Double-head drilling method

The double-head drilling method is a drilling system that works with separately coordinated drilling tools on a rotary drilling drive, a percussion drilling drive or a rotary percussion drilling drive. As a rule, the drilling method between outer and inner pipes rotates in opposite directions.

  • Outer tubes smooth rods for rotary drilling
  • Inner tubes with percussion rods
  • Hydraulic hammer drill

Inside pipes are drilled with percussion rods above the hydraulic hammer, which is located above the rotary drive.
