The disc uses fast-cutting aluminum oxide abrasive grains bonded to a heavyweight YF-weight polyester cloth backing with heat-resistant resin. Rated to 20000 RPM, it delivers consistent material removal under medium-pressure applications. The Roloc attachment system allows for efficient, tool-free disc changes directly on compatible right-angle grinders and die grinders. Suitable for both wet and dry use, it is a practical choice for metal fabrication and surface prep work handled by welders, machinists, and metal finishing technicians.\u003c\/p\u003e\n\u003cp\u003eThis disc is used in light industrial and fabrication environments where fast stock removal and surface conditioning on metal are required. Common applications include weld seam blending, edge deburring, and pre-paint surface finishing on ferrous and non-ferrous metals. The P120 grit rating places it in the fine range, making it well suited for finishing passes rather than heavy material removal. It arrives packaged in box quantity and is compatible with standard Roloc-style quick-change mandrels used on pneumatic and electric angle grinders.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRoloc quick-change attachment allows fast, secure disc installation and removal without tools\u003c\/li\u003e\n  \u003cli\u003eAluminum oxide abrasive grains provide fast cutting action across a wide range of metal surfaces\u003c\/li\u003e\n  \u003cli\u003eYF-weight polyester cloth backing supports medium-pressure grinding and finishing passes\u003c\/li\u003e\n  \u003cli\u003eHeat-resistant resin bond maintains abrasive integrity under pressure, heat, and wet conditions\u003c\/li\u003e\n  \u003cli\u003eRated to 20000 RPM for use with standard pneumatic and electric die grinders and angle grinders\u003c\/li\u003e\n  \u003cli\u003eCompatible with both wet and dry application environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard Roloc-style quick-change mandrels on pneumatic and electric right-angle grinders and die grinders.

Thread the Roloc disc onto a compatible quick-change mandrel until seated securely before operating. Verify the tool RPM rating meets or exceeds the 20000 RPM disc rating before use. Personal protective equipment including eye protection and gloves is required during abrasive disc operations per standard shop safety practice.\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\u003eGrit\u003c\/strong\u003e: P120\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Type\u003c\/strong\u003e: YF-Weight Polyester Cloth\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Heat-Resistant Resin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMax Speed\u003c\/strong\u003e: 20000 RPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Wet or Dry\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.938 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00051144224067\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: 3M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7000000389\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51345767858482,"sku":"7000000389","price":343.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310534279.jpg?v=1782062443","url":"https:\/\/voomisupply.com\/products\/3m-7000000389-roloc-361f-disc-3-inch-p120-grit-aluminum-oxide","provider":"Voomi Supply","version":"1.0","type":"link"}
