The abrasive mineral is aluminum oxide, resin bonded to a 5 mil polyester film backing. A friction grip coating on the backing provides slip resistance during operation, helping maintain consistent contact pressure across the workpiece. At 100 micron grit grade, this roll is suited for aggressive stock removal while still delivering a uniform surface finish. Machinists, automotive technicians, and precision grinding shops typically work with this product during camshaft and crankshaft reconditioning operations.\u003c\/p\u003e\n\u003cp\u003eThis roll is configured for use on lathe-style finishing equipment and similar cylindrical polishing setups. The 3 inch keyed core and ASO (Abrasive Surface Out) wind orientation are matched to powered film finishing machines that accept keyed-core rolls. The 8 inch width and 150 ft length provide extended run time before roll changeover, making it appropriate for production environments where downtime between media changes affects throughput. Typical applications include automotive engine component reconditioning, precision shaft finishing, and surface conditioning of cylindrical metal workpieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum oxide abrasive mineral resin bonded for consistent cut rate and long roll life\u003c\/li\u003e\n  \u003cli\u003e5 mil polyester film backing provides dimensional stability and tear resistance under tension\u003c\/li\u003e\n  \u003cli\u003eFriction grip backing coating reduces slippage during finishing strokes\u003c\/li\u003e\n  \u003cli\u003e100 micron grit grade balances aggressive stock removal with surface uniformity\u003c\/li\u003e\n  \u003cli\u003eASO wind with keyed 3 inch core for compatibility with powered film finishing machines\u003c\/li\u003e\n  \u003cli\u003e8 inch x 150 ft roll dimensions support extended production runs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on powered cylindrical film finishing machines that accept an 8 inch wide, keyed 3 inch core roll in ASO orientation.

Ensure the finishing machine is powered down and de-energized before changing rolls. Verify that core key alignment is correct before tensioning the roll to avoid tracking problems or premature edge wear. Proper workpiece speed, film feed rate, and contact pressure should be set per the machine manufacturer's specifications for the grit grade in use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Mineral\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit Grade\u003c\/strong\u003e: 100 Micron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking\u003c\/strong\u003e: 5 mil Polyester Film\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Coating\u003c\/strong\u003e: Friction Grip\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWind Orientation\u003c\/strong\u003e: ASO (Abrasive Surface Out)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRoll Width\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRoll Length\u003c\/strong\u003e: 150 ft\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCore Diameter\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCore Type\u003c\/strong\u003e: Keyed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 11 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00051144149711\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: 7000118163\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51347337871666,"sku":"7000118163","price":569.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310534079.jpg?v=1782102005","url":"https:\/\/voomisupply.com\/products\/3m-7000118163-microfinishing-film-roll-372l-100-micron","provider":"Voomi Supply","version":"1.0","type":"link"}
