Ordering Information
To place an order, please provide the following specifications:
- Casing Tube OD & ID
- Reamer Bit Diameter
- Minimal Casing Shoe ID
- Hammer Shank Style
Working Principle
During clockwise rotation, the reamer bit expands to advance the casing tube into the hole. Upon completion, the reamer bit closes during anticlockwise rotation, allowing retrieval by drilling machines. This casing drilling bit is specifically designed for diameters ranging from 114mm to 273mm.
Application Range
Ideal for various drilling applications including:
- Water wells
- Geothermal wells
- Short micro piles
- Medium mini-type grouting holes for building, dam, and harbor projects
Technical Reference
Overburden Drilling Systems
These systems are engineered for cost-effective drilling with simultaneous casing advancement. Overburden soil typically contains sand, rocks, clay, and stones, lacking the organic material found in topsoil.
