Drill rod is a tool that connects drill bit and is matched with rock drilling machine to drill in the rock or soil.
Kelleg provides you with high-quality and stable rods. Our drill rods are made of high-strength materials to ensure their durability and stability, making your rock drilling more efficient. We also offer a wide range of sizes and dimensions of drill rods to meet different occasions and needs. When you choose Kelleg rock drill rods, you will have a quality, practical and reliable tool for rock drilling.
Drill rods include light drill rods and heavy drill rods.
Light drill rods include tapered drill rod, shank rod, and integral drill rod.
Tapered drill rod: It is a hexagonal hollow rod with a shank structure. The shank is connected with the rock drilling equipment. The head of the rod is a taper structure that can be connected with a tapered bit.
Shank rod: It is a hexagonal hollow rod with a shank structure. The shank is connected to the rock drilling equipment. The head of the rod is a threaded shape that can be connected with a threaded bit.
Integral drill rod: It is a rock drill tool that combines the shank adapter, shank collar, drill rod, and drill bit as a whole. It is suitable for small diameter shallow holes and is usually used for broken rock, weathered rock, and other soft rock.
Heavy drill rods mainly include drill rods used for drifting and tunneling rigs, benching drilling rigs, and Open-cutting drilling rigs. They are mainly classified as follows:
1. Classification by thread type
There are mainly two types of R-thread and T-thread.
R-thread specifications are R25, R28, R32, R38, etc. The basic dimensions and button profile of the R-thread mainly refer to the industry standard ISO10208.
T-thread specifications are T38, T45, T51, etc. The basic dimensions and button profile of T-thread mainly refer to the corporate standards that are almost the same.
2. According to the internal and external thread form of the drill rod
It mainly includes extension rod and MF rod.
Extension rod: a drill rod with external threads at both ends.
MF rod: a drill rod with external thread at one end and internal thread at the other end.
There are many types of drill rods. In addition to the above classification according to light and heavy drill rods, the connection methods of drill bits and drill rods are also commonly used to classify:
Threaded extension rod
A threaded extension rod is a hollow circular or hollow hexagonal rod with connecting threads at both ends or one end of the rod. It has the advantages of a wide application range, fast drilling speed, low impact energy transmission loss, high rock drilling efficiency, easy realization of mechanized drilling, and improved rock drilling conditions.
Main products: R22, R25, R28, R32, T35, T38, T45, T51
Applications: surface mining, underground mining, roadway excavation, anchoring engineering, blast furnace taphole, tunnel engineering, hydropower engineering, quarrying, and other construction projects.
Tapered drill rod
The tapered drill rod adopts a forged drill shoulder and shanks in connection with the rock drilling machine; in connection with the drill bit, it adopts a cone structure.
Main products: H22, H25
Application: mining, tunneling, anchoring engineering, quarrying, building construction, and other industries.
Length
Light drill rods: 300mm-6000mm(without shank , conventional lengh of shank is 108mm).
Heavy drill rods: 600mm-2000mm(Drill rods less than five meters are available).
The factors affecting the quality stability of drill rods are mainly materials, processes, and equipment.
In drilling, drill rod needs to bear three kinds of stress: axial anxiety, torsional stress, and bending stress.
Factors affecting the fatigue life of drill rods include material, quality of smelting, the surface quality of drill rods, geometric structure, manufacturing process, and rock drilling conditions.
The fatigue fracture of drill rod is characterized by shank shoulder root fracture, the middle fracture of shank shoulder, metallographic organization and microscopic fracture.
The kinds of threaded extension rods are extension rod, light-weight extension rod, drifting and tunneling rod, MF rod and other structural threaded extension rods.
The basic requirements of threaded extension rods are the combination of high fatigue strength and fracture toughness. Good elasticity and wear resistance. Good corrosion resistance. High straightness and rigidity. Good structural design.
