Wet Core Drill Bits - Premium Black Wet Segmented Core Bits

Designed for plumbing contractors drilling clean holes through cured concrete slabs and foundation walls for pipe penetrations and utility runs. These wet segmented core bits from Diamond Products use water cooling to control dust and extend bit life during continuous drilling operations. The black segmented design provides consistent cutting performance in concrete, block, and masonry materials. Wet drilling reduces airborne silica dust and keeps the diamond segments cool under load. Compatible with standard core drill rigs equipped with water feed systems. Segments are laser-welded to the steel barrel for secure attachment during heavy-duty applications. Built for mechanical contractors, plumbers, and electricians running conduit and pipe through structural concrete.
