Advantages of DTH Drill Bits

1. High Penetration Rates: DTH drill bits are known for their ability to achieve high penetration rates in hard rock formations. The combination of high-quality materials and optimized designs allows for faster and more efficient drilling compared to other methods.

2. Versatility: DTH drill bits are versatile and can be used in a wide range of applications, including mining, construction, geothermal drilling, water well drilling, and exploration drilling. Their ability to handle various rock types makes them suitable for diverse projects.

3. Cost-Effectiveness: Despite their initial higher cost compared to some other drill bits, DTH drill bits offer excellent value over the long term due to their durability and high performance. The increased drilling efficiency results in lower overall drilling costs.

4. Reduced Downtime: The robust construction and high wear resistance of DTH drill bits contribute to reduced downtime for maintenance and replacement, ensuring continuous drilling operations and improved productivity.

5. Improved Hole Quality: DTH drill bits produce clean and straight boreholes with minimal deviation, ensuring accurate drilling results. This is particularly important in applications where precision is paramount, such as in exploration drilling.

How to choose the suitable head face of the DTH drill bit?

1.  Concave:

Suitable for all kinds of formation, especially for deep well drilling, perpendicularity of the hole is wonderful.

1.  Convex: 

Suitable for the formation of moderate hardness stratum, drilling efficiency is good, borehole perpendicularity is moderate.

1.  Flat:        

Suitable for special hard formation stratum, especially for fracture, crack spacing and complex formation drilling effect is very good, has the good perpendicularity of the borehole
 

Product Application

Geothermal well drilling, Water well drilling, Pipe roofing(umbrella arch drilling), Foundation work, Anchoring.
