Carbon carbide tool for the powder metallurgy products, tungsten carbide tool main components of 50% to 90% tungsten, and adding titanium, molybdenum, tantalum and other cobalt powder as a binder, and then heated sintering completed. Carbon tool hardness than any other materials are high, the hardest high-carbon steel three times, for cutting hard metal or stone, because of its material brittle, it can only be made of sheet, and then welded in a more tough Of the knife handle, such as blade passivation or cracking, you can replace the other knife or a new blade, this car is called a turning knife.

    Carbon cutting tool according to the international standard (ISO) its cutting nature of the different, divided into P, M, K three categories, and were blue, yellow, red three colors to identify:

    P01 is suitable for cutting steel, there P01, P10, P20, P30, P40, P50 six categories, P01 for high-speed precision turning knife, the number of small, high wear resistance, P50 for low speed rough knife, , Knife handle blue to identify the.

    K class is suitable for cutting stone, cast iron and other hard and hard materials, K01, K10, K20, K30, K40 five categories, K01 for the high-speed precision turning knife, K40 for the low speed rough knife, such knife handle painted red to identify.

    M class between the P class and M class, suitable for cutting toughness of the larger materials such as not, such as the use of such a handle to yellow to identify it.
