Landfill Drilling Internal Casing Cutter / Integral Operation Pwt Casing

Internal Casing CutterDetails: 

Casing System is an ingeniously designed eccentric drilling system which consists of a pilot bit and reamer “wing”. The pilot bit protrudes beneath the casing pipe and, as the drill rotates, a specially designed “wing” folds out and acts as a reamer. This creates the space for the casing pipe to advance. Once through the overburden, Odex makes a socket in the bedrock allowing the casing to be fixed in place. Then, by simply reversing the drilling rotation, the wing retracts into the pilot bit and the whole drill string can be removed from the hole leaving the casing pipe in place.

Internal Casing Cutter Features:    

1. Cases borehole as borehole advances.                               
2. Helps reduce drilling cost by saving rod and casing handling.         
3. Can be used with Rock Bot or TC. Drag Bit.         
4. Long Casing Shoe life as it is always reaming and never drilling alone.      
5. Special flushing ports in the body ensure that the casing bit is adequately flushed.
