Our DTH bits are made from high-quality alloy steel and undergo advanced heat treatment, ensuring reliable quality and a long service life. They are available in various face shapes including concave, flat, drop center, and convex.

Features:

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


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. Offers low to medium air pressures and maximum hole deviation control.


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


3. Convex Face: Designed for high penetration rates in soft to medium-hard formations with low to medium air pressures. Offers resistance to steel wash but poor hole deviation control.


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