CMT Diamond Dry Hole Saw - 1 3/8" Diameter is a premium dry-cutting hole saw engineered for precise, clean-diameter holes in hard tiles, natural stones, and engineered stone surfaces. Filled with cooling wax to manage heat during dry operation, this hole saw pairs with an angle grinder via a 5/8"-11UNC spindle connection, delivering consistent results in demanding tile and stonework applications without the need for water cooling.

Key Features

• Diamond Dry Hole Saw Design - built specifically for dry cutting through hard tiles, stones, and artificial stones, eliminating the need for a continuous water supply on the job site and keeping the work area cleaner during installation.
• Cooling Wax Fill - the integrated cooling wax melts during operation to dissipate heat at the cutting edge, protecting the diamond grit and the workpiece material and extending the usable life of the saw.
• 5/8"-11UNC Shank - the standard 5/8"-11UNC threaded connection mounts directly to common angle grinders, making this a practical, versatile tool for contractors and tile setters who already own compatible equipment.
• 1 3/8" Cutting Diameter - produces a precise 1 3/8" hole suited for plumbing and fixture pass-throughs in tile and stone, where dimensional accuracy matters.
• 40mm Cutting Depth with 2 3/8" Total Length - the 40mm cutting depth accommodates typical tile and stone thicknesses, while the compact 2 3/8" overall length keeps the tool manageable on an angle grinder.
• Right-Hand Rotation - matches the standard rotation direction of angle grinders for safe, compatible operation without modification.
• Up to 14,000 RPM Rated - engineered to handle the high rotational speeds of angle grinders, supporting efficient material removal while maintaining structural integrity of the saw body.

Why This Product

• Dry cutting capability combined with an internal cooling wax fill means you can drill through hard granite, marble, ceramic, gres, or engineered stone surfaces like Okite and Silestone without setting up water supply lines - a real advantage in finished spaces or job sites where water management is difficult.
• The 5/8"-11UNC threaded shank connects to standard angle grinders already common on tile and stone job sites, so no specialty adapter or dedicated drilling machine is required to put this saw to work.
• A 1 3/8" diameter hole is a practical size for many fixture and pipe pass-through applications in hard tile and stone, and the 40mm cutting depth means you can work through typical material thicknesses in a single pass.
• CMT's diamond construction is matched to hard, abrasive materials - ceramic, gres, granite, marble, and artificial stones - where standard bi-metal or carbide hole saws would wear prematurely or produce ragged edges, making this a purpose-built solution for the right class of materials.
