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

Designed for HVAC and plumbing contractors cutting large-diameter penetrations through structural concrete walls and floors. This wet-cut diamond core bit handles the heavy-duty boring work required for commercial and industrial installations where precision matters. The large diameter configuration allows you to drill openings for major pipe runs, electrical conduit bundles, and mechanical system pass-throughs in a single operation. Wet cutting keeps the diamond segments cool during extended drilling sessions while controlling dust on active job sites. The black-coated barrel provides corrosion resistance when working in damp conditions or near grade. Built for mechanical contractors and concrete cutting specialists running high-horsepower core rigs on commercial projects.
