Description

The system consists of two primary components designed to work together to initiate the bore and guide the pilot string:

Design: A streamlined, solid steel head with a tapered, conical nose.
Cutting Action: Primarily a ploughing and pushing action. It efficiently displaces soft soil (like clay, loam, and sand) to form the initial pilot bore, requiring less torque than traditional rotary cutters.
Steering Mechanism: Features an asymmetrical front face or strategically placed fluid ports (jets) that allow the operator to change direction by holding the tool face steady while pushing.

Design: A flat, robust circular or rectangular plate that acts as the transition piece between the Pilot Shoe and the first drill rod or housing.
Connection Point: It features the precise API or OEM Thread on the rear to connect to the drill string and a robust connection point on the front to secure the Pilot Shoe.
Role in Steering: Ensures the Pilot Shoe is held rigid and square to the drill string, providing a consistent platform for directional adjustments.
