Product Description
Super Jaws Overburden Drilling Systems
The Symmetric - Concentric drilling system is designed to drill and case a hole simultaneously through unstable ground conditions. The driver bit incorporated with a satisficial ring or reusable ring makes a full face head design which significantly improves the penetration rate and hole straightness of drilling. The internal flushing grooves together with the built-in casing shoes gives a good seal to the button of the drilling hole, and thus minimizing the disruption of the surrounding of the drill hole.
Super jaws is especially popular in micro-piling, tie-back work, or overburden systems where the casing is recovered, or in deep overburden areas where high amounts of friction build up on the outside of the casing.
The Super Jaws Overburden Bit can be used with different casing wall thicknesses and produces outstanding results in all formations.
