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

Large-diameter wet cutting operations for HVAC and plumbing penetrations in commercial buildings demand reliable drilling performance through reinforced concrete. This Diamond Products core bit delivers consistent cutting action when paired with a compatible core drill rig and water supply system. The black coating provides visual identification on the jobsite while the diamond segment design handles aggregate and rebar encountered in structural concrete. Wet cutting keeps the bit cool and extends segment life during deep drilling applications. The large diameter configuration suits commercial and industrial projects requiring oversized openings for mechanical systems, electrical conduit runs, and utility rough-ins. Built for concrete cutting contractors and mechanical trades working on multi-story construction and renovation projects.
