  HSS cobalt drill bit is a kind of alloy drill bit. HSS cobalt drill bit is not easy to break and wear resistance, etc. It is very good. Generally speaking, the HSS cobalt drill bit is actually more cost-effective for factories in need. Because the unit price is low and the quality is not bad, generally use the HSS cobalt drill bit. Unless it encounters extremely hard material, the HSS cobalt drill bit will not work, and then choose alloy drill bit.

  General tool steel also belongs to alloy steel, but it is iron-carbon alloy, and high-speed steel is also divided into ordinary high-speed steel and high-quality high-speed steel, so now alloy drills generally refer to carbide drills.

  The material of the HSS cobalt drill bit is a complex alloy steel containing carbide-forming elements such as tungsten, molybdenum, chromium, vanadium, and cobalt. The total amount of alloying elements is about 10-25%. It can maintain high hardness even when high heat is generated by high-speed cutting, and the HRC can be above 60.

  Different drill bits have different performances and different places. Some places need to use the HSS cobalt drill bit, and some need a wood auger drill bit , so which drill bit to use depends on the situation.
