The disc uses a blended mineral system that combines ceramic grain with aluminum oxide to maintain a consistent cut rate across the life of the disc. At 6 inches in diameter and 120 grit, it targets the intermediate sanding stages where surface leveling and scratch refinement matter most. An anti-loading coating keeps the cutting surface clear of dust and debris, extending disc life between changes. Licensed body technicians and automotive painters are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis disc is built for use in collision repair and refinishing environments, covering the full paint prep sequence from featheredging and block sanding to final surface prep before primer application. The multi-hole pattern is engineered to align with most backup pads and supports dust extraction systems common in professional shop environments. The Hookit attachment system allows fast disc changes without tools, reducing downtime during production work. Both passenger vehicle and light truck body repair applications are typical use cases.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCeramic and aluminum oxide mineral blend for sustained cut rate and abrasive performance\u003c\/li\u003e\n  \u003cli\u003eAnti-loading coating resists clogging from paint dust and body filler debris\u003c\/li\u003e\n  \u003cli\u003eMulti-hole pattern aligns with most backup pads and supports dust extraction\u003c\/li\u003e\n  \u003cli\u003eHookit hook-and-loop attachment for fast, tool-free disc changes\u003c\/li\u003e\n  \u003cli\u003eUpgraded resin bond improves disc durability and finish consistency\u003c\/li\u003e\n  \u003cli\u003e6 inch diameter at 120 grit suits intermediate paint prep and scratch refinement stages\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Hookit-compatible backup pads; the multi-hole pattern aligns with most standard 6 inch hook-and-loop backup pads used in automotive refinishing applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by automotive body technicians using a dual-action or rotary sander fitted with a compatible Hookit backup pad. Confirm the backup pad hole pattern aligns with the disc before use to maintain dust extraction performance. Do not exceed the tool's rated RPM for 6 inch discs. Inspect the disc surface before each use and discard any disc showing tears, delamination, or excessive loading.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 120\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Mineral\u003c\/strong\u003e: Ceramic and Aluminum Oxide blend\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\u003eDisc Pattern\u003c\/strong\u003e: Multi-hole\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 5.14 pounds\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\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: 7100199409\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51345766777138,"sku":"7100199409","price":224.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310531615.jpg?v=1782062403","url":"https:\/\/voomisupply.com\/products\/3m-7100199409-hookit-321u-abrasive-disc-6-inch-120-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
