Wet Core Drill Bits - Premium Black Wet Segmented Core Bits

Professional plumbers and HVAC contractors rely on these wet core bits when drilling clean holes through concrete walls and floors for pipe and conduit runs. Diamond Products engineers these segmented core bits with black-coated segments that deliver consistent performance in cured concrete, block, and masonry. The wet drilling design requires water feed to cool the bit and flush debris from the cut, extending bit life and maintaining cutting speed on demanding jobsites. Segmented construction allows for faster cutting speeds compared to continuous rim bits while managing heat effectively during extended drilling operations. These bits thread onto standard core drill rigs for quick changes between hole sizes. Built for mechanical contractors and concrete cutting professionals who need reliable performance drilling penetrations in structural concrete.
