Product Description

Concentric/Symmetric Slide Block Casing Drilling Assembly Bit

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.

Key Features

Tailored for Soft Formations: Designed to excel in soft formations, including those with high mud content and abundant floating rocks.
High-Performance Materials: Manufactured using specialized materials like 25Si2MnCrNi2MoV. Blocks undergo surface treatment to achieve a hardness of HRC42-45 for extended lifespan.
Simplified Operation: Precision-engineered to save time on tool replacement and boost overall work efficiency.
Wear Resistance: Deep heat treatment processing ensures exceptional durability and resistance to wear during heavy-duty operations.

Application Scenarios

The versatility of our Concentric Casing System with Blocks makes them widely applicable across various industries:

Open-pit and Underground Mining
Tunneling and Anchoring Projects
Blast Furnace Tapping & Hydroelectric Projects
Quarrying and Land Preparation
