Core Barrel with Bullet Teeth

Description

The Core Barrel with Bullet Teeth is a specialized drilling tool designed for penetrating medium to hard rock formations, reinforced concrete, boulders, and weathered rock layers. Equipped with high-performance bullet teeth arranged around a reinforced cutting ring, it efficiently cuts an annular groove that weakens the rock structure, allowing easier core extraction and improved drilling performance. Manufactured from high-strength wear-resistant steel, the core barrel provides exceptional durability, stability, and operational reliability in demanding foundation and piling applications. It is widely used where conventional augers are less effective and precise rock penetration is required.
