It uses 3M Precision Shaped Grain, a ceramic abrasive mineral engineered for higher cut rates and cooler grinding temperatures compared to conventional fibre discs. Rated to 30000 RPM and built on a stiff fibre backing with a strong resin bond, this disc is suited for weld removal, blending, and finish refinement on stainless steel and high nickel alloys. A built-in grinding aid further reduces heat buildup during aggressive material removal. Licensed HVAC, metalworking, and fabrication professionals will find it performs well in both sustained grinding and intermittent blending passes.\u003c\/p\u003e\u003cp\u003eThis disc is used in light fabrication shops and heavy industrial environments alike, anywhere stainless steel or high nickel alloy workpieces require weld grinding, beveling, edge chamfering, or surface blending. The Roloc quick-change attachment system allows disc swaps without tools, making it practical for production settings where downtime between grit changes needs to stay minimal. It is sold individually and suited for use on angle grinders and inline grinders equipped with a compatible Roloc mandrel.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3M Precision Shaped Grain delivers higher cut rates and cooler cutting action versus conventional fibre discs\u003c\/li\u003e\n\u003cli\u003eBuilt-in grinding aid reduces heat buildup, protecting heat-sensitive alloys like stainless steel and high nickel alloys\u003c\/li\u003e\n\u003cli\u003eStiff fibre backing and strong resin bond resist tearing under heavy grinding loads\u003c\/li\u003e\n\u003cli\u003eRoloc quick-change attachment secures the disc without tools, reducing changeover time\u003c\/li\u003e\n\u003cli\u003eRated to 30000 RPM for compatibility with high-speed grinders\u003c\/li\u003e\n\u003cli\u003eSuitable for weld removal, beveling, edge chamfering, and surface blending\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Roloc-compatible angle grinders and inline grinders fitted with a standard Roloc mandrel.

Verify the grinder spindle speed does not exceed the 30000 RPM disc rating before operation. Wear appropriate PPE including a face shield, gloves, and hearing protection when operating grinding equipment. Follow applicable ANSI B11 and OSHA 1910.215 guidelines for abrasive wheel machinery.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 120\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Speed\u003c\/strong\u003e: 30000 RPM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Type\u003c\/strong\u003e: 3M Precision Shaped Grain (Ceramic)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacking\u003c\/strong\u003e: Stiff Fibre\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAttachment Type\u003c\/strong\u003e: Roloc Quick-Change\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 2.704 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 9.71 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 9.13 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 5.08 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 076308897043\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: 7100100964\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51347376013618,"sku":"7100100964","price":478.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310536088.jpg?v=1782103062","url":"https:\/\/voomisupply.com\/products\/3m-7100100964-roloc-fibre-disc-787c-2-in-120-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
