Why You Should Use Carbide Bits and Blades
You may have heard about the benefits of using carbide bits. But what is carbide and why are carbide bits better than other standard industry bits?
What is carbide?
“Carbide” is short for tungsten carbide. Tungsten carbide is typically referred to as simply carbide, despite the inaccuracy of the usage. It is a chemical compound that contains equal parts tungsten and carbon atoms. Carbide comes in a basic gray powder form that can be pressed and formed into unlimited shapes. Since carbide has a higher density than both steel and titanium, it is typically used in industrial machinery, cutting tools, abrasives, armor-piercing rounds, other tools and instruments, and jewelry. It is typically polished and finished with hardened abrasives such as diamonds. The Mohs Scale is used to distinguish the hardness of minerals. Tungsten carbide is a 9 on the Mohs Scale. For comparison, diamond is a 10, steel is a 4-4.5, and gold is 2.5-3.
Carbide is popular in the tool industry because it stays sharper longer than most materials. A good carbide tip can hold an edge 10 to 20 times longer than a steel tip. Using carbide bits and blades guarantees longer, more durable use of the tool. Carbide not only delivers results but is a worthwhile investment, saving the user replacement costs.
