Concentric Casing System with Ring Bits: Precision and Power Combined

Discover the concentric casing system with ring bits from Changsha Tianhe Drilling Tools and Machinery Co., Ltd., engineered to excel in challenging geological conditions such as pebble, fissure, dry stone, boulder, and construction backfield waste. This advanced system not only allows for drilling at various angles but also maintains exceptional straightness, achieving a maximum hole diameter of 1550 mm with unparalleled precision.

Drilling Process: A Seamless Blend of Innovation and Expertise

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
