Product Description

Concentric/Symmetric Slide Block Casing Drilling Assembly

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

Key Features

01 Tailored for Soft Formations: Designed to excel in soft formations, including high mud content and floating rocks.

02 High-Performance Materials: Manufactured using 25Si2MnCrNi2MoV. Blocks undergo heat treatment to reach HRC42-45 hardness.

03 Simplified Operation: Precision-engineered for rapid tool replacement and boosted workflow efficiency.
