Product Description

140mm Symmetric Overburden Casing Drilling System for Mining, Well Drilling

Product Description

Working principle:

At clockwise condition, reamer bit expanded to bring the casing tube into hole. After finished, reamer bit closed anticlockwise and then can be lift up by the drilling machines. This casing drilling bit is especially suitable for diameter 114-273mm.


The Overburden Casing Drilling - the ultimate solution for enhanced drilling performance and efficiency. With its advanced features and innovative design, this product is optimized to tackle the toughest drilling challenges.

One of the highlights of this drilling system is its hardening treatment. The casing undergoes a specialized hardening process, resulting in superior durability and wear resistance. This ensures a longer lifespan, allowing for extended drilling operations without compromising on performance.

 

 

Features:
1. Hardening treatment of the part's surface with longer operating life and excellent anti-wear properties.
2. Structural Optimization, improving the structural strength and ease of operation
3. Superior Performance, higher drilling speed with stable and reliable performance
