The disc uses micron-graded diamond mineral bonded in metal to deliver aggressive, consistent cutting action. An open dot mineral pattern allows swarf and debris to clear freely, reducing loading and extending disc life. The semi-flexible backing conforms to edges and contours, making it practical for profile work where a rigid disc would skip or chatter. Sold individually, this disc is sized at 5 inches in diameter with a 1-inch arbor and a quick-release attachment system.\u003c\/p\u003e\u003cp\u003eThis disc is suited for trade and industrial applications where conventional abrasives fail on hard substrates. Typical use cases include grinding and finishing operations on stone fabrication, glass work, ceramic components, tungsten carbide tooling, and fiber-reinforced composites. The quick-release attachment speeds up disc changes, which is useful in production environments or when switching between grit grades on the same job. The flexible backing responds to curved and contoured surfaces, reducing hand finishing time after machine grinding.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicron-graded diamond mineral delivers aggressive cut and consistent scratch pattern on hard-to-grind materials\u003c\/li\u003e\n\u003cli\u003eOpen dot mineral pattern allows swarf and debris to escape, reducing disc loading\u003c\/li\u003e\n\u003cli\u003eMetal bond anchors diamond mineral securely for extended working life\u003c\/li\u003e\n\u003cli\u003eSemi-flexible backing conforms to edges, contours, and curved surfaces\u003c\/li\u003e\n\u003cli\u003eQuick-release attachment system for fast disc changes\u003c\/li\u003e\n\u003cli\u003eCompatible with hard substrates including stone, glass, ceramics, carbides, and composites\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on random orbital and disc sanders or grinders equipped with a 1-inch arbor and quick-release (QRS) interface; suited for hard-to-grind materials including stone, glass, ceramics, carbides, and composites.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and disc changes should be performed by qualified shop or trade personnel with the tool powered down and unplugged or locked out before servicing the disc. Verify that the tool spindle speed does not exceed the rated speed of the disc before operation. Wear appropriate PPE including eye protection and gloves when handling diamond abrasives and grinding hard materials. Follow tool manufacturer guidelines and applicable safety standards for abrasive disc use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eArbor Size\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Mineral\u003c\/strong\u003e: Diamond (micron-graded)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Metal bond\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacking Type\u003c\/strong\u003e: Semi-flexible cloth\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAttachment Type\u003c\/strong\u003e: Quick-release (QRS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 5.3 x 5.3 x 1.3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUOM\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 7100036878\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51344904421682,"sku":"7100036878","price":766.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310534123.jpg?v=1782045027","url":"https:\/\/voomisupply.com\/products\/3m-7100036878-flexible-diamond-qrs-cloth-disc-5-in","provider":"Voomi Supply","version":"1.0","type":"link"}
