A Buying Guide For Pre-owned Directional Drilling Reamers

By Thomas Cox


HDD tools are usually expensive. Therefore, buying used tools is cost-effective provided you do your homework. If you wish to buy a new machine, you must have enough cash for the purchase. If not, used machines are the next best option. However, contractors should be cautious when buying these tools. This is because some sellers may provide tools that are worn out. This will thus be a waste of time and money. That is why it is crucial to inspect the Directional Drilling Reamers before purchasing them. Check if the size is right because this is something most contractors forget. The buying guide below will be of great help during your search.

You should consult an experienced person before you set out for shopping Check the drill pipe to make sure it is in good condition. Checking whether the thread profile is worn out is paramount. This will prevent you from buying equipment that is damaged or worn out. Thus, make sure you have inspected the rod to avoid losing lots of money and time.

Checking the hydraulics system of the machine is also critical. You must make sure that the pressure of the tool is set within the recommended specifications. Do not ignore this step like most contractors because it is essential. This is because you may test the device and think that it is okay only to find that the pressure is low. Low pressure will cause problems during your project. Thus, you will be forced to repair the equipment.

Check the rack as well. Before you purchase the tool, make sure you have checked its rack and pinion. The carriage usually runs on the rack when it is being used. Hence, this system wears out after some time. Since there are different models, some racks will become damaged faster than others. Thus, buy a machine only after checking the tool critically.

Another critical part to check is the makeup system. This system can also be called a wrench or vice. The pipes should be screwed together when you are drilling out. It is also essential to check if the tool is working well when you are pulling back. You should test the pieces to check if they are moving as they are supposed to.

Take the time to check the reamer and drill head as well. Adapters are usually present at the tail of the housing or at the front part of the machine. This makes it easy to change the threads and use the equipment for various drill setups. Avoid tools that have adapters that have been welded in place.

The rock tooling is also critical to check before buying the used tools. Usually, the roller cones on the reamer should be tight when turning. The side to side movement will tell you whether the bearings are broken. Replacing the cones can be very costly and time-consuming.

Ensure that you are careful when looking for these tools because making a mistake will cost you dearly. Do not buy any equipment from a dealer that does not allow you to visit his shop. You should check out the shop and determine whether the dealer is reliable.
