Product Description

Milled Tooth Tri-cone Bit

 

Cutting Structure

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

The wear-resistance of teeth is enhanced with premium tungsten carbide hardfacing on the tooth surfaces.

Bearing Structure

Nonsealed roller bearing. Drilling fluid can enter the bearing directly for cooling; Balls lock the cone which reduces the 

probability of cone ropping to minimum.

Product Application

It is suitable for the shallow well, water well and geothermal well.
