THE DRILLER'S CHOICE

Large ID Ring-Bit Systems

Large Inner-Diameter (LID) ring-bit systems are used with sacrificed casings when there is a requirement to continue the hole after the casing is set.
Such casings are left in the ground for economical reasons, corrosion protection, sealing, or dealing with ground cavities.

Primary applications:
  • Piling with sacrificed casings and rock sockets
  • Geothermal and water wells
  • Surface casings (sealing, dewatering)
