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

Plumbing contractors drilling large-diameter openings through foundation walls and floor slabs rely on this wet-cut diamond core bit to power through reinforced concrete without binding or overheating. The black-coated diamond segments deliver consistent cutting performance in structural concrete applications where precision matters. Wet cutting keeps the bit cool during extended drilling operations while controlling dust on active job sites. The large diameter design handles HVAC penetrations, electrical conduit runs, and sewer line installations in commercial and industrial settings. Compatible with core drilling rigs that provide the torque needed for heavy-duty concrete coring work. Built for mechanical contractors and concrete cutters running production drilling operations in structural concrete.
