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

Designed for plumbing and electrical contractors drilling large-diameter penetrations through foundation walls and structural concrete. This wet cut diamond core bit handles the demanding work of creating openings for major utility lines, HVAC chases, and pipe runs where precision matters. The black-coated diamond segments deliver consistent cutting performance in reinforced concrete applications. Wet cutting keeps the bit cool during extended drilling operations and controls dust on active job sites. The large diameter configuration tackles substantial bore requirements that smaller bits can't handle. Professional-grade construction stands up to daily use on commercial and industrial projects. Built for contractors and facility maintenance crews running heavy-duty core drilling equipment who need reliable performance on thick concrete pours.
