Concentric Super Jaws Casing Drilling System With 4"-12" Hammer Type

Concentric Super Jaw Casing Drilling System With Side Blocks

Product Specification:

The Super Jaws® Overburden Bit is a revolutionary new bit design with wings that extend out larger in diameter than the casing while in the drilling position. The face design of the Super Jaws® Overburden Bit keeps it almost identical with a conventional bit face, allowing for unmatched penetration rates and smooth operation while drilling through overburden, boulders, or bedrock.

When drilling is completed, the bit is simply lifted off bottom, causing the wings to retract back into the guide body. This allows all tooling to be extracted while leaving the casing in place. There is no forward or reverse rotation required, nor any expensive rings left in the hole.
