Why You Should Consider Purchasing a Second-Hand Horizontal Drilling Machine

Horizontal Drilling Machine


When it comes to underground utility installations, the horizontal drilling machine has revolutionized the industry. This article aims to shed light on why purchasing a second-hand horizontal drilling machine could be a wise investment for contractors and businesses alike.

What is a Horizontal Drilling Machine?

A horizontal drilling machine, also known as a Horizontal Directional Drilling (HDD) machine, is a specialized piece of equipment used for installing underground utilities like water, gas, and electrical lines. It offers a trenchless method of installation, which means minimal surface disturbance and quicker completion times.

The Three-Step Process of Horizontal Drilling

Pilot Hole

The first step in the HDD process is drilling a pilot hole. The drill string is formed by linking drill rods together to advance the drill bit. A transmitter receiver system traces the location of the signal exerted by the sonde housing, ensuring precise drilling.


The second step involves enlarging the pilot hole using a reamer. The size of the reamer depends on the desired diameter and soil conditions. Drilling fluid, often mixed with additives like polymers, is pumped through the drill pipe to stabilize the hole and facilitate drilling.

Pipe Pullback

The final step is the installation of the utility pipe. A reamer is connected to the drill pipe and pulled back towards the entry point, installing the pipeline in the process. Drilling fluid is used for lubrication during this stage.

Why Go for a Second-Hand Machine?


Purchasing a brand-new horizontal drilling machine can be a significant investment. Second-hand models offer a more budget-friendly alternative without compromising on functionality.

Quick ROI

A second-hand machine can provide a quicker return on investment (ROI) as the initial cost is lower. This is particularly beneficial for smaller contractors or those just introducing horizontal drilling into their service offerings.

Availability of Spare Parts

Most second-hand machines are well-known models for which spare parts are readily available. This ensures that maintenance and repairs can be carried out efficiently.

Proven Reliability

A used machine has a track record, allowing you to gauge its reliability and performance based on its service history.

Maintenance Tips for Second-Hand HDD Machines

  • Daily Checks: Before starting the machine, perform a thorough check to detect any issues from previous usage.

  • Lubrication: Proper lubrication is essential for the longevity of the machine.

  • End-of-Day Cleanup: Always clean the machine at the end of the day to eliminate blockages and identify any leaks.

  1. How much does a horizontal directional machine cost?
  • The cost varies depending on the model and condition, from 30000 USD to 500000USD. Second-hand machines are generally more affordable.

           2. How does horizontal drilling work?

  • It involves a three-step process: drilling a pilot hole, enlarging it, and then installing the utility pipe.

          3. How far can horizontal drilling go?

  • The distance depends on the machine’s capabilities and the project requirements.


Purchasing a second-hand horizontal drilling machine offers various advantages, including cost-effectiveness, quick ROI, and proven reliability. With proper maintenance, a second-hand machine can serve you well, making it a wise investment for any contractor or business involved in underground utility installations.
