It can only be drilled after matching with the cone-shaped drill bit, and usually used for rock drilling, reaming and other quarries, coal mines, roadbeds, construction and other fields operation. The taper drill rod is used in conjunction with the taper drill bit, which is used in different occasions with different lengths. The conventional taper hole angle is 7°, the internationally accepted 12°, the taper hole diameter is conventionally Ф25, and Ф22 or other specifications can also be produced according to user needs. Generally, light rock drills are equipped with cone drills of 7 degrees and below; while high-power rock drills mainly use cone drills of 11 and 12 degrees.
