Dry Core Bits - Star Blue Dry Hole Saw

Designed for HVAC installers drilling clean holes through cured concrete and masonry for ductwork and ventilation systems, this dry core bit from Diamond Products delivers consistent performance without water cooling systems. The Star Blue dry hole saw uses industrial-grade diamond segments bonded to a steel core barrel, allowing you to work in interior environments where wet cutting isn't practical. The dry cutting design eliminates slurry cleanup and water containment issues common on occupied buildings and finished floors. Thread connection ensures secure attachment to compatible drilling equipment. Cuts through concrete, block, and brick with minimal dust when paired with proper vacuum extraction. Built for mechanical contractors and facility maintenance teams running penetrations in commercial and industrial settings.
