At 12 inches in diameter with a 1-1\/4 inch arbor hole, this medium-grade disc mounts via a standard arbor connection and operates at a maximum rated speed of 1900 RPM. It is used to remove burrs, sharp edges, and surface irregularities from ferrous and non-ferrous metal parts. Fabricators, machinists, and maintenance technicians working in industrial or commercial shops are the typical installers and operators of this disc.\u003c\/p\u003e\u003cp\u003eThis disc is suited for bench-mounted or floor-standing disc grinders in manufacturing, job shop, and maintenance-repair-operations environments. Its medium grade makes it appropriate for general deburring work where moderate material removal is needed without aggressive stock removal. The aluminum oxide abrasive provides consistent cut performance on steel, aluminum, and similar metals. It is sold and packaged individually.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e12 inch diameter provides wide surface contact for efficient deburring passes\u003c\/li\u003e\n\u003cli\u003e1-1\/4 inch arbor hole fits standard disc grinder arbor configurations\u003c\/li\u003e\n\u003cli\u003eMedium grade aluminum oxide abrasive for controlled material removal on metal edges and surfaces\u003c\/li\u003e\n\u003cli\u003eRated to 1900 RPM maximum for safe operation on compatible machines\u003c\/li\u003e\n\u003cli\u003eArbor connector type for secure, centered disc mounting\u003c\/li\u003e\n\u003cli\u003eMaroon disc color consistent with medium-grade abrasive identification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on disc grinders and similar machines equipped with a 1-1\/4 inch arbor, accepting a 12 inch diameter deburring disc rated to 1900 RPM or below.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eAlways power down and lock out the grinder before mounting or removing the disc. Verify the machine's maximum operating RPM does not exceed the disc's 1900 RPM rating before use. Mounting should be performed by a qualified operator following the grinder manufacturer's instructions and applicable ANSI B11 or OSHA 1910.215 machine guarding requirements. Inspect the disc for damage before each use and do not operate a cracked or visibly damaged disc.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter Hole Size\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Medium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnector Type\u003c\/strong\u003e: Arbor\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 1900\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Maroon\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.48 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 7100078403\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51691210899762,"sku":"7100078403","price":42.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1b2109cca91caa78107585e0d5874ffb.jpg?v=1788281586","url":"https:\/\/voomisupply.com\/products\/3m-7100078403-deburring-disc-12in-medium-aluminum-oxide","provider":"Voomi Supply","version":"1.0","type":"link"}
