The disc uses a ceramic abrasive applied in an open-coat pattern across a C-weight paper backing. Ceramic abrasive self-sharpens during use, which maintains a consistent cut rate and keeps surface temperatures lower than conventional abrasives — an important advantage when working heat-sensitive metals or finishes. At 180 grit, this disc falls in the fine range, suited for smoothing and light stock removal.\u003c\/p\u003e\n\u003cp\u003eThis disc is used in automotive, fabrication, marine, and composite repair applications. The multi-hole pattern allows dust extraction without requiring alignment to a specific hole layout, which speeds disc changes and reduces airborne particulate. The open-coat construction covers approximately 50 percent of the surface with abrasive, which limits swarf loading and helps maintain consistent performance across longer use cycles. Suitable for sanding paint, plastic, composites, gelcoat, fiberglass, and carbon steel. C-weight paper backing is approximately 70 pounds, offering more rigidity and durability than lighter A- or B-weight backings while remaining foldable for hand-sanding applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCeramic abrasive self-sharpens to sustain cut rate and reduce surface heat buildup\u003c\/li\u003e\n  \u003cli\u003e180 grit fine grade for deburring, smoothing, and pre-finishing surface prep\u003c\/li\u003e\n  \u003cli\u003eOpen-coat construction covers roughly 50 percent of surface to resist swarf loading\u003c\/li\u003e\n  \u003cli\u003eMulti-hole pattern eliminates hole-alignment step during disc changes\u003c\/li\u003e\n  \u003cli\u003eC-weight paper backing provides rigidity for powered sanding and flexibility for hand use\u003c\/li\u003e\n  \u003cli\u003eHook-and-loop attachment for fast disc removal and repositioning\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on hook-and-loop random orbital and orbital sanders accepting 6-inch multi-hole discs.

Ensure the sander is powered off and unplugged before changing discs. Inspect the backing pad for wear or contamination before attaching a new disc, as a damaged pad can cause uneven pressure and premature disc failure. Use appropriate respiratory protection and dust extraction when sanding composites, fiberglass, or coated metals.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Ceramic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 180\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Grade\u003c\/strong\u003e: Fine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Coverage\u003c\/strong\u003e: Open coat, approximately 50 percent\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: Paper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Weight\u003c\/strong\u003e: C-weight, approximately 70 pounds paper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVacuum Hole Pattern\u003c\/strong\u003e: Multi-Hole\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAttachment Type\u003c\/strong\u003e: Hook-and-Loop\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 732U\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Purple\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eResistance Properties\u003c\/strong\u003e: Load resistant\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: USA (subject to change)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC\u003c\/strong\u003e: 31191506\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: 7100066679\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51524721738034,"sku":"7100066679","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3bd8c0abc882e613e132f8379cb8dd54.jpg?v=1785456384","url":"https:\/\/voomisupply.com\/products\/3m-7100066679-sanding-disc-180-grit-6-inches-ceramic","provider":"Voomi Supply","version":"1.0","type":"link"}
