It uses a proprietary ceramic abrasive grain blended with aluminum oxide and molded into flexible, abrasive-filled bristles. This construction delivers more surface contact than wire brushes and maintains cutting performance throughout the full life of the disc. The disc handles a wide range of tasks in a single tool: stripping coatings, deburring edges, blending welds, finishing, polishing, and removing rust. The open-web bristle design runs cool and resists loading, keeping abrasive minerals cutting efficiently without clogging. Machinists, fabricators, and maintenance technicians install and operate this disc with standard Roloc-compatible angle grinders and die grinders.\u003c\/p\u003e\n\u003cp\u003eThe 7100138321 is suited for general metal fabrication, maintenance shops, and automotive or engine rebuilding environments. It performs on steel, aluminum, and a variety of other metals. The flexible bristles conform to contoured and complex part geometries, making it practical for areas that flat abrasive wheels cannot reach effectively. Light pressure is sufficient under normal use, and bristles remain safely in place throughout operation. Available grades include 50, P50, 80, P80, 120, and P120, covering coarse stock removal through finer finishing work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eProprietary ceramic abrasive grain blended with aluminum oxide for consistent finish quality throughout disc life\u003c\/li\u003e\n  \u003cli\u003eFlexible, molded abrasive-filled bristles conform to contours and complex part geometries\u003c\/li\u003e\n  \u003cli\u003eWire filament-free construction eliminates the hazard of embedded wire fragments in workpieces\u003c\/li\u003e\n  \u003cli\u003eRoloc Type S quick-change attachment system speeds disc swaps during multi-step finishing processes\u003c\/li\u003e\n  \u003cli\u003eOpen-web material runs cool and resists loading for sustained high-performance cutting\u003c\/li\u003e\n  \u003cli\u003eAvailable in grades 50, P50, 80, P80, 120, and P120 to cover stripping through finish polishing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Roloc-compatible angle grinders and die grinders accepting a Type S straight quick-change hub attachment.

Ensure the tool is powered off and air supply is disconnected before mounting or removing the disc. Thread the Type S hub onto the grinder spindle until secure before starting the tool. Apply only light pressure during use — excessive force is not required and may reduce disc life.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Type\u003c\/strong\u003e: Ceramic abrasive grain blended with aluminum oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Type\u003c\/strong\u003e: Bristle Disc\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAttachment System\u003c\/strong\u003e: Roloc Type S (Straight) quick-change\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAvailable Grades\u003c\/strong\u003e: 50, P50, 80, P80, 120, P120\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Substrates\u003c\/strong\u003e: Steel, aluminum, and other metals\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 1.077 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  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00051131075269\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: 7100138321\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51347334627634,"sku":"7100138321","price":817.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310531367.jpg?v=1782101894","url":"https:\/\/voomisupply.com\/products\/3m-7100138321-scotch-brite-roloc-bristle-disc-type-s","provider":"Voomi Supply","version":"1.0","type":"link"}
