Husqvarna Professional® B1420 WS | Core Drill Bit

Designed for HVAC installers boring clean penetrations through structural concrete and reinforced masonry, this professional-grade core drill bit handles the demanding work of creating openings for mechanical systems and utility runs. The B1420 WS designation indicates this is a wet-cutting bit engineered to work with water cooling systems that extend diamond segment life and control dust on active jobsites. Diamond-tipped segments cut through aggregate and rebar without wandering, delivering straight holes that meet tolerance requirements for pipe sleeves and electrical conduits. The threaded arbor connection provides secure mounting to compatible Husqvarna core drill motors. Wet cutting keeps the bit cool during extended boring operations and flushes debris from the kerf for consistent cutting speed. Built for mechanical contractors, plumbers, and electricians who need reliable core drilling performance on commercial construction projects.
