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

Designed for HVAC and plumbing contractors drilling large-diameter penetrations through structural concrete and reinforced foundations, this wet-cut diamond core bit handles the demanding work of creating openings for mechanical systems and utility chases. The black-coated segments provide consistent cutting performance in medium to hard concrete when paired with an appropriate core rig and water supply. Large diameter sizing makes this the right choice for commercial and industrial projects requiring substantial openings for pipe runs, ductwork, and electrical conduits. The wet-cutting design controls dust and extends segment life during extended drilling operations. Built for mechanical contractors and concrete cutting specialists running commercial jobs.
