Diamond Core Drill Bit - Star Blue Segmented Wet Core Bits

Plumbers and electricians drilling clean penetrations through cured concrete walls and floors rely on segmented wet core bits to power through demanding jobs without overheating. The Star Blue segmented design allows water to flow directly to the cutting surface, flushing debris and keeping the diamond matrix cool during extended drilling operations. These wet-use core bits deliver consistent performance in reinforced concrete, block, and masonry when paired with a core drill rig and continuous water supply. The segmented configuration reduces friction and speeds up cutting compared to continuous rim designs, making them efficient for HVAC installers, sprinkler fitters, and mechanical contractors running pipe and conduit through structural concrete. Built for trade professionals who need reliable core drilling performance on commercial and industrial job sites.
