The tip is then inserted, flux is applied to the top, and heating is con- tinued until the coatings melt and run freely. The tip, after coating with flux, is placed in the recess and the shank end is heated. Then a small piece of silver solder, having a melting point of 1325°F (718°C), is placed on top of the tip. When this solder melts, it runs over the nickel-coated surfaces while the tip is held firmly into its seat. The brazed tool should be cooled slowly to avoid cracking due to unequal contraction between the steel and carbide. Carbide Tools.— Cemented or sintered carbides are used in the machine-building and various other industries, chiefly for cutting tools but also for certain other tools or parts subject to considerable abrasion or wear. Carbide cutting tools, when properly selected to obtain the right combination of strength and hardness, are very effective in machining all classes of iron and steel, nonferrous alloys, non-metallic materials, hard rubber, syn- thetic resins, slate, marble, and other materials which would quickly dull steel tools either because of hardness or abrasive action. Carbide cutting tools are not only durable, but capable of exceptionally high cutting speeds. See CEMENTED CARBIDES starting on page 860 for more on these materials. Tungsten carbide is used extensively in cutting cast iron, nonferrous metals that form short chips in cutting, plastics and various other non-metallic materials. A grade having
