CMT Diamond Dry Hole Saw - 5/8 in. (16mm) with Hexagonal Shank is a precision dry-cutting hole saw engineered for drilling through hard materials like ceramic tile, granite, marble, and artificial stone. Equipped with a diamond grit cutting edge, this compact 5/8 in. hole saw delivers fast, clean-edged holes in demanding surfaces without the need for water cooling - making it a practical choice for renovation, countertop fabrication, and tile installation work. The hexagonal shank ensures a secure grip in standard drill chucks, reducing slippage during high-torque drilling operations.

Key Features

• Diamond Grit Cutting Edge with Cubo-Octahedral Crystals - inclusion-free, heat-resistant diamond crystals cut through ceramic, granite, marble, and artificial stone faster and with longer service life compared to conventional abrasive hole saws, reducing replacement frequency on demanding job sites.
• Dry Cutting Design - formulated to cut hard tile and stone without continuous water cooling, simplifying the drilling process on finished surfaces, countertops, and installed tilework where water management is impractical.
• Hexagonal Shank - the hex shank seats firmly in both corded and cordless drill chucks, preventing bit rotation and slippage even under the higher torque loads required when drilling through dense stone and hard ceramic.
• 5/8 in. (16mm) Cutting Diameter - a compact bore size ideally suited for routing cables, pipes, and fixtures through tile, gres, granite, marble, and Silestone panels where precision hole sizing is critical.
• 1 3/8 in. Cutting Height - sufficient cutting depth to pass through standard tile thicknesses and stone slabs in a single controlled pass, minimizing repositioning and reducing the risk of edge chipping.
• Operating Range of 2,200 - 4,000 RPM - a defined speed window helps the operator select the correct drill setting, protecting the diamond coating from overheating and ensuring consistent cut quality across materials.
• 3 1/8 in. Overall Length - the compact total length keeps the bit maneuverable in tight spaces and works efficiently with both full-size corded drills and cordless drill drivers with adequate voltage.

Why This Product

• Designed specifically for hard natural stone and engineered stone surfaces - ceramic, gres, granite, marble, and artificial stones like Okite, Silestone, and Formica - so installers and fabricators get a tool matched precisely to the materials they work with daily.
• The dry cutting capability eliminates water containment setup on finished installations, making it practical for field repairs, bathroom and kitchen tile work, and countertop drilling where wet tools create cleanup and surface-protection challenges.
• The cubo-octahedral diamond crystal structure means the cutting edge stays sharper longer and resists heat buildup during friction-intensive stone drilling, giving tradespeople more cuts per bit and lower cost per hole.
• At just 5/8 in. in diameter with a hex shank, this hole saw pairs with standard cordless drills (minimum 14V recommended) - no specialty arbor or dedicated wet-cutting equipment required, lowering the barrier to getting precision results on hard tile and stone.
