Wet Core Drill Bits - Premium Black Wet Segmented Core Bits

Professional plumbers and electricians rely on these core bits when drilling clean penetrations through concrete walls and floors for pipe and conduit runs. Diamond Products engineers these wet segmented core bits with a black-coated barrel and laser-welded diamond segments that handle continuous water-fed drilling in reinforced concrete, block, and masonry. The wet cutting design keeps the bit cool during extended drilling operations while flushing debris from the hole. These bits thread onto standard core drill rigs and deliver consistent performance across residential and commercial jobsites. The segmented design provides faster cutting speeds compared to continuous rim bits while maintaining clean, round holes without chipping. Built for mechanical contractors, concrete drillers, and utility installers who need reliable core drilling equipment for daily production work.
