Product Description
Tungsten Carbide Conical Inserts for DTH Drilling
Tungsten carbide conical inserts are engineered for medium and low pressure Down-The-Hole (DTH) drilling applications in tough hard rock formations. These industrial-grade carbide buttons are specifically designed for shield tunneling boring machine heads, where they provide exceptional wear resistance and impact durability.
Application Overview
Typically, shield machine heads are equipped with 30-40 units or more of these tungsten carbide inserts, depending on the specific equipment requirements. The inserts are bolted and can be conveniently replaced from the soil backroom behind the machine head, ensuring minimal downtime during operations.
These conical inserts operate in complex underground environments including tunnel construction, subway projects, and other infrastructure developments with variable geological conditions. They withstand high-power equipment forces including propulsion and shear forces, requiring superior impact resistance and wear performance.
