DTH Drill Bits Rock Drill Bits For Water Well Drilling
Main Features
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.
