Built on a conformable open-web construction and loaded with extra coarse silicon carbide abrasive, the disc cuts aggressively without gouging or undercutting the base material. At 4 inches in diameter and rated to 11,000 RPM, it fits standard right-angle grinders and die grinders. The hook and loop Roloc-style attachment allows fast disc swaps during multi-step finishing work. Weighing just 0.13 pounds, it is light enough for extended overhead or detail work.\u003c\/p\u003e\n\u003cp\u003eThis disc is used in metal fabrication, welding prep, and surface restoration applications where coating removal must be fast but controlled. Common install scenarios include cleaning weld seams and discoloration, removing mill scale before painting or coating, and stripping rust from structural steel, pipe, and sheet metal. The open-web material resists loading and runs cool, making it suitable for prolonged use on hard metal surfaces where wire brushes tend to leave embedded wire fragments or cause base-material damage.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eExtra coarse silicon carbide abrasive removes paint, rust, and weld scale efficiently\u003c\/li\u003e\n  \u003cli\u003eNon-woven conformable construction removes coatings without gouging or undercutting base material\u003c\/li\u003e\n  \u003cli\u003eOpen-web material runs cool and resists loading for extended service life\u003c\/li\u003e\n  \u003cli\u003eHook and loop attachment provides fast disc change-out for multi-step finishing\u003c\/li\u003e\n  \u003cli\u003eRated to 11,000 RPM for use with standard right-angle and die grinders\u003c\/li\u003e\n  \u003cli\u003eOutperforms wire brushes by eliminating embedded wire contamination risk\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with hook and loop Roloc-compatible right-angle grinders and die grinders accepting 4-inch non-woven discs.

Always power down and disconnect the tool before mounting or removing the disc. Verify the tool spindle speed does not exceed the 11,000 RPM disc rating before operation. Wear appropriate PPE including eye protection and gloves during surface preparation work.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Speed\u003c\/strong\u003e: 11,000 RPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Silicon Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConstruction\u003c\/strong\u003e: Non-Woven Open Web\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAttachment Type\u003c\/strong\u003e: Hook and Loop\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.13 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00048011184708\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: 7100021755\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51346419253554,"sku":"7100021755","price":648.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310522151.jpg?v=1782079670","url":"https:\/\/voomisupply.com\/products\/3m-7100021755-scotch-brite-roloc-coating-removal-disc-4-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
