PRING SX

Ring Bit Casing System – PRING-SX

The Pneumec P-RING concentric drilling system is designed to drill and case a hole simultaneously through unstable ground conditions.  The driver bit incorporated with a sacrificial ring or reusable ring makes it a perfect drill with a complete full face that significantly improves the penetration rate and hole straightness.  The internal flushing grooves together with the casing shoes gives a good seal to the bottom of the drilling hole, and thus minimizing the disturbance to the surroundings in certain sensitive ground conditions.

The Pneumec PRING-SX system has a completely full face concentric design consisting of a driver bit, a ring assembly with the ring and casing shoe attached together.  Similar to the PRING-S system, the ring assembly is designed for single use.  However, it has a larger ring ID so that if it is required to drill continuously into the rock socket with a button bit, this is the system to go for.
