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

Large-diameter wet drilling through structural concrete walls and foundations requires a core bit that can handle continuous operation without segment loss. This Diamond Products black series core bit delivers consistent performance in reinforced concrete applications where precision and speed matter. Wet cutting design provides necessary cooling and dust control for extended drilling sessions on commercial and industrial job sites. Laser-welded diamond segments maintain cutting efficiency through rebar and aggregate while the large diameter configuration handles major penetrations for mechanical, electrical, and plumbing installations. Segments are engineered for balanced wear patterns that extend bit life across multiple pours. Built for concrete cutting contractors and mechanical trades running high-horsepower core rigs on demanding commercial projects.
