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

Designed for HVAC and plumbing contractors who need to bore large-diameter holes through foundation walls and floor slabs for pipe and duct installations. This wet-cut diamond core bit handles heavy-duty drilling in reinforced concrete, delivering clean penetrations without thermal damage to the cutting edge. The black-coated barrel reduces friction during deep cuts while the diamond matrix maintains sharp cutting performance through multiple pours. Water cooling is required to evacuate slurry and extend segment life during operation. Compatible with core drill rigs rated for large-diameter bits. Built for mechanical contractors and concrete cutting specialists working on commercial and industrial projects.
