Built on a hook-and-loop QRS backing, the disc uses a metal-plated bond to securely anchor micron-graded diamond abrasive particles, delivering consistent cut rates alongside an improved surface finish. At 5 inches in diameter and 1 inch in width, the M300 grit designation makes it well suited for controlled material removal where precision and durability are both required. Fabricators, tool-and-die technicians, and specialty tradespeople working with demanding substrates rely on this disc for its resistance to premature wear.\u003c\/p\u003e\n\u003cp\u003eThis disc is designed for use on hard-to-grind materials including stone, glass, ceramic, metal, carbide, and composites. The flexible cloth construction allows it to conform to contoured or irregular surfaces, making it practical for both flat stock and curved workpieces. The QRS hook-and-loop attachment system enables fast disc changes on compatible random orbital and disc sanders, reducing downtime during high-volume finishing operations in shop or field environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMetal-plated bond anchors micron-graded diamonds for secure, long-lasting abrasive retention\u003c\/li\u003e\n  \u003cli\u003eFlexible cloth backing conforms to contoured and irregular surfaces\u003c\/li\u003e\n  \u003cli\u003eQRS hook-and-loop attachment for tool-free, rapid disc changes\u003c\/li\u003e\n  \u003cli\u003eImproved durability for demanding, high-wear applications\u003c\/li\u003e\n  \u003cli\u003eBetter surface finish without sacrificing cut rates\u003c\/li\u003e\n  \u003cli\u003eCompatible with hard-to-grind materials: stone, glass, ceramic, metal, carbide, and composites\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with QRS hook-and-loop compatible disc sanders and random orbital tools.

Align the QRS hook-and-loop backing squarely onto a compatible backing pad and press firmly to seat. Inspect the disc for damage before each use and replace if the abrasive layer shows uneven wear or delamination. Follow applicable shop safety protocols including eye protection and dust control when grinding ceramic, glass, or composite materials.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit Grade\u003c\/strong\u003e: M300\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 Type\u003c\/strong\u003e: Flexible cloth with QRS hook-and-loop\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00051115197598\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: 7100224420\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51347750289714,"sku":"7100224420","price":350.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310528028.jpg?v=1782112803","url":"https:\/\/voomisupply.com\/products\/3m-7100224420-flexible-diamond-qrs-cloth-disc-5x1-in-m300","provider":"Voomi Supply","version":"1.0","type":"link"}
