CMT Diamond Dry Hole Saw - 2" x 1-9/16" x 2-3/8" by CMT is engineered for precision dry cutting in hard tiles, natural stones, and engineered stone surfaces. Fitted with a 5/8"-11UNC shank for use with an angle grinder, this diamond-coated hole saw delivers clean, accurate bores through demanding materials like ceramic, granite, marble, and artificial stone - without requiring water or wet cutting setups. The diamond grit construction and integrated cooling wax make it a reliable choice for tile installers, stone fabricators, and contractors who need consistent results in dry cutting applications.

Key Features

• Diamond Grit Cutting Surface - the diamond-coated edge cuts through hard ceramic, granite, marble, and artificial stone efficiently, producing clean holes with minimal chipping and extended tool life compared to standard abrasive hole saws.
• Integrated Cooling Wax - cooling wax is filled directly into the saw body and melts during drilling to dissipate heat at the cutting zone, protecting both the blade and the workpiece and extending the usable life of the tool.
• Dry Cutting Design - no water or wet setup is required, making this hole saw practical for job sites where water access is limited or where wet cutting would damage surrounding finishes and materials.
• 5/8"-11UNC Shank - the standard 5/8"-11 threaded shank connects directly to a compatible angle grinder, giving users a secure, wobble-free mount for precise hole placement in tile and stone.
• Right-Hand Rotation (RH) - matches the standard rotation direction of angle grinders, ensuring proper cutting engagement and safe, predictable operation.
• 2" Cutting Diameter - sized for common plumbing, electrical, and fixture rough-in applications through tile and stone, reducing the need for multiple tool changes on the job.
• 1-9/16" Cutting Depth - sufficient depth to bore through typical tile, stone slab, and substrate thicknesses in a single pass, improving efficiency on installation projects.

Why This Product

• Designed specifically for hard and brittle materials - ceramic, gres, granite, marble, and engineered stones - where standard bi-metal or carbide hole saws would quickly dull or chip the material, making this the right tool for demanding stone and tile work.
• The built-in cooling wax eliminates the need to pause and apply external coolant during drilling, keeping the workflow moving and reducing the risk of heat cracking in delicate stone or glazed tile surfaces.
• The 5/8"-11UNC shank provides compatibility with standard angle grinders already common on tile and stone job sites, so no special adapter or dedicated drill press is needed for most applications.
• At 14,000 RPM maximum speed, this saw is rated for the high-speed output typical of angle grinders, meaning users can run it at full tool speed without exceeding safe operating limits for the blade.
