Chinese manufacturers provide  durable   milled tooth tricone rock bit

Product Description


Drilling Tools can hard face the milled teeth so that they sharpen themselves while drilling. 

Milled tooth tricone bits are designed for very soft to medium hardness formations.

Open Bearing mill tooth Tri-Cone roller cone bit can come with or without gauge protection.

These are less expensive than sealed bearing but they typically do not last as long.

 Guage protection increases the life of the drill bit.

Cutting Structure
The wear-resistance of the teeth is enhanced with premium tungsten carbide hardfacing on the tooth surfaces for the steel tooth bit.The durability of premium tungsten carbide inserts is improved with new formulas and new techniques for insert bit
Gauge Structure
Multiple gague 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 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 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.


Tricone bit is Widely used in borehole water well drilling,oil,gas well and mining projects.It mainly divided into steel tooth and TCI,diameter from 3 inch to 36 inch.


Packaging & Shipping


Packaging: In wooden case and be packaged according to customer requirements.

Shipping: We will issue the goods within 7 to 30 days after you place your order.
