Core Drill Bit - Super Premium Red Wet Core Bore Bit

Plumbers and electricians drilling clean holes through concrete walls and floors for pipe and conduit runs depend on wet core bits that cut fast without burning up. This Diamond Products Super Red series bit uses wet drilling to keep the diamond segments cool during extended cuts, extending bit life and maintaining consistent cutting speed. The wet core design requires a water source to flush debris and control dust, making it the right choice for indoor work where clean cuts matter. Laser-welded segments hold up to the lateral stress of handheld core drilling in cured concrete, block, and masonry. Fits standard core drill rigs with compatible arbor connections. Built for mechanical contractors and facility maintenance crews running core drills daily.
