T38 MF Drill Rod is a very commonly used rock drilling rod, which can be widely used in bench drilling, production drilling and long-hole drilling.

A drill rod, also known as a drill pipe, is a tubular steel member with threaded connections at both ends. It is a crucial component in drilling operations, especially in the oil and gas industry. The primary purposes of a drill rod are as follows:

1. Connection and Support: The drill rod connects the drilling machinery at the surface to the drill bit at the bottom of the wellbore. It provides a continuous and stable structure that supports the drilling equipment and ensures the smooth operation of the drilling process.
2. Mud Circulation: The drill rod serves as a conduit for the circulation of drilling mud. This mud performs several functions, including cooling and lubricating the drill bit, carrying away drill cuttings from the wellbore, and providing pressure control to prevent the influx of formation fluids into the wellbore.
3. Transmitting Force: The drill rod transmits the rotational force generated by the drilling machinery at the surface to the drill bit. This force is necessary to rotate the bit and enable it to cut through the formation.
4. Withstanding Loads: During drilling, the drill rod must withstand various loads, including the weight of the drill string, the reactive forces generated by the bit cutting into the formation, and the loads created by the circulation of mud.
5. Guiding the Drill Bit: The drill rod also acts as a guide for the drill bit, ensuring it follows the desired path and reaches the target depth or formation.

In summary, the drill rod is a vital component in drilling operations, responsible for connecting the surface equipment to the drill bit, transmitting force and mud, and withstanding various loads and pressures. It plays a crucial role in ensuring the efficient and safe execution of drilling activities.

MF rod, also known as speed drill rod, has a male thread at one end and a female thread at the other end. It can directly connect to the shank adapter without the aid of a coupling sleeve, which eliminates the defect that the equal diameter thread connection is prone to vibration. The quick-change properties of male/female rods improve the overall drilling efficiency. 

As an MF Rod manufacturer, we have two MF rod factories in China. Our MF drill rods are made of high-quality alloy steel and advanced thread manufacturing technology, and have excellent performance in wear resistance and flexibility. We offer speed drill rods with various threads, such as R23 MF drill rod, R32 MF drill rod, R38 MF rod, T35 MF rod, T38 MF drill rod, T45 MF rod, MF rod T51, GT60 MF drill rod, SR35 speed rod, etc.

Specification Of MF Rod

23CrNi3Mo is used for Extension rods, MF-rods, Coupling, Shank adapter etc.

Drill Rod Coupling Sleeve is a sleeve-shaped rock drilling component with internal threads for connecting shank adapter and drill rod, or drill rod and drill rod. We produce and provide three types of drill rod couplings – semi bridge couplings, full bridge couplings, and crossover couplings, which can meet the requirements of all applications.

Standard coupling sleeve

Standard coupling sleeve, also known as semi bridge coupling sleeve, has a section of the bridge without a thread in the middle. The threaded part of the drill pipe cannot be screwed through the bridge part of the coupling, and the end of the thread can closely adhere to the casing bridge zone. Standard coupling sleeve is particularly suitable for high-torque drilling rigs. Most rope thread (R thread) and trapezoidal thread (T thread) coupling sleeves are with half-bridge type. The half-bridge type is by far the most widely used couplings.

Full bridge coupling sleeve

Full bridge coupling sleeve can completely eliminate the looseness of the coupling sleeves along with the threaded connection. It is mainly used in surface mining, with better disassembly characteristics, firmer connections, and almost no clamping situation.

Crossover couplings

Crossover couplings are used to convert different thread types or thread diameter sizes.
