  • Welded Casing Shoe: Secures the starter casing, preventing the pilot bit from leading the casing.

  • Hammer Action Mechanism: Efficiently pulls the casing through the borehole.

  • Closed Face Bit Design: Prevents ground infiltration into the casing pipe, ensuring integrity during drilling.

  • Hydraulic Line and Grade Adjustment: Automatically adjusts to maintain precise line and grade, eliminating the need for on-grade jacking pit floors.

  • Adaptive Hammer Force: The hammer's energy adjusts dynamically to optimize the advancement of the casing pipe.

  • Minimized Radial Vibration: Hammer energy is directed straight into the rock via a carbide point, reducing radial vibration for improved performance.

  • Spiral Flush Pilot Bit: Features air channels that direct exhaust air from the hammer across the bit and into the ring bit and casing pipe, preventing ground charging.
