Working with hydraulic drill rig, Threaded Drilling Tools are widely used in tunneling, mining and construction field because of high drilling efficiency, safety and environmental protection.
When it is hard to meet the requirements under the single-time drilling, it is used to drill the hole at second time, commonly applying to drill center hole of drifting.
