Concentric Casing System with Ring Bits 

Changsha Tianhe Drilling Tools and Machinery Co., Ltd. offers a concentric casing system with ring bits that is ideal for challenging geological conditions like pebble, fissure, dry stone, boulder, and construction backfield waste. This system allows drilling at various angles while maintaining high straightness, with a 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
