Product Description
Product Overview
Geological surface set diamond reaming shells with core bits are precision drilling tools designed for geological exploration and core sampling applications. These professional-grade components ensure accurate hole sizing and enhanced drilling stability.
Key Functions & Applications
Surface set reaming shells feature natural diamonds (typically 20/30SPC size) mounted externally on the shell surface. The optimized waterway design ensures smooth rock cutting and efficient flushing during operation.
Reaming shells connect drill bits with core barrels, serving two critical functions: reaming holes to precise constant diameters for proper core barrel clearance, and stabilizing the drill bit assembly during operation.
