It uses a non-woven aluminum oxide construction with a medium grade cut, making it suitable for deburring, cleaning weld areas, and light stock removal without leaving deep scratch patterns. The Type R (Roloc TR) attaching system allows fast one-handed disc changes, reducing downtime during production or service work. Maximum rated speed is 18,000 RPM. The disc measures 3 inches in diameter and ships in a 100-disc package. Color is maroon with a black center button.\u003c\/p\u003e\u003cp\u003eThis disc is used in metal fabrication, HVAC sheet metal work, automotive body preparation, and general industrial surface conditioning. The non-woven construction provides consistent cut throughout the life of the disc, conforming to contoured surfaces better than coated abrasive alternatives. It is well suited to applications where surface finish control matters — such as preparing metal for coating, removing light rust or oxidation, or cleaning up welds before inspection. Licensed trades working with ductwork, structural steel, or copper pipe frequently use quick-change discs of this type with right-angle die grinders or drill-driver tools equipped with a Roloc TR mandrel.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType R (Roloc TR) quick-change attaching system for fast one-handed disc swaps\u003c\/li\u003e\n\u003cli\u003eAluminum oxide non-woven construction — medium grade for blending and surface conditioning\u003c\/li\u003e\n\u003cli\u003e3 inch diameter fits standard Roloc TR mandrels on right-angle grinders and die grinders\u003c\/li\u003e\n\u003cli\u003e18,000 RPM maximum rated speed for use with common air and electric rotary tools\u003c\/li\u003e\n\u003cli\u003eMaroon color designation consistent with medium-grade non-woven abrasive classification\u003c\/li\u003e\n\u003cli\u003e100-disc package quantity reduces restocking frequency on active job sites\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Type R (Roloc TR) quick-change mandrels.

Always verify the tool's no-load RPM does not exceed the 18,000 RPM disc rating before operating. Inspect each disc for damage before mounting and ensure the disc is fully seated and locked onto the mandrel prior to startup. Eye protection and appropriate PPE are required; follow applicable ANSI B11 and shop safety standards when operating rotary abrasive tooling.\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\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstruction\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\u003eAttaching System\u003c\/strong\u003e: Type R (Roloc TR)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 18,000\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: Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: SC-DR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 100 discs\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3 pounds\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: 00222851\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51541714501938,"sku":"00222851","price":674.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/085dbf650767d718e48fbad7d9eecae9.jpg?v=1785882813","url":"https:\/\/voomisupply.com\/products\/3m-00222851-quick-change-disc-3-in-aluminum-oxide-100-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
