Sampling cones are specialized tools used in geotechnical and environmental drilling to gather soil or sediment samples during various testing procedures.

These cones are typically attached to drilling equipment, such as cone penetration testing (CPT) or standard penetration testing (SPT) rigs, and are pushed or driven into the ground to collect samples at specific depths.

The main purpose of sampling cones is to retrieve representative soil or sediment samples for analysis, providing valuable information about the subsurface conditions and properties.
