RFQ:
1. What is drilling with odex?
The air-operated down-the-hole hammer is adapted as ODEX. It reams the bottom of the casing with a swing-out eccentric bit. Cuttings emerge via the casing annulus and drive sub, passing through a swivel and onto the ground or a sample collector. Quick removal of the cuttings.
2. What PSI is required for air tools?
In the range of 70 to 90 PSI
The majority of air tools require 70–90 PSI. Ninety PSI can be easily reached by any light-to-medium duty air compressor, but you should always have the compressor producing more flow than is required. Expert Advice: Never disregard a PSI rating. Insufficient air volume will cause the tool to function improperly.
3. How does a casing advancer Work?
The Casing Advancer has been designed to allow drilling and casing to be carried out at the same time as one integral operation. This feature eliminates the need to drill the large diameter hole with a Rock Bit, pull the drill rod string and Rock Bit from the hole and then ream the casing back into the hole.
