Selecting the right machine depends on the project's specific requirements. Key technical specifications to consider include:

• Thrust and Pullback Force: Measured in kilonewtons (kN) or tons, this determines the machine's power to push the drill string forward and pull the pipe/cable back through the bore. Higher force is needed for longer distances and harder ground conditions.

• Maximum Drilling Distance and Diameter: This indicates the machine's capability to create bores of a certain length and width.

• Engine Power: The horsepower or kilowatts (kW) of the engine, which is a direct indicator of the machine's overall performance.

• Ground Conditions: The machine's ability to operate effectively in various soil types, from soft ground to hard rock.
