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.\u003c\/p\u003e\n\u003ch3\u003eEngineered for High-Speed Precision\u003cbr\u003e\n\u003c\/h3\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003ch3\u003eEssential Practices for Perfect Cuts\u003cbr\u003e\n\u003c\/h3\u003e\n\u003cp\u003eTo 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.\u003c\/p\u003e","brand":"Starrett","offers":[{"title":"16mm - D0058","offer_id":55467084480888,"sku":"D0058","price":21.7,"currency_code":"GBP","in_stock":true},{"title":"25mm - D0100","offer_id":55467084513656,"sku":"D0100","price":29.98,"currency_code":"GBP","in_stock":true},{"title":"32mm - D0114","offer_id":55467084546424,"sku":"D0114","price":35.34,"currency_code":"GBP","in_stock":true},{"title":"51mm - D0200","offer_id":55467084579192,"sku":"D0200","price":54.1,"currency_code":"GBP","in_stock":true},{"title":"54mm - D0218","offer_id":55467084611960,"sku":"D0218","price":57.96,"currency_code":"GBP","in_stock":true},{"title":"67mm - D0258","offer_id":55467084644728,"sku":"D0258","price":65.22,"currency_code":"GBP","in_stock":true},{"title":"95mm - D0334","offer_id":55467084677496,"sku":"D0334","price":119.38,"currency_code":"GBP","in_stock":true},{"title":"127mm - D0500","offer_id":55467084710264,"sku":"D0500","price":152.66,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0802\/8658\/1049\/files\/StarrettDiamondHoleSaw.jpg?v=1771593246","url":"https:\/\/www.electrosw.co.uk\/products\/starrett-diamond-grit-hole-saws","provider":"Electro South West Ltd","version":"1.0","type":"link"}
