Built around 3M Precision Shaped Grain technology, the disc delivers higher cut rates and greater part-count per disc compared to conventional fibre discs. The stiff fibre backing and strong resin bond resist tearing under sustained load. At a rated speed of 30000 RPM and a working diameter of 3 inches, the disc is sized for angle grinders and disc sanders used in fabrication, maintenance, and repair environments. The Roloca attachment system locks the disc securely to compatible back-up pads without tools, reducing downtime during disc changes.\u003c\/p\u003e\u003cp\u003eThis disc is suited for heavy-duty grinding tasks in metal fabrication shops, structural steel work, and field maintenance settings. Typical applications include weld removal, weld blending, edge beveling, edge chamfering, and finish refinement on carbon steel workpieces. The 60-grit designation positions it firmly in the aggressive-cut range, making it appropriate where fast stock removal is the priority before transitioning to finer finishing steps. Both professional fabricators and maintenance tradespeople working on structural components will find this disc effective for high-volume material removal.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3M Precision Shaped Grain technology delivers higher cut rates than conventional abrasive minerals\u003c\/li\u003e\n\u003cli\u003e60-grit coated abrasive optimized for aggressive stock removal and weld grinding\u003c\/li\u003e\n\u003cli\u003eRated to 30000 RPM for use on high-speed angle grinders and disc sanders\u003c\/li\u003e\n\u003cli\u003eStiff fibre backing with strong resin bond provides tear resistance under heavy load\u003c\/li\u003e\n\u003cli\u003eRoloca attachment system secures disc to back-up pad without tools for fast disc changes\u003c\/li\u003e\n\u003cli\u003eLong-lasting abrasive mineral helps extend disc life and reduce per-part cost\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Roloca-compatible back-up pads on angle grinders and disc sanders accepting 3 inch fibre discs.

Confirm the tool spindle speed does not exceed the 30000 RPM disc rating before operation. Inspect the disc and back-up pad for damage before each use and replace any disc showing tears, cracks, or delamination. Abrasive disc use on grinders is governed by ANSI B7.1 and relevant OSHA standards — ensure guards are in place and appropriate PPE including eye and face protection is worn at all times.\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: 60\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: Precision Shaped Grain, Coated\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: Roloca\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0135 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUOM\u003c\/strong\u003e: Each\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: 7100100885\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51346692899122,"sku":"7100100885","price":618.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310536067.jpg?v=1782087751","url":"https:\/\/voomisupply.com\/products\/3m-7100100885-roloca-782c-fibre-disc-3-inch-60-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
