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

Description

Engineered for plumbing contractors drilling large-diameter holes through foundation walls and basement floors for sewer line installations, this wet-cut diamond core bit handles the toughest concrete drilling applications. The black-coated diamond segments provide consistent cutting performance in reinforced concrete up to 6,000 PSI. Wet cutting keeps the bit cool and extends diamond life while controlling dust on job sites. The large diameter design makes quick work of oversized penetrations for HVAC ductwork, electrical conduit bundles, and main water service entries. Compatible with heavy-duty core drilling rigs operating at proper RPM and feed pressure. Built for mechanical contractors and concrete cutting professionals running high-production drilling operations where hole quality and bit longevity matter.
