Molded, abrasive-filled flexible bristles replace wire brushes in applications including rust removal, weld burn cleanup, paint and adhesive stripping, oxide removal, and general surface conditioning. The proprietary ceramic abrasive grain delivers aggressive cutting action while maintaining consistent finish quality from first use through the end of the disc's service life. At 3 inches in diameter with a 50 grit rating, this disc suits both detailed work and broader surface areas on complex or contoured parts.\u003c\/p\u003e\u003cp\u003eThis disc is used in metal fabrication, welding finishing, industrial maintenance, and surface prep workflows. Its curved, flexible bristle design conforms to irregular and contoured surfaces, making it practical in applications where a rigid abrasive tool would lose contact. It is appropriate for use in shop environments by welders, machinists, maintenance technicians, and trade professionals who need consistent results on surface conditioning tasks. The disc contains no wire filaments, reducing the hazard of wire fragment ejection during operation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCeramic abrasive grain delivers aggressive cutting and consistent finish throughout the disc life\u003c\/li\u003e\n\u003cli\u003eFlexible molded bristles conform to contoured and complex part geometries\u003c\/li\u003e\n\u003cli\u003eRemoves paint, rust, adhesives, weld burns, heavy oxides, and surface contaminants\u003c\/li\u003e\n\u003cli\u003eNo wire filaments, reducing risk of wire fragment ejection compared to wire brushes\u003c\/li\u003e\n\u003cli\u003eBristle spacing optimized for high-loading removal tasks such as coating and adhesive stripping\u003c\/li\u003e\n\u003cli\u003eRequires less applied pressure than wire brushes to achieve effective material removal\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with angle grinders and rotary tools that accept 3 inch radial bristle discs with the appropriate arbor configuration.

Disconnect and de-energize the tool before mounting or removing the disc. Verify that the tool's maximum RPM rating meets or exceeds the disc's rated speed before use. Eye protection and appropriate PPE are required during operation, as with all abrasive disc applications.\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: 50\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Ceramic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Profile\u003c\/strong\u003e: Curved\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 1.25 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 6.9 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 3.6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 4.2 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\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: 7100138325\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51345339449650,"sku":"7100138325","price":509.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310531387.jpg?v=1782055206","url":"https:\/\/voomisupply.com\/products\/3m-7100138325-scotch-brite-bristle-disc-3-inch-50-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
