  • Product Description

The Challenge: Drilling in Difficult Ground

Drilling through loose overburden like sand, gravel, or backfill often leads to collapsing holes, stuck equipment, and significant project delays. In fractured or weathered rock, borehole integrity is constantly at risk, making it nearly impossible to achieve a clean, stable hole for piling or anchoring. These challenging ground conditions demand more than just a standard drill bit—they require a complete engineered system.

Our Solution: Simultaneous Drilling and Casing

MSD's Concentric Casing System is the definitive solution to these challenges. This advanced system features a pilot bit and a ring bit that work in unison. As the pilot bit drills the center of the hole, the ring bit simultaneously expands the hole to a larger diameter, allowing the 127mm steel casing to advance down with the drill string. This innovative process drills and cases the hole at the same time, completely securing the borehole wall from the moment drilling begins.

Key Features and Advantages

  • Guaranteed Borehole Integrity: By casing the hole as it is drilled, this system completely eliminates the risk of hole collapse, ensuring a clean and stable 5-inch borehole.

  • Exceptional Hole Straightness: The concentric design provides superior guidance, delivering perfectly straight holes that are critical for deep water wells and geothermal loops.

  • Optimized for DHD3.5 Hammers: The pilot bit is designed with a DHD3.5 shank, ensuring perfect compatibility and efficient energy transfer from one of the industry's most reliable 3.5-inch DTH Hammers.

  • System Reusability: After reaching the desired depth into bedrock, the pilot bit is easily retracted through the casing for use on the next hole, making the system a highly cost-effective investment.

Primary Applications

  • Water Well Casing: The ideal application for setting the surface casing for 5-inch water wells, ensuring a secure and stable well start through any overburden.

  • Geothermal Boreholes: A perfect tool for drilling and casing geothermal loops, especially in residential or commercial projects with difficult ground conditions.

  • Foundation Piling: A reliable system for creating 127mm foundation piles for buildings and other structures.
