Husqvarna Professional® B1420 | Core Drill Bit

Plumbers and electricians drilling through concrete walls and floors for pipe and conduit runs rely on professional-grade core bits that deliver clean holes without wandering. The Husqvarna Professional B1420 core drill bit cuts through concrete, block, and masonry with a diamond-impregnated segment design that maintains cutting speed throughout the life of the bit. The 14-inch diameter handles large penetrations for HVAC ductwork, sewer lines, and electrical chases in commercial and industrial settings. Wet drilling capability keeps the bit cool and controls dust on jobsites with strict air quality requirements. Designed to mount on standard core drilling rigs with compatible arbor connections. Built for mechanical contractors, utility installation crews, and concrete cutting professionals who need reliable performance on multi-hole projects.
