DTH Button Bits
DTH drilling is a percussion system driving a piston inside hammer body with up and down motion by compressed air and transmitting an intensive percussion energy to the bit to enable the drilling by crushing the rock. Drilling method by DTH hammer exerts high drilling performance especially for drilling hard rock and contributes for shortening work schedule. Hence, this method is widely utilized for foundation work, landslide prevention work, quarrying services, marine civil work, etc.

Different face style makes DTH bits suitable for various rock conditions.
Flat face: This is an universal design, especially for hard and abrasive rock formation. So typically, flat face with hemi-spherical buttons design is the most popular choice.
Convex face: A classic design for soft to medium hard rock formation which is not so abrasive. This design have very excellent penetration rate but poor in hole deviation if rocks are hard.
Concave face: Medium hard to hard rock formations which is less abrasive and fractured. Especially for deep hole drilling, excellent control over hole deviation.
DGR face: A special design for hard or very hard rock conditions, double gauge row buttons provide very excellent ware-resistance and very longer life time. It is usually used for some bigger diameter DTH bits.
Besides, we are manufacturing the DTH bits with various shanks so they can be compatible with different DTH hammers.
