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

Professional plumbers and mechanical contractors rely on this tool when drilling large-diameter penetrations through structural concrete for HVAC chases and main water lines. This wet-cut diamond core bit handles the demanding work of boring oversized holes in reinforced concrete, aggregate, and masonry. The black-coated barrel delivers consistent cutting performance when paired with high-torque core drilling rigs, while water cooling prevents segment glazing and extends bit life on deep cuts. Diamond Products engineers this bit for heavy commercial and industrial applications where standard hole saws won't cut it. Built for drilling contractors and mechanical trades running large-diameter cores through structural concrete on multi-story construction sites.
