Tungsten bits, also called tungsten carbide bits, are made of a composite of tungsten and carbide in a cobalt metal matrix. Tungsten bits are among the hardest metals and have a hardness value of around 1600 HV, much higher than that steel. Because tungsten drill bits are so durable and can withstand a high level of wear, they are ideal for drilling almost any type of material, including steel, brick, and abrasive materials.
Tungsten Carbide Cut Edges shave excellent hardness and wear resistance, unlike other bits. These drill bits can bear hammering function and heat resistance. However, they are less durable than steel and cobalt drill bits. For this reason, tungsten carbide bits must be thoroughly cleaned to ensure long-term performance. Tungsten carbide has large particles for larger OD cutters and pads and small particles for smaller tools. The larger particles provide toughness and wear resistance, while the smaller ones fill and surface between the larger ones.
Sustainability
The cutting edges of tungsten drill bits are very durable compared to other metals. However, they must be sharpened to maintain a constant angle while drilling. Tungsten carbide is inserted into the shank to improve edge durability.
Aside Tungsten Powder, Tungsten drill bits are durable and ideal for drilling concrete, bricks, and other hard materials. They can last for many years if properly cared for. They can also be used to drill holes in steel and reinforced concrete. The durability of these bits makes them indispensable in all construction work. Additionally, tungsten drill bits can be used in cement and concrete work.
A tungsten carbide like in Tungco for example cutting edge consists of equal parts of tungsten and carbon. Its hardness makes it more durable than steel and versatile. It can be used in various industries to create multiple cutting edges. Carbide is versatile for cutting edges because it easily cuts many materials. The price of a tungsten carbide cutting edge depends on the type of tungsten carbide it contains, and its quality.
The cost of a tungsten cutting edge during production varies depending on its hardness. High carbon edges are ideal for low-impact, high-abrasion applications but cannot withstand the impact that a through-hardened edge can sustain. On the other hand, a tungsten carbide cutting edge offers 20 times the wear resistance of a standard through-hardened cutting edge. This means fewer edge changes, less downtime, and lower material costs.
