5 inch DTH bit high pressure DHD350 130mm to 152mm drill bit for Blast holes
Product Description
In DTH drilling, the rock drilling bit is a continuation of the shank, which the rock drill piston strikes directly. Since the piston is in direct contact with the drill bit, little energy is lost. This gives DTH drilling a nearly constant penetration rate regardless of hole length.
Competitive Advantage
• High grade tungsten carbide inserts
• Bit bodies manufactured from high grade steel and processed using state-of-the-art CNC machinery and heat treatment
Our DTH hammer and bits are compatible with CIR, DHD, QL,SD,Mission, etc. series of Atlas and etc. They are with high efficiency, low failure rate and long service life. They are with high efficiency, low failure rate and long service life, which can realize efficient and economical drilling even for all kinds of high hardness, high abrasive rocks and other harsh conditions.

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.
