Model NO.: IADC115 16inch 406.4mm
Package: Wooden Case
Trademark: ouyate
Specification: ISO9001
Origin: Hebei Hejian
HS Code: 82071990
Model NO.: IADC115 16inch 406.4mm
Package: Wooden Case
Trademark: ouyate
Specification: ISO9001
Origin: Hebei Hejian
HS Code: 82071990
Applicable Formations
Medium to hard hardness formations with low compressive strength, such as medium, soft shale, medium soft limestone, medium soft sandstone, medium formation with harder and abrasive interbeds, etc

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. Hardraced head bearing surface. Cone bearing inlaid with friction-reducing alloy and then silver-plated. Abrasion resistance and seizure resistance of the bearing are improved, and suitable for high rotary speed.
Seal and lubrication
The advanced metal seal package consists of two metal seals and two elastic energizers. Compressed energizers ensure good contact being kept on two sealing surfaces of metal rings by elastic force, and achieves the bearing seal. In the drilling, metal seals are relatively dynamic, and the energizers are static. This will improve the reliability and durability of bearing seal. 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.
