Built on the Lockit Type R attaching system, the disc mounts and releases quickly without tools, reducing changeover time during production runs. Rated for up to 20,000 RPM, it handles high-speed angle grinder and die grinder applications without compromising disc integrity. The medium-grade aluminum oxide abrasive provides consistent cut rate across steel, stainless, and aluminum surfaces, while the non-woven construction conforms to irregular profiles and contours. Licensed trades and industrial maintenance technicians are the primary installers and users of this disc.\u003c\/p\u003e\n\u003cp\u003eThis disc is suited for use in metal fabrication shops, HVAC duct work preparation, pipefitting, and general maintenance environments where surface conditioning or light material removal is required. The maroon, medium-grade non-woven construction makes it appropriate for blending welds, removing light oxidation, and prepping surfaces before coating or inspection. It is compatible with Type R quick-change backing pads and mandrels commonly found on right-angle grinders and extended die grinders used across the plumbing, HVAC, and mechanical trades.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3-inch disc diameter fits standard Type R quick-change backing pads\u003c\/li\u003e\n  \u003cli\u003eAluminum oxide abrasive provides durable, consistent cut on ferrous and non-ferrous metals\u003c\/li\u003e\n  \u003cli\u003eNon-woven construction conforms to contours and irregular surfaces for even finishing\u003c\/li\u003e\n  \u003cli\u003eMedium grade balances material removal with surface finish quality\u003c\/li\u003e\n  \u003cli\u003eRated to 20,000 RPM for use with high-speed angle and die grinders\u003c\/li\u003e\n  \u003cli\u003eLockit Type R attaching system allows tool-free disc changes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Type R quick-change backing pads and mandrels on right-angle grinders and die grinders.

Inspect the disc for damage before each use and confirm the grinder RPM rating meets or exceeds 20,000 RPM. Always use appropriate eye protection and follow applicable ANSI B11 and OSHA abrasive wheel safety guidelines. Do not exceed the rated maximum RPM, and ensure the backing pad is properly torqued to the grinder spindle before operation.\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\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Type\u003c\/strong\u003e: Non-Woven\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Medium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 20,000 RPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAttaching System\u003c\/strong\u003e: Type R (Lockit)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: RC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Color\u003c\/strong\u003e: Maroon\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eButton Color\u003c\/strong\u003e: White\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: STANDARD ABRASIVES\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7000046878\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51540522139954,"sku":"7000046878","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ce164f2d0440d966ea866128213cb47c.jpg?v=1785857385","url":"https:\/\/voomisupply.com\/products\/standard-abrasives-7000046878-quick-change-disc-3-in-medium","provider":"Voomi Supply","version":"1.0","type":"link"}
