Product Description
The CMT 552-705 Diamond Dry Hole Saw is a compact, precision-ground cutting tool engineered for drilling through hard tiles, natural stones, and engineered stone surfaces without water cooling. With a 3/16 in. diameter and a 5/8 in. - 11UNC threaded shank, this CMT hole saw mounts directly to a compatible threaded arbor, making it a reliable choice for tile installers, stone fabricators, and contractors who need clean, accurate small-diameter holes in demanding materials like granite, marble, ceramic, and artificial stone. Filled with integrated cooling wax, this diamond hole saw maintains cutting temperatures during dry operation - extending tool life and protecting the workpiece surface.
Key Features
- Diamond dry hole saw design - purpose-built for dry cutting in hard tiles, stones, and artificial stones, eliminating the need for a water source on the job site and keeping setup simple and clean.
- Integrated cooling wax fill - cooling wax built into the saw body melts during drilling to regulate heat at the cutting edge, protecting the diamond grit and extending blade service life in hard ceramic and stone materials.
- 3/16 in. diameter cutting profile - delivers a precise, small-diameter hole suited to hardware installation, fixture mounting, and detail work in hard tile and stone where accuracy is critical.
- 1-3/8 in. cutting height (35mm cutting depth) - provides sufficient depth capacity to pass cleanly through standard tile thicknesses and thicker stone slabs in a single pass.
- 5/8 in. - 11UNC threaded shank - the standard 5/8 in. - 11 thread pattern ensures broad compatibility with threaded arbors and adapters commonly used in stone drilling applications.
- Right-hand rotation at up to 14,000 RPM - high maximum RPM rating allows the saw to operate efficiently with compatible tooling, delivering fast material removal in hard, abrasion-resistant surfaces.
- Suitable for hard tiles, stones, and artificial stones - a single tool handles a wide range of demanding substrates including granite, marble, ceramic, gres, and engineered surfaces like Silestone, expanding job-site versatility.
Why This Product
- Dry cutting capability combined with an integrated cooling wax fill means you can drill through hard tile and natural stone without water lines, wet setups, or containment - keeping work areas cleaner and reducing job-site preparation time.
- The 3/16 in. diameter addresses a specific small-hole need that larger hole saws cannot fill, making this the right tool when precision-sized openings are required in granite countertops, ceramic wall tile, or engineered stone panels.
- A 5/8 in. - 11UNC shank is one of the most widely adopted thread standards for stone drilling arbors, so this CMT hole saw integrates into existing tooling setups without requiring specialty adapters.
- The 35mm (1-3/8 in.) cutting depth gives the tool enough reach to handle standard tile thicknesses and moderately thick stone in a single plunge, reducing the need for stepped drilling in most typical installations.

Frequently Asked Questions
Does this hole saw require water cooling during use?
No. The CMT 552-705 is specifically designed as a dry hole saw. It is filled with cooling wax that melts during operation to manage heat at the cutting edge, so no external water source is needed. This makes it practical for tile and stone drilling in locations where wet cutting is not convenient.
What shank thread does the 552-705 use, and what does it fit?
This hole saw uses a 5/8 in. - 11UNC threaded shank. This is a standard thread pattern found on many threaded arbors and adapters used for stone and tile drilling. Confirm that your arbor or adapter matches the 5/8 in. - 11UNC thread specification before use.
What materials can this diamond hole saw cut?
The 552-705 is suitable for hard tiles (including ceramic and gres), hard natural stones (including granite and marble), and artificial stones. It is not designed for soft materials such as wood or drywall - the diamond cutting surface is optimized for hard, abrasion-resistant substrates.
What is the maximum RPM for the CMT 552-705?
The maximum rated speed is 14,000 RPM. Always confirm that your tooling and setup are rated to operate at or within this speed range, and follow all applicable safety guidelines for diamond hole saws when drilling hard tile and stone.
