Drill King International, L.P. manufactures hole-openers of all sizes and designs. We manufacture our hole-openers with highest grade of aircraft quality steel available. We manufacture from 6″-36″ diameters with any size pilot hole required.
We specialize in customization of hole openers where you may add an air hole through the pilot and/or carbide buttons on the pilot for better evacuation and cleaning of the hole thus reducing wear on the steel diameter. At any given time, we have several standard hole opener shanks in stock and in process, so please keep us in mind for all your hole opener needs.
