Wet Core Drill Bits - Premium Black Wet Segmented Core Bits

Plumbers and electricians drilling clean holes through cured concrete walls and floors rely on wet core bits to reduce dust and extend bit life. These black wet segmented core bits from Diamond Products use water flow to cool the diamond segments during operation, preventing glazing and maintaining consistent cutting speed through reinforced concrete, block, and masonry. The segmented design allows slurry to evacuate from the cut while delivering the aggressive material removal needed for conduit runs, pipe penetrations, and anchor installations. Standard arbor fitting works with most rotary drill systems used on commercial and residential jobsites. Built for tradesmen running multiple holes per day who need reliable performance without constant bit changes.
