Hole openers allow the drilling of large bores even with a relatively low rig capacity, thus reducing drilling costs. By enlarging a pilot bore, they lower the torque on the drill string and assist in drilling a straighter hole. Manufactured from a single piece of full-length heat treated AISI 4145H steel, our hole opener withstands extreme force during drilling.
