MIRCALE Fully carburized taper drill rod
Fully-carburized Taper Drill Rod is to increase the surface carbon content of the drill rod through the carburization craft, level up the surface hardness and the overall strength, and increase the service life of the taper drill rod. Compared with the conventional taper drill rod, Fully-carburized Taper Drill Rod is high in strength and good in abrasive resistance. Under the same industrial and mining, the life of fully-carburized taper drill rods is times of that of the common taper drill rods.
