Why is tungsten carbide used for cutting tools?


Tungsten carbide, also known as “carbide,” is a compound of tungsten and carbon. Its use in cutting metals has revolutionized the metalworking industry, enabling higher cutting speeds and feeds while extending tool life. Tungsten carbide was first investigated as a cutting tool material in 1925, when General Electric’s Carboloy division began to produce cutting tools. However, in the late 1930s, Philip McKenna discovered that a new compound of tin and titanium had been made by the company Kennametal. In the late 1930s, the tools improved even further.

Tungsten carbide tools are produced with sintered blanks, which require minimal treatment. After sintering, many cutting tools require peripheral grinding to sharpen their cutting edges. These grinding processes can also recycle the wear debris left by the grinding process. During this process, the entire cutting tool is polished and honed. Tungsten carbide cutting tools are used in a variety of industries. These cutting tools are extremely durable and can handle a wide range of applications.

The process of creating tungsten carbide includes two steps. The first is milling the ore into powder. This process produces a free-flowing mass. The next step is adding an organic binder to agglomerate the tin. The organic binder is used to tailor the fluidity and charge density of the material. Afterward, the milled powder is spray dried. The coating has a hard, oxidized coating and a smooth surface.

The second stage involves mixing the powder with a metal bond. WC-Co tungsten carbide is a cemented tungsten carbide tool that contains 86.5% carbide and 10% cobalt and 3.5% chromium. This powder is applied by physical or chemical vapour deposition techniques, and the resulting tool has a significantly higher toughness than uncoated ones. There are several other benefits to tungsten carbide, however.

Tungsten carbide tools are very rigid. Compared to steel and cast iron, tungsten carbide is twice as stiff and durable. Tungsten carbide tools are more durable than any other material. For instance, a Tungsten carbide drill bit may last longer than a steel drill bit, but a tipped tool will still cut a lot of materials. This means that you can reuse a tungsten carbide blade and earn money from it.

Tungsten carbide is also extremely durable. When properly used, tungsten carbide tools will last a long time and are less likely to wear out. They can be repaired or replaced quickly and easily, and a good tungsten carbide drill will reduce the need for frequent replacement. You will also be able to cut through any kind of ferrous material with a Tungsten carbide tool. There is no better investment than a Tungsten carbide saw!

Final Touch

Tungsten carbide is also a valuable metal. It is gray and can be purchased in powder form. Its strength makes it a good choice for woodworking. Despite the high cost of tungsten carbide, it is worth the extra cost. And while the price tag is more expensive than steel, the benefits of Tungsten carbide tools are significant. The material can withstand higher temperatures, and it is resistant to wear.
