DTH Drill Bits Rock Drill Bits For Water Well Drilling
1) Carbide button is made of super-hard tungsten alloy. It has impact resistance, high wear resistance and high thermal stability. The carbide button breaking rate is less than 0.05%.
2) Larger carbide button ,better wear-resistance . 15% increase work life .
3) Drill bit body is made of high-strength high-quality alloy steel. After advanced heat treatment process, the rate of carbide broken is less than 0.05%..
4) Advanced CNC machining and advanced assembly process, carbide button fall down rate is less than 0.05%.

Different face style makes DTH bit is 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.
