- The cutting pick is formed by precise die forging for one time without any machining marks on surface and adopts 42CrMo material.
- Carbide materials adopt low cobalt and ultra-coarse particle tungsten carbide which is wearproof and unbreakable with hardness up to HRA87.7-HRA88.3.
- This cutting pick applies to the coal bed.
- Conform to MT/T246-2006 standards.
