Diamond Core Drill Bit for Concrete – Premium Black – Large Diameter Wet Cut

Large-diameter penetrations through structural concrete demand a bit that can handle extended wet cutting without losing bond integrity. This Diamond Products core bit features a black-coated barrel designed for wet applications, delivering consistent performance when drilling openings for HVAC chases, elevator shafts, and large utility runs. The wet-cut design maintains cooler operating temperatures and extends segment life during deep cuts in reinforced concrete. Diamond segments are laser-welded to prevent separation under load. The large diameter configuration handles jobs where standard bits won't reach, cutting clean holes without wandering or binding. Built for concrete cutting contractors, mechanical trades, and commercial construction crews running high-horsepower core rigs on job sites requiring large-format penetrations.
