It uses 3M Precision Shaped Grain abrasive technology to deliver higher cut rates and longer service life compared to conventional fibre discs. At 3 inches in diameter with a 36-grit designation and a maximum operating speed of 12000 RPM, this disc is built for demanding metalworking tasks including weld removal, beveling, edge chamfering, blending, and finish refinement. The Roloca attachment system locks the disc securely onto the backing plate without tools. Metal fabricators and industrial maintenance trades rely on this disc for heavy-duty grinding applications where speed and disc longevity are critical.\u003c\/p\u003e\n\u003cp\u003eThis disc is suited for use in metal fabrication shops, structural steel work, and industrial maintenance environments where carbon steel grinding, weld blending, and surface preparation are routine operations. The 3-inch format fits compact angle grinders and die grinders configured with a compatible Roloca backing plate. The 36-grit cut level makes it appropriate for aggressive stock removal rather than fine finishing passes. It is sold individually and is a fit for professionals who cycle through abrasives at high volume and need consistent, repeatable cut performance across a full workday.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3M Precision Shaped Grain delivers higher cut rates and longer disc life than conventional abrasive minerals\u003c\/li\u003e\n  \u003cli\u003eOptimized for heavy-duty carbon steel applications including weld grinding, beveling, and edge chamfering\u003c\/li\u003e\n  \u003cli\u003eStiff fibre backing and strong resin bond provide tear-resistance and structural durability under load\u003c\/li\u003e\n  \u003cli\u003eRoloca attachment system locks disc to backing plate securely with no tools required\u003c\/li\u003e\n  \u003cli\u003e12000 RPM maximum operating speed suits compact angle grinders and die grinders\u003c\/li\u003e\n  \u003cli\u003e36-grit designation targets aggressive stock removal and rapid weld blending\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with compatible Roloca backing plates on angle grinders and die grinders rated for a 3-inch disc at up to 12000 RPM.

Verify that the grinder spindle speed does not exceed the 12000 RPM maximum rating marked on the disc before operation. The Roloca attachment system is tool-free, but inspect the backing plate for wear or damage before mounting a new disc. Always use appropriate PPE including eye protection and gloves when operating abrasive grinding equipment, in accordance with applicable ANSI and OSHA standards for abrasive wheel machinery.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 36\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Operating Speed\u003c\/strong\u003e: 12000 RPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Type\u003c\/strong\u003e: 3M Precision Shaped Grain\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Type\u003c\/strong\u003e: Stiff Fibre\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAttachment System\u003c\/strong\u003e: Roloca (tool-free)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Carbon Steel Grinding, Weld Removal, Blending, Beveling\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 5.272 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\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: 7100100942\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51347313164594,"sku":"7100100942","price":694.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310536065.jpg?v=1782101212","url":"https:\/\/voomisupply.com\/products\/3m-7100100942-roloca-782c-fibre-disc-36-grit-3-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
