PRING XD

Ring Bit Casing System – PRING-XD

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-XD system has a completely full face concentric design consisting of a driver bit, a ring assembly with the ring and casing shoe attached together.  It is purposely designed so that the ring assembly can be reused.  It also allows a larger pass through diameter through the ring, and if required a button bit can pass through the ring and continue to drill into the rock socket.
