The plug hole drilling rods are widely used in stone pit field to drill small holes.
Because of the integration of the rods and bits, it can be metched directly with rock drills without shank adapter or coupling sleeve, these advantages avoid the wastage of energy, and improve the drilling efficiency remarkably.
