Dry Core Bits - Star Blue Dry Hole Saw

Designed for electricians and plumbers drilling clean holes through cured concrete for conduit and pipe runs, the Star Blue Dry Hole Saw delivers fast cutting without water hookup requirements. This dry core bit uses vacuum-brazed diamond segments that maintain cutting speed in reinforced concrete, block, and brick. The dry operation means no slurry mess on finished floors and no need for water supply lines in occupied buildings or upper-story installations. Diamond Products engineers this bit for angle grinder mounting, giving you the portability to move between penetrations quickly. The Star Blue segment bond handles the heat generated during dry drilling while maintaining edge integrity through multiple holes. Built for mechanical contractors and facility maintenance crews running daily installations where water-cooled drilling isn't practical.
