The Ultimate Solution for Hard Materials

When outfitting a modern kitchen or bathroom, tradespeople are increasingly faced with ultra-hard materials like porcelain tiles, granite effect ceramics, and thick glass. Standard toothed hole saws will instantly blunt, burn out, or catastrophically crack these brittle surfaces. Our High Performance Diamond Grit Hole Saws bypass this problem entirely. Instead of relying on sharp metal teeth to rip through material, these saws utilize a grinding action. A premium layer of synthetic diamond grit effortlessly abrades the toughest non-metallics, resulting in a rapid cut with an exceptionally smooth surface finish. This ensures your expensive tiles and glass panels remain pristine, with clean, factory-like edges.

Engineered for High-Speed Precision

The construction of these hole saws is tailored for extreme durability and high-speed performance. The cutting edge consists of industrial-grade synthetic diamond grit that is permanently bonded to a tough, heavy-duty steel body. This advanced bonding process prevents the grit from stripping away under heavy friction, ensuring a long operational life. The geometry of the steel body and the grit coating provides the perfect amount of clearance, allowing the saw to spin at high speeds without binding in the hole. With a generous cutting depth of 38mm (1.1/2″), these tools are more than capable of handling thick natural stone, double-layered brick, and heavy-duty masonry in a single pass.

Essential Practices for Perfect Cuts

To get the most out of your Diamond Grit Hole Saw, proper drilling technique is vital. Because the diamond grit relies on friction to abrade the material, it generates a significant amount of heat. It is an absolute requirement that coolant typically a continuous flow of water—is used at all times while drilling. This not only preserves the diamond edge and flushes away the abrasive slurry, but it also prevents thermal shock from cracking your tiles or glass. Paired with a suitable arbor and a carbide-tipped pilot drill, these saws offer unparalleled accuracy. Please note: While exceptional on non-hardened glass, these saws must never be used on tempered or hardened glass, which is designed to shatter upon penetration.

Frequently Asked Questions

Do I really need to use water or coolant with this hole saw?

Yes, it is absolutely essential. Drilling hard materials with diamond grit creates extreme heat. A continuous flow of coolant or water prevents the diamond grit from burning off, flushes out the abrasive dust, and prevents your tile or glass from cracking due to heat expansion.

Can I use this hole saw on toughened or tempered glass?

No. You should never attempt to drill into hardened or tempered glass. The structural tension inside tempered glass means it will instantly shatter into thousands of pieces the moment the surface is penetrated, regardless of the tool used. These saws are strictly for non-hardened glass.

Can I use this to drill through a steel plate behind a tile?

No, these diamond grit hole saws are specifically engineered as a cutting solution for non-metallics only. If you hit metal (like a steel backing plate or a thick pipe), it will strip the diamond grit and ruin the saw. You would need to switch to a bi-metal hole saw for the metal layer
