Our DTH bits are made from high-quality alloy steel and undergo advanced heat treatment, ensuring reliable quality and a long service life. We offer various bit face shapes including concave, flat, drop center, and convex to cater to different drilling needs.


Features:



  1. Reliable quality and long service life, with rare abnormal breakage during operation.

  2. Good flushing effect for high drilling rates.

  3. Strict quality warranty and compensation rules.


Bit Face Shape Selection:



  1. Drop Center Bit: Ideal for high penetration rates in soft to medium hard and fissured rock formations. Provides maximum hole deviation control at low to medium air pressures.

  2. Concave Face: Suitable for medium hard and homogeneous rock formations. Offers good hole deviation control and flushing capacity.

  3. Convex Face: Provides high penetration rates in soft to medium-hard formations with low to medium air pressures. Resistant to steel wash but may have poor hole deviation control.

  4. Flat Face: Designed for hard to very hard and abrasive rock formations with high air pressures. Offers good penetration rates and resistance to steel wash.
