The disc blends ceramic grain with aluminum oxide mineral abrasive to deliver consistent cut and finish across multiple sanding stages. At 6 inches in diameter and 600 grit, it targets fine surface prep, scuff sanding, and finish work on painted panels. An anti-loading coating keeps the cutting surface clear of dust and debris, extending usable disc life. Upgraded resin bonding improves disc durability under sustained use. Auto body technicians and refinishing professionals are the primary installers.\u003c\/p\u003e\u003cp\u003eThis disc is designed for use in automotive body repair and refinishing environments. The multi-hole pattern aligns with most backup pads to support dust extraction systems, reducing airborne particulate at the work surface. The 600 grit rating makes it well suited for final sanding before sealer or primer application, and for scuffing between coats. The Hookita hook-and-loop style attachment allows fast disc swaps without tools, reducing downtime during production refinishing work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCeramic and aluminum oxide mineral blend for balanced cut rate and finish quality\u003c\/li\u003e\n\u003cli\u003eAnti-loading coating reduces clogging and extends disc life\u003c\/li\u003e\n\u003cli\u003eMulti-hole pattern supports dust extraction and aligns with most backup pads\u003c\/li\u003e\n\u003cli\u003eHookita hook-and-loop attachment for tool-free disc changes\u003c\/li\u003e\n\u003cli\u003eUpgraded resin construction improves durability during extended use\u003c\/li\u003e\n\u003cli\u003e600 grit rating suited for fine surface prep and between-coat scuffing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Hookita-compatible backup pads; the multi-hole pattern aligns with most standard 6 inch backup pads used in automotive refinishing applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eAuto body technicians and refinishing professionals should mount the disc onto a compatible 6 inch Hookita backup pad before use. Confirm the backup pad is securely attached to the random orbital or DA sander before powering the tool. Inspect the disc for tears or uneven wear before each use and replace when cutting performance degrades. Follow shop ventilation and respiratory protection requirements when dry sanding painted surfaces.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 600\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Ceramic Aluminum Oxide blend\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAttachment Type\u003c\/strong\u003e: Hookita hook-and-loop\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Pattern\u003c\/strong\u003e: Multi-hole\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 3.669 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 13.8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 6.9 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 7.3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Box\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 051131362500\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: 7100199659\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51343004172594,"sku":"7100199659","price":226.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310531629.jpg?v=1782013463","url":"https:\/\/voomisupply.com\/products\/3m-7100199659-hookita-321u-disc-6-inch-600-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
