203mm DHD350 Shank DTH Bit (8 Inch) for Mass Excavation | MSD

Features & Benefits

• Powerful DHD350 Shank Interface: Features the robust DHD350 shank, designed for more powerful 5-inch class DTH Hammers, ensuring efficient energy transfer and reliability in demanding applications.

• Maximum Material Removal: The large 203mm (8") diameter is designed for mass excavation, maximizing the volume of rock broken per blast and significantly reducing the number of holes required.

• Superior Hole Straightness: The concave face design is critical for maintaining directional control with large diameter bits, ensuring straight, high-quality holes for effective blasting.

• Heavy-Duty Spherical Buttons: Equipped with large, tough spherical tungsten carbide buttons, engineered to withstand the immense impact forces of large-scale drilling.

Recommended Applications

• Large-Scale Mining and Quarrying: The definitive choice for production drilling in major open-pit mines and quarries where high-volume blasting is the goal.

• Mass Excavation and Major Infrastructure: The go-to tool for the most demanding civil engineering projects, such as dam construction and major highway projects.

• Deep, Large-Diameter Boreholes: A reliable choice for deep geothermal wells and other applications requiring large, straight holes.
