Rotary Button Bit IADC537 3 7/8″ (98mm)
Product Description
TCI Teeth Elastomer sealed bearing tricone rock bit in the stock.
Cutting Structure
The durability of premium tungsten carbide insert is improved with new formulas and new techniques for insert bit.
Gauge Structure
Multiple gauge proteciton with gauge trimmers on the heel of cone,tungsten carbide inserts and hardfacing on shirttail increases gauge holding capability and bearing life.
Bearing Structure
High precision bearing with two thrust faces.Ball lock the cone.Hardfaced head bearing surface.Cone bearing inlaid with friction-reducing alloy and then silvery-plated.Abrasion resistance and seizure resistance of the bearing are improved.
Sealed and Lubrication
Premium 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 reliability.
3 7/8 inches (98mm) API TCI Tricone Bits for Hard Rock Drilling
98mm tricone bit is small size.The connection thread is 2 3/8 reg pin.
According to cutting material,tirocne bit can be divided into TCI bit and Steel Tooth Bit .TCI button drill bit IADC537 3 7/8 inches 3 cone bits are always used in shallow water well drilling , geothermal well drilling and grouting hole drilling, sealed / closed bearing extends the working life, tungsten carbide inserts gauge protection on heel of cones protects cone body from being wore.
We always care the following details: Rock bit's working life ,Penetration rate of rock bits,Cost of drilling per meter/feet.
