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 of 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.Balla lock the cone.Hardfaced head bearing surfaces.Cone bearing inlaid with friction-reducing alloy and then silver-plated.Abrasion resistance and seizure resistance of the bearing are improved.
Seal and Lubrication
Premium HNBR O-ring.optimal seal compression and curved seal structure can enhance the seal performance .The pressure compensator system and advanced grease can greatly increase the lubricating rellability.
Product Application
It can receive high WOB in the conventional drilling.It is suitable for various formations by matching cutting structure with different tooth shape,tooth density ans tooth exposure height.
Recommended Drilling Parameters
| IADC | WOB(WEIGHT BIT DIA) | RPM(R/MIN) | Applicable Formation |
| 437 447 | 0.35-0.9 | 240-70 | Very soft formation with low compressive strength and high drillability.such as clay.mudstone.chalk.gypsum.salt.soft shale.soft limestone.etc. |
| 517 527 | 0.35-1.0 | 220-60 | Soft formation with low compressive strength and high drillability.such as mudstone.gypsum.salt.soft shale.soft limestone.etc. |
| 537 547 | 0.45-1.0 | 220-50 | Soft to medium formations with low compressive strength ,such as medium soft shale.medium soft limestone,medium soft sandstone.medium formation with harder and abrasive interbed,etc. |
| 617 | 0.45-1.1 | 200-50 | Medium hard formations with high compressive strength.such as hard shale.limestone,sandstone.dolomite.etc. |
