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

Large-diameter openings for HVAC, plumbing, and electrical chases require a core bit that can handle wet cutting through reinforced concrete. This Diamond Products black series bit delivers consistent performance on large-bore applications where standard bits fail. The wet cutting design manages heat buildup during extended drilling sessions, while the diamond segment construction handles rebar and aggregate without segment loss. The large diameter configuration cuts clean holes in one pass, eliminating the need for multiple smaller penetrations or chipping out rough openings. Built for mechanical contractors, plumbers, and electricians running commercial building infrastructure through structural concrete.
