Tungsten carbide cutting tools have gradually replaced high-speed steel tools in turning machining, and so does the tungsten carbide tap. It has been used more and more often in threaded hole machining. Compared with the high-speed steel, the tungsten carbide is of higher hardness and but also higher brittleness, so when using tungsten carbide taps in tapping process, there exits a chip disposal problem. Despite all that, the tungsten carbide tap is still of high efficiency and long service life when used in processing cast iron and aluminium alloy materials. In car industry, the reducing of tap changing times is very competitive and crucial, which can be accomplished by using the tungsten carbide tap due to its long tool life. Using coated tungsten carbide taps with a samll helical angle to perform tapping machining on alumimium workpiece with a silicon content of about 1.5 % can obtain excellent machining effect. What is more, a tap made of submicron-grain tungsten carbide possesses higher toughness while maintains the same hardness, thus can work well in quenched steel, plastics and nickel base alloy cutting.
