The advantage:
Cutting structure
The wear-resistance of teeth is enhanced with premium tungsten carbide hardfacing on the tooth surfaces for steel tooth bit.The durability of premium tungsten carbide inserts is improved with new formulas and new techniques for insert bit.
Gauge structure
Multiple gauge protection with gauge trimmers on the heel and gauge inserts on the gauge surface of the cone ,tungsten carbide inserts and hardfacing on the shirttail increases gauge holding capability and bearing life.
Bearing structure
High precision journal bearing with two thrust faces.Balls lock the cone.The leg bearing can get larger by arranging the rollers in groove of the cone hole,so it can receive mor WOB ,and suitable for high RPM.Thrust faces hardfaced with wear resistant alloy.Abrasion resistance and seizure of the bearing are improved.
Seal and Lubrication
Premium HNBR O-ring,optimal seal compression and curved seal structure can enhance seal performance. The pressure compensator system and advanced grease can greatly increase the lubricating reliability.
Product application
It can receive higher WOB and faster rotary speed than conventional roller bearing bits.It is suitable for high RPM applications.

2, Application for bit
In Petroleum & Gas ,Water well ,Mining and Tectonic Industries ,Oil field, Construction, Geothermal, Directional Boring, and Underground Foundation work.
3,product introduction:
1, Tricone bit
The bit structure
Cone bit is composed by cutting structure, bearing structure, the locking element and oil sealing device, nozzle device, more than 20 kinds of parts .
The leg material is 15CrNiMo,a tricone bit is composed of 3 legs.The cone material is 15CrNi4Mo.The tooth type is include steel tooth and insert tooth.Insert tooth is punch in outside of the cone.The steel tooth is milled from the cone directly.the tooth is engage each other,
Can break comprehensive rock effectively and without repeated and prevent alveolar mudbag .
Bit tooth shape, size, quantity, depending on the drilled strata hardness, formation is soft, then the teeth larger and more pointed, the fewer quantity.
Bit Nozzle type:S-series, P-series,M-series.A bit uaually include 3 or 4 nozzles.Diameter7-14mm. It is fixed in the hydrophthalmia with circlip and sealed with O-ring.
Different tooth corresponding different formation
packaging&Shipping:

How to choose the type:
shallow well, mainly consider the drilling speed and preventing the mud pack.
deep well,mainly consider the bit footage
When out of the well the outer cutter is broken heavily, should be selected with gage bit
In the ease of deviated section should use small and short cutter bit
In the selection of insert button bit, should use the wedge-shaped cutter
Diamond limestone, appropriate uses double bevel gear, projectile shape tooth bit
Shale more or drilling fluid density is larger, should be selected with a larger amount of slip drill
The formation of limestone, sandstone, should choose smaller slip bit
In drilling hard and high abrasive stratum, appropriate uses ball tooth, double cone tooth head.
