Concentric Casing System with Precision Ring Bits

Changsha Tianhe Drilling Tools and Machinery Co., Ltd. proudly presents its robust concentric casing system with precision ring bits, engineered for the most challenging geological conditions such as pebble beds, fissures, dry stone layers, boulders, and construction backfield waste. This dynamic system empowers you to drill at any angle while maintaining extreme precision and high straightness, with an impressive maximum hole diameter capability of 1550 mm.

Insight into the 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
