Built on a durable film backing rather than standard paper, it delivers close-tolerance, consistent finishes in high-production environments. The aluminum oxide abrasive grain provides a fast cut rate and extended disc life. At 3 inches in diameter with a P500 grit rating and a maximum speed of 20000 rpm, this disc is suited for precision surface prep where finish quality matters. Licensed tradespeople and finishing technicians across marine, automotive, and fabrication trades use this disc for controlled material removal on sensitive surface materials.\u003c\/p\u003e\u003cp\u003eThis disc is intended for sanding and finishing applications on composites, gel coats, fiberglass, and polyurethane solid surfaces. Its open coat construction resists loading, making it effective when working with materials that can clog conventional abrasives quickly. The Hookit attachment system allows fast disc changes without adhesive, which improves efficiency during high-volume finishing runs. Typical applications include surface preparation before topcoat application, blending repairs on gel coat panels, and fine finishing passes on fabricated plastic components.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAluminum oxide abrasive grain delivers fast cut and long service life across multiple surface types\u003c\/li\u003e\n\u003cli\u003eFilm backing provides superior tear resistance and consistent finish tolerance compared to A-weight paper backings\u003c\/li\u003e\n\u003cli\u003eOpen coat construction reduces loading when sanding plastics, gel coats, and composites\u003c\/li\u003e\n\u003cli\u003eHookit attachment system enables quick disc changes and allows reuse over the disc life\u003c\/li\u003e\n\u003cli\u003eRated to 20000 rpm for use with compatible random orbital and disc sanders\u003c\/li\u003e\n\u003cli\u003eP500 grit for fine sanding and pre-finish surface preparation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 3-inch Hookit-compatible random orbital sanders and disc pads.

Verify the sander does not exceed the 20000 rpm maximum speed rating before operating. Inspect the disc for tears or loading before each use and replace as needed. Always wear appropriate eye protection and dust respiratory protection when sanding composites or fiberglass, as generated dust may be a health hazard.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: P500\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Mineral\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacking Type\u003c\/strong\u003e: Film\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoat Type\u003c\/strong\u003e: Open Coat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAttachment Type\u003c\/strong\u003e: Hookit (Hook and Loop)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Speed\u003c\/strong\u003e: 20000 rpm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.691 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 8.34 x 7.01 x 3.7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 051125871421\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: 7100093078\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51344788980018,"sku":"7100093078","price":275.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310530299.jpg?v=1782043736","url":"https:\/\/voomisupply.com\/products\/3m-7100093078-hookit-360l-film-disc-3-inch-p500-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
