Product Description

Tricone Bit, or called Roller Bit, is a most widely used rotary drilling tool for water well drilling and mining, and HDD (horizontal directional drilling) drilling tool. The cutting teeth alternately touch the bottom of the well when the cone bit is working, the rock-breaking torque is small, the contact area between the cutting teeth and the bottom of the well is small, the pressure is higher, and it is easy to enter the stratum.The total length of the working blade is large, thus reducing the wear. It is suitable for varies formations from soft rock to rather hard rock.

(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.

(2) Gauge Structure of this series tricone rock bit :

Multiple gauge protection with gauge trimmers on 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.

(3)Bearing Structure of this series tricone rock bit :

High precision bearing with two thrust faces. Balls lock the cone.Hardface heard 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.

(4)Seal and Lubrication of this series tricone rock bit :

The advanced metal seal package consists of two metal seats and two elastic energizers. Compressed energizers ensure good contact being kept on two sealing surfaces of metal rings by elastic force, and achieve the bearing seal. In the drilling, metal seal 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.
