Tapered drill rods are widely used in shallow hole drilling operations carried out using small pneumatic rock drills or hydraulic rock drills. Generally made of H22 and H25 hexagonal hollow drill steel, tapered drill rods need to be connected to the taper drill bit for efficient rock drilling.
These rods are widely used in several fields, including, but not limited to, quarries, coal mines, roadbeds, and construction sites. With conventional taper angles ranging from 7°, 11°, and 12°, the choice of an appropriate angle would depend on the specific needs of the user.
As mentioned earlier, tapered drill rods are made of hexagonal hollow drill steel, specifically H22 and H25. These high-quality materials ensure that the drill rods are durable and reliable in their applications.
Tapered drill rods find extensive use in rock drilling operations, with applications in various fields as follows:
Quarries- for drilling stones, rocks and other geological samples
Coal mines- for drilling holes for mineworkers to carry out their duties
Roadbed construction- for drilling holes in hard-to-access areas
Construction sites- for drilling holes for the installation of posts, poles and other construction elements
Tapered drill rods come in different taper angles ranging from 7°, 11°, and 12°. The right taper angle depends on the rock drilling operation and surface hardness.
The Minetech tapered rod is treated with carburize, which enhances the durability and toughness of the material. The carburize treatment improves the surface hardness of the rod, making it resistant to wear and damage caused by drilling activities. This workmanship ensures that the Minetech tapered rod can withstand the harsh conditions of rock drilling and perform efficiently over a long period.
Our tapered drill rods are designed to withstand the tough conditions encountered during rock drilling. The rods play a critical role in transferring the percussion energy from the rock drill to the drilling bit and ultimately into the rock. As such, they are subjected to high bending stress and are prone to damage caused by the corrosive water used to flush the holes during drilling.
Despite these challenging conditions, our tapered drill rods are built to last. Constructed from high-quality materials and designed with precision, our rods deliver exceptional performance and reliability. Whether drilling deep into the earth or working in challenging surface conditions, our tapered drill rods are up to the task.
