Faqs:
  • What is drilling with ODEX?
    Drilling with ODEX involves using an air-operated down-the-hole hammer to ream the bottom of the casing with a swing-out eccentric bit, allowing cuttings to emerge via the casing annulus for quick removal.
  • What PSI is required for air tools?
    Most air tools require 70-90 PSI, with 90 PSI being easily achievable by light-to-medium duty air compressors. Insufficient air volume can cause improper tool function.
  • How does a casing advancer work?
    The Casing Advancer allows drilling and casing to be carried out simultaneously as one integral operation, eliminating the need to drill and then ream the casing separately.
