Tapered drill rods are commonly used for shallow hole drilling operations using small pneumatic rock drills or hydraulic rock drills. Usually, the rods are made of H22 and H25 hexagonal hollow drill steel. These rods are designed to be used with taper drill bits for rock drilling. They are commonly applied in quarries, coal mines, roadbeds, construction and other fields.
The most common taper angles used for tapered drill rods are 7°, 11° and 12°. These taper angles are used to match with the tapered drill bits for rock drilling. The selection of the taper angle will depend on the type of rock or material being drilled, as well as the drilling environment.
Workmanship and Durability of Minetech Taper Rods
At Minetech, we take pride in our superior workmanship when it comes to manufacturing taper rods. Our taper rods undergo a carburize treatment, ensuring a high level of durability for a long-lasting performance.
Toughness and Endurance of Minetech Tapered Drill Rods
Our tapered drill rods play a critical role in drilling operations, transferring the percussion energy from rock drill to drilling bit and eventually into the hard rock. With the high bending stress that they are subjected to, our drill rods are designed to withstand the toughest drilling conditions. Additionally, our rods are exposed to corrosive water in the flushing hole, but our high-quality materials and manufacturing processes ensure that our rods have a long lifespan.
