The tricone bit is the most versatile drill bit on the market. It is the go-to drill bit in most styles of drilling. Whether you are drilling a water well or an oil well, the long established 30-year-old manufacturer Beijing Superior Drilling Equipment has the Tri Cone Drill Bit for you.Our product line also includes tungsten carbide insert (TCI) bits and steel tooth bits for the toughest drilling applications.
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 (in the outer row)and gauge inserts on the gauge surface of the cone, tungsten carbide and hardfacing on the shirttail increases gauge holding capacity and bearing life.
Bearing Structure:
High precision journal bearing with two thrust faces. Balls lock the cone.Hardfaced 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:
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 reliability.
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 and tooth exposure height.
