It uses a metal-plated bond to anchor micron-graded diamonds to a heavy-duty polyester backing, delivering consistent cutting performance across flat surfaces, edges, and contours. At 3 inches in diameter and weighing 0.08 pounds, the disc is compact and lightweight, suited for precision work. The Roloca quick-change twist-on and twist-off attachment system allows grade changes without tools, reducing downtime between passes.\u003c\/p\u003e\n\u003cp\u003eThis disc is used in fabrication, finishing, and surface preparation applications where conventional abrasives lose effectiveness. Typical settings include stone and tile shops, glass fabrication, carbide tooling maintenance, ceramic part finishing, and composite material work. The open-dot abrasive pattern resists loading, which extends usable life when working on dense or fine-grained substrates. Trade professionals including fabricators, tool-and-die machinists, and surface finishing technicians are the primary installers and users.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicron-graded diamonds anchored with metal-plated bond for consistent, aggressive cutting\u003c\/li\u003e\n  \u003cli\u003eHeavy-duty polyester backing conforms to flat surfaces, edges, and contoured profiles\u003c\/li\u003e\n  \u003cli\u003eOpen-dot abrasive pattern resists loading on dense materials\u003c\/li\u003e\n  \u003cli\u003eRoloca quick-change twist-on and twist-off system minimizes grade-change downtime\u003c\/li\u003e\n  \u003cli\u003eSuitable for stone, glass, ceramic, metal, carbide, and composite substrates\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Roloca-compatible backing pads and angle grinders or die grinders that accept 3-inch Roloca-style discs.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified fabricator or machinist familiar with abrasive disc grinders. Before mounting, ensure the grinder is powered off and unplugged or locked out per OSHA lockout\/tagout requirements. Attach the disc by aligning it with the Roloca backing pad and twisting to lock. Inspect the disc for damage before each use and do not exceed the rated speed of the backing pad or tool.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.08 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Type\u003c\/strong\u003e: Diamond\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Metal-plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: Polyester\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAttachment System\u003c\/strong\u003e: Roloca quick-change twist-on and twist-off\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00051144852574\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: 3M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7010309470\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51342852784434,"sku":"7010309470","price":205.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310534909.jpg?v=1782008593","url":"https:\/\/voomisupply.com\/products\/3m-7010309470-flexible-diamond-disc-3-inch-grinding","provider":"Voomi Supply","version":"1.0","type":"link"}
