Core Barrel with Cross Cutter

Core Barrel with Cross Cutter

Categories: ,

Description

The Core Barrel with Cross Cutter is a specialized drilling tool designed for breaking and removing rock cores in fractured rock formations, boulder layers, and hard ground conditions. The cross-cutting structure efficiently fractures the remaining rock core after initial coring, allowing easier extraction and improving overall drilling productivity.
Manufactured from high-strength wear-resistant steel, the tool features a reinforced cutting ring, heavy-duty wear protection, and premium bullet teeth for maximum durability and performance. It is widely used in foundation piling, bridge construction, marine projects, and deep foundation drilling applications.
