Features:
1. 7 blade design, enhancing the density of outer cone teeth and improving the lifespan of the drill bit;
2. Suitable elevation design to balance the impact resistance and attack performance of the drill bit;
3. Double row ruler teeth and appropriate height difference design (depth control) to enhance the impact resistance of the drill bit while reducing the impact on the machine speed;
4. Spacious chip removal groove design improves chip removal capacity, reduces repeated cutting, and increases machine speed;
5. Equipped with imported anti abrasive teeth to improve the lifespan of the drill bit.
Applicable strata:
Strata with high hardness (such as granite and igneous rock), strong abrasiveness, low drilling speed, and low drilling footage per bit.
