Specifications

1. Advantages of our products:

(1) Bits sizes range from 3 7/8” to 26

(2) Covers almost all IADC codes

(3) suitable for sidetracking, deep well drilling and old well repair

(4) drilling formation:medium to hard

(5) antiwear and long lifetime

(6)stocks adequate, time delivery

(7) rich experience in drill bit

(8) good after-sales service

(9) High quality, competitive price

2.The design of the product structure:

(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. Optimized hydraulics structure improves the clearing

capability and increases ROP.

3. Product Application:

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