Description:
The plug hole integral rock rod is widely used in stone pit field to drill small holes (13mm -23mm) for Y6, Y10 handheld pneumatic rock drills or G10 G15 pneumatic splitter, and hand splitter aslo . Because of the integration of the rods and bits, the rock rod can be matched directly with rock drills without shank adapter or coupling sleeve, these advantages avoid the wastage of energy, and improve the drilling efficiency remarkably.
