16'' Three Cone Button Tricone Drill Bit For Borehole Water Well Drilling
(1) Cutting Structure of this series tricone rock bit :
The durability of premium tungsten carbide inserts is improved with new formulas and new techniques for insert bit.The wear-resistance of teeth is enhanced with premium tungsten carbide hardfacing on the tooth surfaces for steel tooth bit.
16" IADC637 TCI Tricone Bit, which some may also call roller cone bits or tri-cone bits, have three cones. Each cone can be rotated individually when the drill string rotates the body of the bit. The cones have roller bearings fitted at the time of assembly. The rolling cutting bits can be used to drill any formations if the proper cutter, bearing, and nozzle are selected.
We are a professional company in supplying tricone bits,steel teeth bits,single cone bits,and PDC bits.
Bits sizes range from 3 7/8” to 26”.and cover almost all IADC codes.It can be used in various of different fields,mining,hydrology,subterranean heatpilling,water well drilling and oil well drilling.This type of bits have optimal bearing design, it can be working stably in high WOB,and the qualtiy tungsten carbide inserts on cone and the gauge make a good wear resistance largely extend the working life of bits.It is suitable for medium to hard formation.
