Carburization is a process that aims to enhance the durability and longevity of tapered drill rods by hardening their entire surface, both internally and externally. This hardening process strengthens the drill rods, making them more resilient for drilling tasks.

The shank hexagon of these drill rods comes in various sizes, including 19108 mm, 22108 mm, 25108 mm, and 25159 mm. Additionally, most lengths offer a choice of taper degrees, such as 6°, 7°, 11°, and 12°, which are often imported to ensure optimal drilling productivity.
