The STM-300 drill head is designed to accommodate drill rods with an inner diameter of 3 inches (76.2 mm). It is often used in exploration drilling where a smaller core size is required for more precise and detailed sampling.

This drill head is equipped with a robust clamping mechanism that securely holds the drill rods in place during the drilling process. It allows for efficient transmission of rotation to the drill bit, facilitating penetration into the rock.

The STM-300 drill head is also designed to be compatible with other components and accessories specific to the STM-300 drilling system, allowing for seamless integration into existing drilling configurations.
