6inch Hard Rock Borehole Drilling DTH Drill Bit with Tungsten Carbide Material
Application
DTH Hammer and bits are used by many drilling professionals related to mining,construction,tunneling,quarrying projects,water well around the globe. JCDRILL company can offer you competitive advantage products, down the hole hammer and bits(dth hammers and dth bits),drill pipes, threaded drilling tools, reverse circulation hammers and bits, shank adapters and coupling sleeves for drilling equipment.
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.
• Underground mining
