PRING E

Ring Bit Casing System – PRING-E

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-E system is the economical version of the Pneumec Ring Bit System.  It uses a conventional casing shoe without attached to the ring.  Once the hole is completed the driver bit can be pulled out of the hole, leaving the casing and the ring down in the hole.  If the casing is to be recovered, the ring will still be left down in the hole as it is not attached to the casing shoe.
