Product Description
T45 extension rod drill steel is a very common rock drill rod, it can be widely used in open-pit bench drilling and underground production drilling.
T45 drill extension rod is a vital tool in top hammer drilling, primarily used for deep hole drilling. When drilling at greater depths, the T45 extension rod extends the effective length of the drill string, allowing the drill bit to reach deeper areas. It proves especially useful when encountering hard rock layers or obstacles during drilling. The additional length provided by the T45 extension rod helps the drill button bit to penetrate more effectively or maintain a stable drilling process.
In challenging work environments, such as narrow or complex spaces, the T45 extension rod increases operational flexibility, allowing for more precise control over the drilling process.
The standard length of T45 extension rods ranges from 1.5 meters to 6 meters, with commonly available lengths including 10 inches, 12 inches, and 14 inches. Litian Rock Tools can customize the length of the extension rod to meet specific project requirements.
Whether for deep hole drilling, overcoming tough rock formations, or enhancing flexibility in tight spaces, the T45 extension rod is designed to improve efficiency and precision in your drilling operations.
