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

Large-diameter utility penetrations through commercial foundation walls and elevator shafts demand a core bit that can handle extended wet cutting operations. This Diamond Products core bit delivers consistent performance in large-bore applications where standard bits fall short. The black-coated diamond segments provide the durability needed for cutting through rebar-reinforced concrete and aggregate mixes commonly found in structural work. Wet cutting design maintains cutting temperature and extends segment life during deep drilling operations. Engineered for professional concrete cutting contractors and mechanical trades running high-horsepower core rigs on job sites requiring large openings for HVAC, plumbing, and electrical rough-ins.
