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

Large-diameter core drilling through structural concrete for HVAC, plumbing, and electrical chases requires a bit that can handle continuous wet cutting without degradation. This Diamond Products core bit features a black-coated barrel designed for large-bore applications in reinforced concrete, block, and masonry. Wet cutting keeps the diamond segments cool during extended drilling operations while clearing slurry from the cut. The large diameter configuration handles the demanding penetrations needed in commercial and industrial construction where standard bits won't reach. Engineered for professional concrete cutting contractors and mechanical trades running high-horsepower core rigs on job sites requiring clean, accurate large-diameter holes.
