at a high temperature to form the cutting head. The head is then mounted on another mandrel of smaller diameter and secured by brazing. The spigot may be formed on the cutting-head. The spigot or socket on the blank may be formed as a tap or die for screw-cutting the mandrel and the socket connection may be formed of tapered or angular cross-section.
