Note:

  1. The cutting pick is formed by precise die forging for one time without any machining marks on surface and adopts 42CrMo material.
  2. Carbide materials adopt low cobalt and ultra-coarse particle tungsten carbide which is wearproof and unbreakable with hardness up to HRA87.7-HRA88.3.
  3. This cutting pick is mainly used in coal-winning machine for coal cutting in fully mechanized coal mining with high rate of lump coal production.
  4. Conform to MT/T246-2006 standards.
