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

Large-diameter wet cutting jobs in structural concrete demand the reliability this Diamond Products core bit delivers. The black-coated diamond segments handle continuous wet operation through reinforced concrete, cutting clean holes for HVAC penetrations, plumbing stacks, and electrical conduit runs in commercial and industrial settings. Wet cutting keeps the bit cool during extended use while controlling dust on active job sites. The large diameter design tackles major openings in foundation walls, floor slabs, and load-bearing structures where smaller bits can't reach. Engineered for professionals running high-torque core rigs on demanding commercial projects, this bit handles the heavy work that general-purpose tooling won't survive. Built for concrete cutting contractors and mechanical trades running large-diameter penetrations in structural applications.
