Specifications and Product Details:

Steel tooth tricone bit

Adopt high strength and high toughness carbide insert is improved with new formulas and decreased the breakage rate
The durability of premium tungsten carbide insert is improved with new formulas and new techniques for insert bit
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.

Gauge structure

Multiple gauge protection with trimmers on the heel of cone, tungsten carbide inserts and hard facing on the shirttail increases gauge 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 lubrication

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 lubricating reliability.

Product Application

It is suitable for various formations, and achieves high Rpm under low to medium WOB application. Limestone, dolomite, chert, firm sandstone, firm anhydrite and so on..
