Casing Advancer
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.
Key:
1. Standard Casing,
2. Rod Entry Guide Sub,
3. Body,
4. Hi-tensile Drive Pin,
5. Seal,
6. Advancer Casing Shoe,
7. Diamond Casing Bit
8. Tricone Rock drill bit
The integral operation makes the Casing Advancer eminently suitable for drilling through overburden or sands and gravels. It is also particularly suitable for Landfill Drilling applications.
Casing Advancer – Outstanding Features:
● Cases borehole as borehole advances
● Helps reduce drilling cost by saving rod and casing handling.
● Can be used with Rock Bit or T.C. Drag Bit.
● Long Casing Shoe life as it is always reaming and never drilling
alone.
● Special flushing ports in the body ensure that the casing bit is
adequately flushed.
● Uses conventional Right Hand threaded Drill Rods and Casing.
● Suitable for Air, Water or Mud Flush.
● Manufactured from high quality materials.
