Concrete Core Drill Bit - Premium Black Wet Segmented Core Bits

Designed for HVAC contractors drilling vent holes through poured concrete walls and foundation slabs, this wet segmented core bit delivers consistent performance on residential and light commercial jobs. The black segmented design provides efficient cooling and debris removal during wet drilling operations, extending bit life and maintaining cutting speed through reinforced concrete. Diamond Products engineers this bit for use with handheld core drilling rigs and angle grinders equipped with the proper arbor. The wet segmentation pattern reduces heat buildup while the diamond-bonded segments cut clean holes without wandering or binding. Compatible with standard water delivery systems to keep the cutting surface cool and flush out concrete slurry. Built for plumbers, electricians, and mechanical contractors who need reliable core drilling tools for penetration work.
