The CMT 552-738 Diamond Dry Hole Saw is a professional-grade cutting tool engineered for drilling precise, clean holes through hard tiles, natural stone, and engineered stone surfaces. With a 1 1/2 in. cutting diameter, a 1 9/16 in. cutting height, and a 5/8 in. - 11UNC shank designed for angle grinder use, this dry-cutting hole saw delivers reliable performance on demanding materials like ceramic, granite, marble, and artificial stone. The diamond-coated cutting edge and integrated cooling wax make it a practical choice for tile setters, stone fabricators, and contractors who need consistent results without the mess of wet cutting setups.

Key Features

• Diamond Grit Cutting Edge - provides fast, aggressive material removal through hard tiles, granite, marble, and artificial stone, reducing cutting time on tough substrates
• Filled with Cooling Wax - the integrated wax melts during operation to cool the blade and workpiece, extending tool life and protecting the stone surface from heat-related damage during dry cutting
• Dry Cutting Design - eliminates the need for water supply or wet-cutting equipment, making this hole saw ideal for on-site tile and stone drilling where water management is inconvenient
• 5/8 in. - 11UNC Shank - compatible with standard angle grinder threads, giving tradespeople a straightforward mount without adapters or specialty tooling
• Right-Hand Rotation at up to 14,000 RPM - matched to the direction and speed of common angle grinders for controlled, smooth hole cutting
• 1 1/2 in. Cutting Diameter - a practical size for fixture holes, plumbing penetrations, and hardware cutouts in tile and stone installations
• 1 9/16 in. Cutting Height with 40mm Cutting Depth - sufficient depth for most tile and stone thicknesses encountered in residential and commercial applications
• Material Code DP (Diamond) - purpose-built for hard, abrasive materials that would quickly dull conventional carbide or steel hole saws

Why This Product

• If you are drilling through granite countertops, porcelain floor tiles, or engineered stone like Silestone or Okite, conventional hole saws wear out quickly - this diamond dry hole saw is specifically rated for those hard, abrasive materials
• The built-in cooling wax eliminates the need for a separate water supply or wet-cutting rig, making it a practical choice for installers working on finished job sites where water control is a concern
• The 5/8 in. - 11UNC thread mounts directly to standard angle grinders, so there is no need to purchase additional adapters or specialty equipment to put this tool to work
• A 14,000 RPM maximum rating means this hole saw can keep pace with high-speed angle grinder operation, reducing cut time on dense stone without overloading the tool
