Description
Carburized tapered drill rod is widely used in underground mines and construction projects. Compared with the integral drill steel, there is energy loss in the cone joint of taper rod. The Carburized tapered drill rod can be equipped with a variety of bit to drill holes of different caliber. The bit can be repaired or replaced after wear, greatly reducing the construction cost.
Carburization is a process used to harden the entire Carburized tapered drill rod surface both internally and externally to strengthen and extend the life of the tapered drill rod.
Shank Hexagon: 19*108 mm, 22*108mm, 25*108 mm, 25*159 mm;6°,7°,11°,12°taper degree in most lengths, taper degree of drill steel is mostly imports for excellent drilling productivity.
Performance
Low use cost,low natural power consumption, easy installation and disassembly, long service life.
High strength chromium-molybdenum steel with high fatigue strength and excellent wear resistance
Application
Quarrying
Underground mining
Down the hole rock drilling
