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

Large-diameter core drilling through commercial concrete walls and floors demands equipment that handles extended wet cutting operations without performance drop-off. This Diamond Products core bit features industrial-grade diamond segments engineered for wet cutting applications, delivering consistent penetration rates in reinforced concrete up to 6,000 PSI. The black coating provides segment identification during multi-bit jobs while protecting the steel core body from premature wear. Designed for large-diameter holes required in mechanical room installations, elevator shaft penetrations, and underground utility access points. Wet cutting keeps diamond segments cool and extends service life while managing dust on active jobsites. Built for concrete cutting contractors and commercial drilling specialists running high-horsepower core rigs on structural concrete projects.
