The Concentric/Symmetric casing system product line includes the enhanced system with striking faces and extracting highly resistant.
In horizontal drilling, the friction between the soil and the casing can become very important and Symmetrix reinforced bits are designed to resist abrasion under these conditions.
These systems are targeted for drilling in leading which the cutting ring is recovered for reuse. They can also be used for drilling deep holes vertical when it is not necessary to use an inside diameter of annular cutting important.
Reinforced systems are available for tubing sizes ranging between 140 mm and 1220 mm (5 1/ 2 "and 48").
