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.
