Products Description
Diamond composite coreless drill bit
PDC coreless drill bits use high-quality diamond composite discs with high-density tooth distribution, which have the
characteristics of requiring grinding and high drilling efficiency. They are suitable for drilling in soft to medium hard
formations (f ≤ 10). Hydraulic design directly washes the cutting tooth front.
It has a high drilling speed and a long service life. Mainly used for drilling gas drainage holes, drainage holes, grouting holes,
geological drilling, hydrological exploration, etc.
1. Used for core drilling in geology, coal fields, metallurgy, building materials, and mines;
2. Used for core engineering exploration and drilling in highways, railways, bridges, housing construction, water and electricity,
etc;
3. Used for grouting reinforcement drilling in weak and dangerous rocks, foundation treatment, and fractured formations;
4. Used for large-diameter engineering drilling, hydrological well drilling, building pile foundation, and inverted hole
construction drilling;
5. Used for monitoring drilling and concrete sampling drilling of tunnel ventilation, exhaust, rock mass buildings.
