Introduction

Definition and Overview

This type of drilling tool is characterized by its cutting structure which is made up of multiple steel teeth that are milled directly into the cone. These teeth are hard-faced with tungsten carbide or similar materials to increase their durability and wear resistance. The primary function of these tools is to crush and scrape rock at the bottom of the wellbore as the drill string rotates. They are particularly effective in softer geological formations where the interlocking teeth can easily penetrate the rock.
