CMT Diamond Dry Hole Saw - 1" x 1-9/16" x 2-3/8" is a precision-engineered dry cutting hole saw designed for drilling clean, accurate holes through hard tiles, natural stones, and engineered stone surfaces. Built for use with a 5/8"-11UNC threaded spindle, this CMT tool delivers reliable performance in demanding tile and stone cutting applications where precision and blade longevity are essential.

Key Features

• Diamond-grit cutting surface - cuts through hard ceramic tiles, gres, granite, marble, and artificial stones with speed and precision, reducing chipping and jagged edges on finished surfaces.
• Dry cutting design - eliminates the need for water supply or wet cutting setups, making this hole saw practical for job sites and installations where water management is inconvenient or impractical.
• Cooling wax fill - wax embedded in the core melts during drilling to lubricate and cool the cutting edge, extending blade service life and protecting both the tool and the workpiece from heat damage.
• 1" diameter cutting size - sized for common through-hole needs in tile and stone work, such as plumbing and fixture penetrations, providing a clean finished opening without the need for secondary cleanup.
• 1-9/16" cutting depth (40mm) - accommodates typical tile and stone slab thicknesses in a single pass, reducing repositioning and rework on standard installations.
• 5/8"-11UNC shank thread - standard thread size compatible with a wide range of angle grinders and rotary tools fitted with this common spindle standard, offering broad tool compatibility.
• Right-hand rotation (RH) - matches the standard rotation direction of compatible power tools, ensuring proper engagement and safe, stable cutting performance.
• 14,000 RPM rated speed - built to handle the high rotational speeds typical of angle grinders, ensuring the saw operates safely within the design limits of the tool and spindle combination.
• Diamond (DP) material construction - industrial diamond abrasive delivers consistent cutting performance across dense, abrasion-resistant materials where conventional hole saws wear quickly or fail.

Why This Product

• For trades workers cutting through granite, marble, or engineered stone countertops such as Silestone or Okite, the diamond dry cutting design handles dense, hard materials that would prematurely wear out standard bi-metal or carbide hole saws.
• The built-in cooling wax eliminates the need to manage a water supply during drilling, making it a practical, single-tool solution for dry stone and tile penetrations on active job sites.
• The 5/8"-11UNC shank is a widely used angle grinder thread standard, meaning this hole saw integrates directly with compatible tools already on the job site without requiring adapters or specialty equipment.
• A 40mm (1-9/16") cutting depth makes this saw suitable for full-thickness cuts in standard tile and stone installations, completing the bore in a single setup rather than requiring multiple passes or flip-cutting.
