RFQ:
1. What is odex drilling?
ODEX is an adaptation of the air-operated down-the-hole hammer. It uses a swing-out eccentric bit to ream the bottom of the casing. Cuttings blow up through the drive sub and casing annulus to a swivel conducting them to a sample collector or onto the ground. Rapid removal of cuttings.

2. How much PSI do I need for air tools?
between 70 and 90 PSI
Most air tools require between 70 and 90 PSI. Any light-to-medium-duty air compressor can easily handle 90 PSI, but you always want the compressor to supply more flow than needed. Pro Tip: Always respect a PSI rating. If you don't supply enough air volume, the tool won't operate correctly.

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.
