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

Designed for plumbing and electrical contractors drilling large-diameter penetrations through commercial foundation walls and floor slabs, this wet-cut diamond core bit handles the demanding work of creating openings for major utility lines and HVAC installations. The black-coated diamond segments deliver consistent cutting performance in reinforced concrete applications where standard bits fail. Wet cutting operation keeps the bit cool and extends segment life while reducing dust on active job sites. The large diameter configuration makes quick work of creating openings for pipe chases, conduit bundles, and mechanical system penetrations without the need for multiple passes or enlargement. Built for mechanical contractors and concrete cutting specialists running high-horsepower core rigs on structural concrete projects.
