Concrete Core Drill Bit - Premium Black Wet Segmented Core Bits

Designed for HVAC installers cutting clean holes through concrete walls and floors for ductwork and refrigerant lines, this wet segmented core bit delivers consistent performance on reinforced concrete. The black-bonded diamond segments handle the heat and friction of wet drilling applications while maintaining cutting speed through rebar and aggregate. Wet operation keeps dust down and extends bit life by preventing segment glazing during extended cuts. The segmented design allows for efficient slurry removal and cooling water circulation around the bit body. Standard arbor connection fits most handheld and rig-mounted core drilling systems. Built for mechanical contractors, plumbers, and electricians running penetrations through structural concrete on commercial and industrial job sites.
