Frequently Asked Questions
What is ODEX drilling?
ODEX is an adaptation of the air-operated down-the-hole hammer that uses a swing-out eccentric bit to ream the bottom of the casing, allowing rapid removal of cuttings through the drive sub and casing annulus.
How much PSI do I need for air tools?
Most air tools require between 70 and 90 PSI. Always ensure your compressor supplies adequate air volume for proper tool operation.
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 for separate drilling and casing installation steps.
