1. Big hole design, chip space is big, high drilling efficiency in soft rock.
2. Cutting free surface, sharp blade, with self-sharpening feature, high drilling efficiency.
3. High resistance to wear.
4. According to stratum characteristics, selecting different drilling and surface structure, bit strong adaptability.
5. High effective utilization rate of drilling time and auxiliary time is short, effectively reduce the labor intensity of workers and good comprehensive benefits.
