Cutting structure

1.Adopt high strength and high toughness carbide teeth, enhanced the shock resistance , decreased the breakage rate .

2.The durability of premium tungsten carbide insert is improved with new formulas and new techniques for insert bit.

3. Reasonable design of rows of tooth per cutter,number of tooth,toothy height,and the particular appearance of the carbide gear , greatly enhanced the cutting ability and speed.

Guage structure

Multiple guage protethion with trimmers on the heel of cine,tungsten carbide inserts and hard facing on the shirttal increases guage holding capability and bearing life.

Bearing Structure

High precision roller bearing with two thrust faces. Ball lock the cone.Thrust faces hardface with wear resistant alloy. Abrasion resistance and seizure resistance of the bearing are improved.

Seal and lubracation

Premium O-ring,optimal.Seal compression and curred seal structure can enhance the seal performance.The compensator system and advanced grease can greatly increase the lubricaing reliability.

Product Application

It is suitable for various formations, and achieves high RPM under low to medium WOB application.
