CMT 552-006 Diamond Dry Hole Saw for Power Drills & Drill Presses

The CMT 552-006 Diamond Dry Hole Saw (1/4") is a professional-grade dry-cutting hole saw engineered to deliver fast, precise holes in extremely hard building materials without the need for water. Featuring a continuous diamond grit cutting edge, this saw easily penetrates ceramic tile, porcelain, granite, marble, brick, concrete, and other abrasive surfaces with minimal chipping. Its hexagonal (hex) shank allows direct mounting in standard three-jaw drill chucks without the need for separate arbors, offering secure grip and excellent torque transfer during high-speed drilling. Optimized for operation at 2200–4000 RPM, it performs best with powerful corded or cordless drills (14 V+ recommended), delivering smooth, efficient cuts in demanding applications. Designed to pair with compatible CMT 552-series pilot drills and guides, it ensures accurate hole guidance and quick plug removal. The rugged diamond bond and reinforced steel body resist wear and heat buildup, ensuring long service life even under frequent use. Ideal for plumbers, tilers, masons, and remodelers, this diamond dry hole saw brings professional performance to challenging dry drilling tasks.
