Features of drilling drag bit
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.
Application of drilling drag bit
Used in geological exploration drilling holes, gas drainage hole, grouting hole drilling, suitable for easy paste v
is cosity of soft rock.
