Products Description LEANOMS
In top hammer rock drilling, Extension Drill Rod is also known as hydraulic drill rod or high duty drill rod. The Rock Drill Extension Rod is attached to the shank adapter and drill bit through the threads on both sides of the rod body.
And delivers the hydraulic rock drill's impact energy and torque to the drill bit for rock drilling.
The thread system is used by the LEANOMS Drill Extension Rod. Drilling precision may be enhanced even further by utilizing this as the first rod in a standard drill string. Furthermore, because this is a speed rod design, it will produce straighter holes and a 10% greater penetration rate in favorable rock conditions than a rod and coupling sleeve combo system.
LEANOMS OEM High Carbon Steel Materials Drill Extension Rod Length: 600mm to 6400mm Top hammer drilling equipment for long holes, including drill bits, coupling sleeves, extension drifter rods, and shank adapters. High penetration rates, straight, high-quality drill holes, and low overall production costs are all features of our drilling system.
Tools for drilling deep holes
MF-rods, Drill Extension Rod, coupling sleeves, shank adapters, and drill bits make up a full selection of top hammer tools for long hole drilling. Our drilling system provides high penetration rates, straight, high-quality drill holes, and low overall production costs.
It is well known that that the performance of the material can only be played successfully after going through heat treatment to release its fullest potential; so, both the material choice and the heat treatment procedure are equally crucial.
Products introduction LEANOMS
Purpose:
The T38 extension rod is designed to extend the reach of the drilling tool, connecting the rock drill to the drill bit. Its primary purpose is to facilitate efficient rock penetration and drilling in various geological conditions.
Thread Type:
The T38 extension rod features a specific thread type known as T38. This threaded connection ensures compatibility with rock drills and drill bits designed to use the T38 thread configuration.
Material:
The extension rod is constructed from high-strength alloy steel, known for its durability and resistance to wear and tear. The choice of materials is crucial to withstand the demanding conditions of rock drilling.
Length and Diameter:
The T38 Rock Drill Extension Rod Drill Rod Pipe comes in various lengths to accommodate different drilling requirements. The diameter is designed to match the size of the drill string and rock drilling equipment.
Hexagonal or Round Shape:
T38 Rock Drill Extension Rod Drill Rod Pipe may have a hexagonal or round cross-section. The hexagonal shape provides a secure grip, facilitating easy installation and removal during drilling operations.
Tapered Design:
Many T38 Rock Drill Extension Rod Drill Rod Pipe have a tapered design, with one end having a larger diameter than the other. This taper aids in easy coupling and decoupling of rods during the drilling process.
Applications:
T38 Rock Drill Extension Rod Drill Rod Pipe is suitable for a range of drilling applications, including surface mining, quarrying, and construction. They are versatile and adaptable to different geological conditions.
Cooling Channels (Optional):
Some T38 Rock Drill Extension Rod Drill Rod Pipe may come with internal cooling channels. These channels facilitate the circulation of air or water, helping to cool the drill bit during extended drilling sessions.
Products Description LEANOMS
Here are common rock types on which the T38 Rock Drill Extension Rod can be effectively used:
Hard Rock:
T38 extension rods are particularly well-suited for drilling in hard rock formations. These may include granite, basalt, and other igneous rocks known for their high density and resistance to abrasion.
Metamorphic Rock:
Metamorphic rocks, such as marble, slate, and schist, are often encountered in geological formations. The T38 extension rod's robust design allows for efficient drilling in these altered rocks.
Sedimentary Rock:
Sedimentary rocks, like limestone, sandstone, and shale, can vary in hardness and composition. The T38 extension rod is versatile enough to handle drilling in different types of sedimentary formations.
Volcanic Rock:
Volcanic rocks, including andesite and tuff, are commonly found in volcanic regions. The T38 extension rod is suitable for penetrating these rocks, which may exhibit varying levels of hardness.
Granitic Gneiss:
Granitic gneiss, a metamorphic rock with a granitic composition, can present challenges due to its variable hardness. The T38 extension rod is effective in drilling through this type of rock.
Quartzite:
Quartzite, a hard and durable metamorphic rock formed from sandstone, can be successfully drilled using the T38 extension rod. The tool's strength and compatibility with hard rocks make it suitable for this application.
Diorite:
Diorite is an intrusive igneous rock with a composition similar to granite but with a different mineral makeup. The T38 extension rod is capable of drilling through diorite formations.
Phyllite:
Phyllite, a low-grade metamorphic rock with a distinct foliation, can be encountered in certain geological settings. The T38 extension rod can be employed to drill through phyllite formations.
Breccia:
Breccia, a rock composed of broken fragments cemented together, may require effective drilling tools for exploration or extraction. The T38 extension rod is suitable for such applications.
Dolomite:
Dolomite, a sedimentary rock containing the mineral dolomite (calcium magnesium carbonate), can be encountered in various geological contexts. The T38 extension rod is applicable for drilling in dolomitic formations.
