Concentric Casing System with Ring Bits

Explore the high-performance concentric casing system with ring bits from Changsha Tianhe Drilling Tools and Machinery Co., Ltd. This system is expertly crafted to tackle demanding geological conditions including pebble, fissure, dry stone, boulder, and construction backfield waste. Capable of drilling at various angles, it ensures exceptional straightness with an impressive maximum hole diameter of 1550 mm.

Drilling process:

1.When drilling starts,the reamer opens

2.When the drilling is finished,reverse the rotation to close the reamer

3.Keep the casing tube left in the hole,or pull out and pour in grout sealing material

4.Use conventional drilling bits to continue the drilling
