THE DRILLER'S CHOICE

Retrievable Ring-Bit Systems

Retrievable ring-bit systems can be reused several times and are designed so that the casing can always be pulled out after drilling.

A large inner diameter allows for the largest rock socket and installed elements.

Primary applications:
  • In-situ piles (skin friction) where casing is fully retrieved
  • Anchoring applications
  • Pre-drilling/temporary casing applications
  • Energy/water wells where casing is fully removed
