The continuous diamond-coated rim cuts a circular channel through the material, removing a clean core plug and leaving a smooth, chip-free hole edge. Compatible with standard drill presses, angle grinders, and heavy-duty hand drills with water swivel adaptors for continuous coolant flow.\u003c\/p\u003e\u003cp\u003e\u003ca href=\"\/collections\/diamond-starrett-hole-saws\" class=\"cta-btn\"\u003e🔥 Shop Diamond Starrett Hole Saws\u003c\/a\u003e\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eLarge-diameter core drilling\u003c\/strong\u003e — For holes too large for standard drill bits\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContinuous diamond rim\u003c\/strong\u003e — Clean, chip-free hole edges on brittle materials\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCore removal design\u003c\/strong\u003e — Removes a clean plug for efficient, cool cutting\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill press \u0026amp; angle grinder compatible\u003c\/strong\u003e — Standard thread attachment for common tools\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWet use design\u003c\/strong\u003e — Use with water swivel adaptor for continuous coolant flow\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCompatible Materials\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eNatural stone — granite, marble, slate, sandstone, agate slabs\u003c\/li\u003e\n\u003cli\u003eGlass — art glass, fused glass, thick plate glass\u003c\/li\u003e\n\u003cli\u003eCeramic \u0026amp; porcelain tile — floor tile, wall tile, mosaic substrates\u003c\/li\u003e\n\u003cli\u003eHard minerals — quartz, obsidian, petrified wood\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eRelated Tools\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003ca href=\"\/collections\/water-swivel-adaptors\"\u003eWater Swivel Adaptors\u003c\/a\u003e — Continuous water feed for hole saw drilling\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"\/collections\/sintered-diamond-core-drills\"\u003eSintered Diamond Core Drills\u003c\/a\u003e — Long-life sintered core drills for professional use\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"\/collections\/diamond-drill-bits\"\u003eDiamond Drill Bits\u003c\/a\u003e — Smaller diameter drill bits for precision hole work\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"\/collections\/diamond-wire-hollow-drill-bits\"\u003eDiamond Wire Hollow Drill Bits\u003c\/a\u003e — Fine hollow bits for 0.8mm–4mm holes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eQ: What is a Diamond Starrett Hole Saw used for?\u003c\/strong\u003e\u003cbr\u003eA: Diamond Starrett hole saws are used for cutting large-diameter holes in stone, glass, tile, and hard minerals — applications where standard drill bits are too small. They cut a circular channel and remove a core plug, making them ideal for plumbing penetrations in tile, decorative stone inlays, and large pendant holes in stone slabs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQ: Should diamond hole saws be used wet or dry?\u003c\/strong\u003e\u003cbr\u003eA: Always use wet. A water swivel adaptor delivers continuous coolant through the hollow shank directly to the cutting rim, preventing overheating and extending saw life. Never run a diamond hole saw dry — heat buildup will rapidly destroy the diamond rim.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQ: What drill speed should I use with a diamond hole saw?\u003c\/strong\u003e\u003cbr\u003eA: Use low speed — 300–600 RPM for most stone and tile applications. Apply steady, moderate downward pressure without forcing. Slow, consistent cutting with continuous water cooling produces the cleanest holes and maximum saw life.\u003c\/li\u003e\n\u003c\/ul\u003e","products":[],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0575\/4542\/4942\/collections\/Diamond_Starrett_Core_Drill.png?v=1738200409","url":"https:\/\/hanslapidarytool.com\/collections\/diamond-starrett-hole-saws.oembed","provider":" Hans Lapidary Tool","version":"1.0","type":"link"}
