Precise concrete core drilling to make perfectly round holes with diamond cutting tools is the most widely recognized application of the core-drilling type. Concrete core drill bits consist of steel tube with diamond segments on the drilling end. These are mounded on rotating shafts of core drilling blades that are powered by electricity or hydraulics. Our drill bits range from a half inch in diameter to 18 inches.
Core drilling is used to take concrete samples and analysis of rocks and other strata, but more commonly to create openings for pipes, electrical wires and heating, ventilation and air-conditioning vents. Other uses include creating openings for fiber optics, telephone lines and computer lines.
