THE DRILLER'S CHOICE

Horizontal Ring-Bit Systems

Horizontal ring-bit systems are made for horizontal drilling of utility lines. High-friction casings call for a heavy duty ring-bit system.

Drilling under roads and railways requires advanced air control. Thanks to a reliable design, Mincon’s ring-bit system can be used over and over.

Primary applications:
  • Horizontal drilling of utility lines
  • Road and railway underpasses
  • Replacing of concrete culverts
  • HDD surface casings
  • All break through drilling
