FAQ:
Q1 How many drilling rods are used for a typical drill string?
A: 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.
Q2 What are the threads on drilling rods called?
A: The threaded ends of drilling rods that connect them together are called API threads. This refers to the American Petroleum Institute standard thread specifications used widely in oil & gas and mining industries.
Q3: What thread class do drilling rods commonly use?
A: The most common API thread class used for drilling rods is 8 Round, or 8Rd. This refers to threads with 8 threads per inch and rounded (as opposed to sharp creased) thread profiles for strength.
Q4: How are drilling rods connected together?
A: 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. Left hand threads are used on the bottom end.
Q5: What tool is used to connect drilling rods?
A: 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.
