single bits 1.high temperature and wear resistance 2.IADC code suitable for different formation 3.best price,high quality

1.our company had done this business for many years and won a good reputaion for our top quality products and excenllent service.

2.we produce the drill bits according to our customers requirements strickly with advanced equipment to make the quality perfect.(extend work life,wear resistance,self-sharpening....)

3.if you want to get more details,pls don't hesitate to contact me.

1. Cutting structure 

In response to the characteristics that inserts in different areas on the cone have different cutting 

actions, conical inserts are placed in permanent contact area and wedge inserts are placed in 

alternative contact area so that the drilling efficiency is greatly improved. Wear resistance of cutting

 structure is enhanced by setting diamond inserts in the permanent contact area of the cone where

 inserts are severely worn. Tungsten carbide inserts are placed on cone top face to protect cone 

body from abrasive erosion.

2. Gauge Structure 

With active cutting gauge protection inserts on bit body, the bit has good gauge protection inserts 

on bit body, the bit has good gauge protection and up drill capability 

3. Bearing Structure

High precision journal bearing, Ball lock the cone. Hardface heard bearing surface. Cone bearing

inlaid with friction reducing alloy. Abrasion resistance and seizure resistance of the bearing are improved. Compared 

with three cone bit, the leg bearing is bigger, so it can receive higher WOB and high reliability.

4. Hydraulic Design

Small angled water course design increased the shirttail thickness and can effectively prevent the

 watercourse erosion. Optirnized hydraulics structure improves the clearing capability and increases ROP.

5. Product Application 

It is suitable for sidetracking, deep well drilling and old well repairing.
