Ring bit system
W-Rex
When drilling down casing, either for foundation work, as piles, or as part of a well when sealing of the overburden,the Wassara designed W-Rex Ring bit system is the system to use.
With a pilot bit that is made of quality parts to ensures long service life and a ring set that should reach the depth target with concern taken to the inserts as well as design of the coupling between the casing shoe and the ring bit.
When drilling down a casing that is to be used as a pile the system is not designed for drill trough with the same size hammer. If one needs to drill through a smaller hammer size need to be used. Here W-Rex Pile should be used.
When used for wells, water wells or Geo energy hole it is needed to continue through the ring bit with the same hammer size, W-Rex Well should be used.
Common for the W-Rex ring bit system is that they are designed to match dimensions of the Wassara water powered hammers. Here the pilot shank matches the piston in the hammer which creates optimal conditions for long and problem free operations.
W-Rex is the preferred casing system for Wassara drilling.
