It uses 3M Precision Shaped Grain, a structured abrasive mineral that delivers higher cut rates and a cooler grinding action compared to conventional fibre discs. The disc incorporates a grinding aid that reduces heat buildup at the workpiece surface, making it well suited for heat-sensitive alloys including stainless steel and high nickel alloys. A stiff fibre backing paired with a strong resin bond gives the disc resistance to tearing under heavy load. It is installed on compatible disc pad face plates and hubs using a 7\/8 inch arbor and is sized at 4.5 inches in diameter.\u003c\/p\u003e\u003cp\u003eThis disc is designed for professional metal fabrication and maintenance applications where aggressive material removal and surface refinement must be performed on stainless steel and high nickel alloys. Typical tasks include weld removal, weld blending, beveling, edge chamfering, and finish refinement. Its 120 grit rating makes it appropriate for blending and finishing passes following heavier grinding operations. Fabricators, pipefitters, and industrial maintenance technicians working on stainless assemblies will find this disc well matched to those demands.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3M Precision Shaped Grain delivers higher cut rates and cooler grinding than conventional fibre disc abrasives\u003c\/li\u003e\n\u003cli\u003eGrinding aid minimizes heat generation, protecting heat-sensitive alloys like stainless steel and high nickel alloys\u003c\/li\u003e\n\u003cli\u003e120 grit rating suited for weld blending, beveling, edge chamfering, and finish refinement\u003c\/li\u003e\n\u003cli\u003eStiff fibre backing and strong resin bond resist tearing under heavy-load applications\u003c\/li\u003e\n\u003cli\u003e4.5 inch diameter with 7\/8 inch arbor mount for compatibility with standard angle grinders using disc pad face plates and hubs\u003c\/li\u003e\n\u003cli\u003eEach disc is sold individually; minimum order quantity is 100 units\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with 3M disc pad face plates and hubs, sold separately.

Confirm the grinder RPM rating meets or exceeds the disc maximum RPM before mounting. Power down and disconnect the grinder from its power source before changing discs. Always use the appropriate face plate or hub backing pad for this disc size and arbor configuration, and inspect the disc for damage before each use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eArbor Size\u003c\/strong\u003e: 7\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 120\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Type\u003c\/strong\u003e: 3M 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\u003eBond\u003c\/strong\u003e: Resin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 100\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 5.366 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 11.21 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 6.7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 6.95 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 076308896541\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: 7100099280\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51346177884466,"sku":"7100099280","price":429.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310536034.jpg?v=1782073034","url":"https:\/\/voomisupply.com\/products\/3m-7100099280-fibre-disc-4-5-in-120-grit-stainless-grinding","provider":"Voomi Supply","version":"1.0","type":"link"}
