Roller Bit Core Barrel With Helix Flight

A roller bit core barrel with helix flight is a specialized drilling tool used in various industries, particularly in the field of geotechnical and environmental investigations. It consists of a hollow tube, known as the core barrel, which is equipped with a roller bit at the bottom and helix flights along its length. The roller bit helps to crush and break the subsurface formations, while the helix flights aid in extracting the drilled material to the surface. This combination of roller bit and helix flights enables efficient and effective drilling, allowing for the collection of core samples and the exploration of geological formations.
