THE DRILLER'S CHOICE

Drill-Through Systems

Drill-through ring-bit systems combine conventional rock-bit and casing-advancing systems.

Overburden can be drilled with ring-bit set, and then the pilot bit is unlocked from the ring-bit to drill a rock socket without the need to change tools.

Primary applications:
  • Anchoring applications
  • End-bearing piles with rock socket
