Why Cobalt Drill Bits Are Best for Metal Work
We often use drills to drill holes in life, for a variety of different materials, we need to choose different drill bits. For metal materials, usually we choose cobalt drill bits, because their performance characteristics make them become the first choice for drilling metal materials:
1.Strong wear resistance
Cobalt drill bits are made of cobalt, cobalt alloy and high-speed steel, which have excellent wear resistance. It can maintain good durability when processing materials with high hardness, and at the same time, it can also make the surface of the drilled hole smooth, which is very reliable in practical application.
2.Good corrosion resistance
Cobalt drill bits not only has wear resistance, but also has good corrosion resistance. Especially when drilling and processing corrosive metal materials, it can effectively resist oxidation and corrosion, and extend the service life of the drill bit.
3.High thermal stability
In the process of high-speed rotation, the drill bit will be subject to greater friction and heat, easy to heat deformation. However, cobalt drill bits have high thermal stability and can maintain stable shape and performance under high temperature to ensure the accuracy and quality of drilling.
4.Wide application
Because of the above excellent characteristics, cobalt drill bits are widely used in the manufacturing industry. It can play excellent performance in drilling and processing common engineering materials, non-ferrous metals, plastics and so on. For example, cobalt drill bits is one of the necessary tools in processing automobile, aircraft, shipbuilding and machinery industries.
5.Reduce production costs
The use of cobalt drill bits can significantly reduce product production costs. Its durability, wear resistance and corrosion resistance can reduce the frequency of drill bit replacement, thus reducing production costs. In addition, due to the high productivity and chemical inertness of cobalt drill bits, it has low processing costs and is able to complete a variety of processing tasks more quickly and efficiently.
In conclusion, cobalt drill bits, as an important tool in the manufacturing industry, have excellent characteristics such as wear resistance, corrosion resistance, thermal stability, etc., and are widely used in various industries. Cobalt drill bits are the best choice for metalworking.
