Australian Made HDD Rock Drill Bits
Built for Faster Penetration in Hard Ground Conditions
When drilling through abrasive ground, standard drilling bits wear quickly and reduce steering accuracy. No Dig Equipment’s Tri-Hawk HDD Rock Drill Bits are purpose-built to deliver exceptional cutting performance, improved steering control and longer service life in challenging ground conditions.
Manufactured in Australia using high-quality materials and premium carbide cutters, our rock drill bits are designed for Horizontal Directional Drilling (HDD) contractors working in shale, limestone, pindan, gravel, cobbles and weathered rock formations.
Whether you’re completing utility installations, pipeline crossings or civil infrastructure projects, our drill bits provide the reliability and durability needed to keep your bore on target.
Independent Cutting Path
The 3 main carbide cutters cut independent paths around the tool’s centerline, achieving an optimum cutting angle, producing a smoother cutting action, and delivering longer bit life.
Cutter #1 initiates the cut
Cutter #2 makes a slightly deeper relief cut just inside the initial cut
Cutter #3 breaks the chip for easy removal.
Field Serviceability
Main carbide cutter punch-out holes are easily accessible, allowing for easy field serviceability.
