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 the imported JOY coal-winning machine in fully mechanized coal mining and continuous mining for coal bed and half-coal and half-rock coal bed.
  4. Diameter of narrow slot: 30mm; width: 16mm; material of circlip: 65Mn high quality spring steel.
