The disc features silicon carbide mineral bonded to a 3 mil polyester film backing, delivering a stable, consistent cutting surface. At 5 inches in diameter, it is sized for standard lapping fixtures and polishing machines. The tight particle distribution across the abrasive layer ensures repeatable cut rates, predictable surface finish, and extended disc life — all critical performance factors in high-tolerance polishing environments.\u003c\/p\u003e\n\u003cp\u003eThis disc is suited for fiber optic connector end-face polishing and metallurgical sample preparation where surface finish uniformity is essential. It is available in multiple micron grades — 5.0, 9.0, 15.0, and 30.0 micron — allowing users to select the appropriate grit for rough stock removal through final finish polishing. The polyester film backing resists tearing and maintains dimensional stability under wet or dry polishing conditions. Technicians working in fiber optic splicing labs, cable assembly operations, and materials testing facilities are the primary users of this product.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSilicon carbide mineral on 3 mil polyester film backing for dimensional stability\u003c\/li\u003e\n  \u003cli\u003eTight particle distribution for consistent cut rate and predictable surface finish\u003c\/li\u003e\n  \u003cli\u003eAvailable in 5.0, 9.0, 15.0, and 30.0 micron grades\u003c\/li\u003e\n  \u003cli\u003e5 inch diameter fits standard lapping fixtures and polishing machines\u003c\/li\u003e\n  \u003cli\u003eAvailable in disc, sheet, and roll formats\u003c\/li\u003e\n  \u003cli\u003eSuited for both fiber optic end-face polishing and metallurgical sample prep\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in fiber optic polishing and metallurgical lapping applications requiring silicon carbide abrasive media on standard 5 inch lapping fixtures and polishing equipment.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eMounting and use of lapping discs should follow the equipment manufacturer guidelines for the specific polishing fixture or machine in use. Ensure the fixture platen is clean and free of debris before applying the disc to prevent uneven seating. When polishing fiber optic connectors, follow industry cleanliness standards to avoid contamination of end-face surfaces. Spent discs should be discarded rather than reused past their effective life to maintain finish consistency.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Mineral\u003c\/strong\u003e: Silicon Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: 3 mil Polyester Film\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAvailable Micron Grades\u003c\/strong\u003e: 5.0, 9.0, 15.0, 30.0 micron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 4.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 13.9 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 10.98 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 4.8 inches\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: 500\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 051141417974\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: 7000044797\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51343327330610,"sku":"7000044797","price":402.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310535576.jpg?v=1782020168","url":"https:\/\/voomisupply.com\/products\/3m-7000044797-silicon-carbide-lapping-disc-5-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
