Single tube bit
A single tube bit is a drilling tool designed for core drilling operations. It features a single cylindrical barrel that houses the core sample as drilling progresses. Typically used in shallow drilling projects, the single tube bit helps to collect undisturbed core samples, offering a simple yet effective solution for exploration or geotechnical surveys. The design ensures smooth cutting and minimal core disturbance, making it ideal for softer formations.
