Concentric Casing System with Ring Bits: Precision and Versatility for Tough Conditions

Changsha Tianhe Drilling Tools and Machinery Co., Ltd. proudly presents our concentric casing system with ring bits, engineered for excellence in challenging geological conditions, including pebble, fissure, dry stone, boulder, and construction backfield waste. This sophisticated system enables precision drilling at various angles while ensuring exceptional straightness, accommodating a maximum hole diameter of 1550 mm with ease.

Drilling Process Overview:

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
