Diamond Core Drill Bit - Star Blue Segmented Wet Core Bits

Plumbers and electricians drilling clean penetrations through concrete slabs and walls rely on wet core bits like these for accurate, chip-free holes. The Star Blue segmented design provides efficient cutting action when paired with a core drill rig and continuous water flow. Segmented diamond cutting edges handle reinforced concrete, block, and masonry materials while maintaining consistent diameter throughout the cut. Wet drilling keeps the bit cool and extends diamond life compared to dry cutting methods. The segments allow slurry to evacuate from the hole during operation, preventing bit binding and maintaining cutting speed. These core bits deliver the clean, precise holes needed for conduit runs, pipe chases, and HVAC installations. Built for mechanical contractors, plumbers, and electricians who need reliable performance on commercial and residential concrete drilling applications.
