1. Carburizing and surface strengthening process are adopted for the bit body, and the abrasion resistance is increased by more than 5%;
2. Special design of powder discharging trough makes slag discharging smoother and drilling faster;
3. Special tooth layout design and targeted selection of alloy tooth profiles make drilling more efficient;
4. According to different working conditions, different tooth distribution, tooth profile and brand can be selected, especially imported alloy, so that the wear resistance can be improved by more than 10%.
