Concentric Slide Block Casing Drilling System

Our concentric casing system with blocks is specifically designed for drilling in soft and unstable formations, making it ideal for applications such as geothermal wells, water wells, small-to-medium-sized grouting holes, and micro-piling projects.

●
Tailored for Soft Formations: Designed to excel in high mud content and formations with abundant floating rocks.
●
High-Performance Materials: Manufactured using specialized 25Si2MnCrNi2MoV steel. Blocks are heat-treated to HRC42-45 for extended lifespan.
●
Simplified Operation: Precision-engineered for quick tool replacement and maximum work efficiency.
