The single roler bit is composed of a single cone and a lug matched by a bearing.According to different strata and construction requirements, different cutting struclures can be selected; wear resistant carbide are welded and cemented carbide inserts are inserted on the back of the lug.
Rotary drilling rig drives the shaft to rotate and exert positive pressure so that the rotary dril- ing bit can impact, roll and shear the rock. Crush the rock to form a crushing ring zone.Then break the middle pillar by the swing of the shaft and take the broken pillar out to form a hole.
