The drill bit is a very common and practical tool in our daily life, among which the HSS cobalt drill bit is also a more practical one.

The material of the HSS cobalt drill bit is high-speed steel, a material that combines high hardness, high wear resistance, and high heat resistance. It was created in 1898. After the 1960s, it followed the powder metallurgy high-speed steel technology. The emergence of, the performance has been further improved, the production process of high-speed steel is very complicated, and the production quality is high. Because of their strong hardness and good toughness, the two are suitable and are often used to make metal cutting tools. HSS cobalt drill bit is one of them.

The HSS cobalt drill bit can maintain high hardness even when high heat is generated by high-speed cutting, and the HRC can be above 60. Cemented carbide drill bits have a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance, and corrosion resistance, especially its high hardness and wear resistance, which is not maintained even at a temperature of 500 ℃. Change, still very high hardness at 1000 ℃.

The wood auger drill bit is our most commonly used drill bit.
