Cemented and Tungsten-Carbide Tools
Samuel L. HoytAbstract
Considerable interest has been shown in the past few years in the new tool materials which have tungsten carbide as a base. The most promising field for the use of these tools is in machining materials which are so abrasive that ordinary tools are speedily worn away or lose their cutting edge, but which do not exert great pressure on the tool. The author points out that the economic value of cemented tungsten carbide is so great in many instances that it at once justifies its use. In some others this will not be so marked and in still other cases its use will be less economical or not at all suitable. Among the latter applications may be mentioned finishing cuts on iron and steel, hogging cuts on steel, or, in general, cuts with heavy feeds and cuts which impose heavy pressures on the tool.
