YUXIANG bullet teeth is using the best imported high coarse carbide tips to ensure the tops durability in the tough working situation. The high coarse structure’s better heat conduction ability helps to reduce the bullet teeth working temperature.

All the bullet teeth are welded by the automatic welding line for production efficiency. By using heat treatment and welding line integrated method, it only demands one time heating, making the heat disturbing to the carbide tip to the minimum.

You can expect longer working time and less premature wear-out and break failure.

### 💎 Core Materials: Hardcore CP combinations

** Tooth material ** :

42CrMo/30CrMnTi alloy steel 💪

Hardness range: HR48-52 (after quenching) | HRC43-47 (after tempering)

👉 The "skeletal system" equivalent to teeth, impacT-resistant HANDLE!

** Alloy formula ** :

🔹 Tungsten powder (W) → hardness bearing (hardness comparable to diamond!)

🔹 Cobalt (Co) → Toughness King (flexural strength increased by 30%+)

💡 The golden ratio is customizable! Different strata match different formulas:

- Soft rock strata → Cobalt content ↑

- Hard rock strata → Tungsten content ↑
