CIR90 Low Pressure DTH Button Bits Dia90mm for rock well mine drilling
Product Description
The CIR90 DTH bit is the tool cutting rock. Miroc CIR90 DTH bit for mining is made of superior quality alloy steel .Besides, all our DTH bit is using best quality carbides. In addition art manufacturing technology makes our CIR90 DTH bit for mining is with higher and more reliable quality.
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.
Independently researched and developed alloys with high strength and good abrasion resistance.
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.
