Product Description
The CMT 552-712 Diamond Dry Hole Saw from CMT is a 1/2" diameter dry-cutting hole saw engineered for drilling through hard tiles, natural stones, and artificial stones using an angle grinder. Fitted with a 5/8"-11UNC threaded shank and filled with integrated cooling wax, this diamond hole saw delivers precise, clean bores through demanding materials like ceramic, granite, and engineered stone surfaces - without requiring water or a wet setup.
Key Features
- Diamond dry hole saw design - allows dry cutting through hard tiles, stones, and artificial stones without needing a continuous water supply, making it faster and cleaner to use on job sites.
- Filled with cooling wax - the wax melts during drilling to regulate heat at the cutting edge, protecting both the blade and the workpiece and extending the working life of the hole saw.
- 5/8"-11UNC threaded shank - provides a secure, direct mount to a compatible angle grinder, eliminating the need for adapter hardware and ensuring stable, vibration-reduced operation.
- Right-hand (RH) rotation - matched to standard angle grinder spindle direction so the tool threads on securely and the cutting edge engages material correctly during operation.
- Up to 14,000 RPM rated - supports high-speed operation on angle grinders, enabling efficient material removal through dense stone and tile without bogging down.
- 1 3/8" cutting height with 35mm cutting depth - provides enough depth capacity for most standard tile and stone thicknesses in countertop, flooring, and wall tile installations.
- Compact 1/2" cutting diameter - ideal for precision holes in tile and stone, such as faucet holes, drain cutouts, and fixture penetrations where a small-diameter bore is required.
Why This Product
- Designed specifically for hard, dense materials - ceramic tile, gres, granite, marble, and artificial stones - this hole saw handles applications where standard bi-metal or carbide hole saws fail or wear out prematurely.
- The built-in cooling wax eliminates the need for a separate water supply or wet drilling setup, making dry cuts practical in finished spaces where water damage is a concern.
- The 5/8"-11UNC shank threads directly onto most standard angle grinder spindles, so there is no need to source a separate adapter to get started.
- At only 1/2" in diameter, this is one of the smallest diamond hole saws available for angle grinders, giving installers a precise option for tight fixture holes and pilot-bore work in stone and tile.

Frequently Asked Questions
What type of angle grinder spindle does this hole saw fit?
The CMT 552-712 has a 5/8"-11UNC threaded shank, which is the standard spindle thread found on most 4" to 5" angle grinders. It threads directly onto the grinder spindle with no adapter required.
Can this hole saw be used with water for wet cutting?
This hole saw is specifically designed for dry cutting. It is filled with cooling wax that melts during drilling to manage heat at the cutting edge, so a water supply is not needed or recommended for normal operation.
What is the maximum safe operating speed for this hole saw?
The CMT 552-712 is rated for a maximum of 14,000 RPM. Always verify that your angle grinder's no-load speed does not exceed this rating before use.
Is this hole saw suitable for cutting soft materials like wood or drywall?
No - this diamond hole saw is designed specifically for hard tiles (ceramic and gres), hard natural stones (such as granite and marble), and artificial stones. It is not intended for soft materials like wood, drywall, or plastic.
