Concentric Casing System with Ring Bits: Precision for Every Geological Challenge

Changsha Tianhe Drilling Tools and Machinery Co., Ltd. proudly presents the concentric casing system with ring bits, designed to conquer the toughest geological challenges, including pebble, fissure, dry stone, boulder, and construction backfield waste. This system facilitates drilling at various angles while achieving remarkable straightness, accommodating a maximum hole diameter of 1550 mm with unparalleled precision.

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
