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.
Product Advantage
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.
