Carbide Boring Bar

What is carbide boring bar? Carbide boring bar is a type of cutting tool used in metalworking and woodworking. It is made of high-quality tungsten carbide powder and cobalt powder, which makes it highly resistant to wear and corrosion.

Advantages of carbide boring barCarbide boring bar has exceptional hardness, high melting point, and resistance to wear and corrosion. It is ideal for drilling deep holes in the earth's surface and for use in harsh environments.

How is carbide boring bar made?Carbide boring bar is produced using a process called powder metallurgy. Tungsten carbide powder and cobalt powder are mixed together in a ball mill to form a homogeneous mixture. The mixture is then pressed into the desired shape and sintered at high temperatures to form a solid mass.

Applications of carbide boring barCarbide boring bar is used in various applications such as drilling deep holes in the earth's surface, mining, and many more. It is also used in high voltage (HV), radio frequency, and microwave applications.

Maintenance of carbide boring bar To maintain the quality of carbide boring bar, it should be kept clean and dry when not in use. It should also be stored in a cool, dry place to prevent corrosion.
