Built on a strong polyester film backing, the disc uses micron-graded diamond mineral to deliver close-tolerance finishes with consistent, repeatable results. It is suited for medium stock removal applications where tight surface-finish requirements must be met. Machinists, tool and die makers, and precision grinding technicians are the primary users of this abrasive product.\u003c\/p\u003e\n\u003cp\u003eThe 675L disc is used on hard metals, thermal spray coatings, ceramics, carbides, chilled iron, and granite. It performs in both wet and dry operating conditions, giving operators flexibility depending on the workpiece material and machining setup. The disc is color-coded by grade, which reduces the risk of selecting the wrong abrasive during multi-step finishing operations. It is available in a range of micron grades to support progressive material removal sequences.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicron-graded diamond mineral for close-tolerance precision finishes\u003c\/li\u003e\n  \u003cli\u003ePolyester film backing provides dimensional stability during use\u003c\/li\u003e\n  \u003cli\u003eSuitable for medium stock removal on hard and abrasion-resistant materials\u003c\/li\u003e\n  \u003cli\u003eRuns wet or dry for application flexibility\u003c\/li\u003e\n  \u003cli\u003eColor-coded by grade to reduce operator error in multi-step processes\u003c\/li\u003e\n  \u003cli\u003e3-inch diameter disc format for use with compatible backing plates and holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on hard metals, thermal spray coatings, ceramics, carbides, chilled iron, and granite surfaces requiring precision microfinishing.

Ensure the backing plate surface is clean and free of debris before mounting the disc to maintain flat, even contact with the workpiece. When running wet, verify that the coolant or lubricant used is compatible with the workpiece material and disc construction. Inspect the disc before each use and replace if mineral loading, glazing, or backing damage is observed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Mineral\u003c\/strong\u003e: Diamond\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: Polyester film\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrading System\u003c\/strong\u003e: Micron-graded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOperating Conditions\u003c\/strong\u003e: Wet or dry\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 5.349 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 8.8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 6.7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 6.9 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 638060061645\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: 7100189485\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51346821939506,"sku":"7100189485","price":4675.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310519208.jpg?v=1782091436","url":"https:\/\/voomisupply.com\/products\/3m-7100189485-microfinishing-film-disc-675l-3-inch-diamond","provider":"Voomi Supply","version":"1.0","type":"link"}
