Cobalt drill bits are also high speed steel drill bits. In fact, the raw material for cobalt drill bit is high speed steel material, but not all high speed steel drill bits can be called cobalt drill bits. There are two types of hss drill bits contain cobalt. M35 and M42, They all have cobalt properties in their materials. M35 has a cobalt content of 5%, and M42 has a cobalt content of 8%. Cobalt is used to produce heat-resistant alloys, hard alloys, and anti-corrosion alloys. An important raw material for magnetic alloys and various cobalt salts.

Cobalt-containing drills are simply the high-speed steel drills containing cobalt. Adding cobalt can improve the high temperature resistance of the drill and make it more wear-resistant.

The hardness of M35 drill bit is usually HRC65-67, and the hardness of M42 drill bit is usually HRC67-70. The price of M35 material is lower than that of M42. These two high-speed steels are more durable than the general-purpose HSS6542 or HSS9341 (hardness 63~66HRC), but the toughness is reduced.

The drill bits made of M35 and M42 materials are called cobalt drill bits. Because of their high hardness, good toughness and reasonable price, they are used as special stainless steel drill bits in the machining industry. Choose a drill bit between the two. When conditions permit, the M42 drill bit is preferred.
