Advantages of new diamond dive drilling:
The longer life of the drill: the alloy material, with longer using life which better than the similar products
High Drilling Efficiency: the drill buttons is wear-resistant, so that the drill can always keep sharp, thus greatly improving the speed of the drilling
The drilling speed is stable: the bit is scraped and cut to break the rock.
Good Performance: the New Diamond bit has strong wear resistance, good diameter protection and can make
the cutting teeth be used efficiently.
The use of a wide range: the practice proves that the bit is suitable for carbonate rock, limestone, chalk,
clay rock, siltstone, sandstone and other soft and hard (9- grade drillability of rock, hard rock drilling), compared with normal bit, especially drilling in 6-8 grade rock the effect is particularly significant.
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.
