Dry Core Bit - Premium Black Dry Hole Saw

Designed for electricians and plumbers drilling clean penetrations through cured concrete walls and floors without water mess. This dry core bit uses vacuum-brazed diamond segments that cut through concrete, block, and masonry while generating minimal dust when paired with proper extraction. The black-coated barrel dissipates heat during extended cuts, letting you work continuously on job sites where wet cutting isn't practical. Standard arbor fits most rotary hammers and core drill rigs you already own. Thread configuration allows quick bit changes between different diameter holes throughout the day. Diamond Products engineers this bit for professionals running multiple penetrations on commercial and residential projects where clean, dry drilling is required.
