Rotary Rock Drilling Tricone Drill Bit with Open Bearing Steel Tooth Forging Type

Introduction

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

Non-sealed roller bearing. Drilling fluid can enter the bearing directly for cooling; Balls lock the cone which reduces the probability of cone dropping to minimum.

Product Application

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