Core Drill Bit - Heavy Duty Orange Dry Hole Saw

Designed for HVAC installers cutting through cured concrete and masonry for ductwork and pipe routing, this heavy-duty dry core bit handles demanding drilling applications without water. The orange-coded Diamond Products design uses industrial-grade diamond segments bonded to a steel core, allowing you to drill clean holes in concrete, block, and brick using standard rotary drills. Dry cutting capability means no slurry mess on finished floors or in occupied spaces where water isn't practical. The segmented design promotes heat dissipation during extended cuts while maintaining cutting speed through reinforced materials. Fits standard arbor systems for quick bit changes between hole sizes. Built for mechanical contractors, electricians, and plumbers running penetrations through structural concrete and masonry walls.
