Product Q&A

Q:How many drilling rods are used for a typical drill string?

The number of rods used depends on the depth of the hole, but a general rule of thumb is to use one rod for every 3-5 feet of drill depth or hole depth. Deeper holes require more rods.

Q:How are drilling rods connected together?

Drilling rods are connected end to end using threaded pin and box connections. The box end of one rod screws onto the pin end of the next rod to form a continuous drill string.

Q:What tool is used to connect drilling rods?

A power tong or torque wrench is used to screw drilling rods together. This tool applies precise torque to the connections to prevent cross-threading and ensure sufficient tightness when making up a drill string.

Q:What are the available lengths for the drill rods?

Standard lengths include 0.5m, 1m, 1.5m, 2m, 2.5m, and 3m, with options for customized lengths to meet specific project needs.

Q:What materials are used to manufacture these drill rods?

The drill rods are manufactured using Cr-Mo Steel and 4130 Alloy Steel Tubing, ensuring high strength and durability for demanding drilling conditions.
