Product Description

Symmetric 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 a full face head design which significantly improves the penetration rate and
hole straightness of drilling. The internal flushing grooves together with the built-in casing
shoes gives a good seal to the bottom of the drilling hole, and thus minimising the
disruption of the surrounding of the drill hole.
