Core Drill Bit - Pro Blue Professional Wet Core Bit

Designed for plumbers and electricians drilling clean holes through concrete walls and floors for pipe and conduit runs, this wet core bit delivers consistent performance on residential and commercial job sites. The Pro Blue series uses diamond-segment technology for cutting through reinforced concrete, block, and masonry materials. Water-cooled operation reduces dust and extends bit life by preventing segment glazing during extended drilling sessions. Standard arbor fitting works with most rotary core drill rigs up to 20 amps. Vacuum-brazed segments maintain cutting speed as you work through rebar and aggregate. Built for mechanical contractors, utility installers, and concrete cutting specialists who need reliable penetration drilling without constant bit changes.
