Designed for HVAC installers and plumbers drilling large-diameter holes through concrete walls and floors for pipe penetrations and ductwork. The B1420 WS core bit delivers clean, accurate cuts in reinforced concrete, block, and masonry. Wet system design keeps the bit cool during extended drilling operations and controls dust on interior jobs. Diamond segments are engineered to handle the demands of professional drilling rigs, maintaining cutting speed through rebar and aggregate. The bit mounts to standard core drill machines and works with water feed systems for continuous operation. Built for mechanical contractors and concrete cutting specialists running high-volume drilling jobs where downtime costs money.
