Built with aluminum oxide abrasive on a cloth backing, this roll delivers consistent cutting action at very fine 320 grit. The 3\/16 inch diameter profile fits mandrel-driven rotary tools and die grinders commonly used by machinists, fabricators, and maintenance technicians. With a maximum operating speed of 24,000 RPM, it suits high-speed finishing passes where surface quality matters. This cartridge roll is sold individually but requires a minimum order of 100 units per purchase.\u003c\/p\u003e\u003cp\u003eThis cartridge roll is suited for deburring, blending, and surface finishing on metal, wood, and composite materials. The very fine 320 grit produces smooth finishes appropriate for pre-paint prep, weld blending, and final-stage material removal. The straight cartridge profile works in portable die grinders, pencil grinders, and bench-mounted spindle tools. It is commonly specified in production environments, tool-and-die shops, and MRO maintenance applications where consistent surface finish is required across repeated operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e320 grit aluminum oxide abrasive for very fine surface finishing\u003c\/li\u003e\n\u003cli\u003eCloth backing provides durability and flexibility during contour grinding\u003c\/li\u003e\n\u003cli\u003e3\/16 inch diameter fits standard mandrels for die grinders and rotary tools\u003c\/li\u003e\n\u003cli\u003eRated to 24,000 RPM for use with high-speed pneumatic and electric grinders\u003c\/li\u003e\n\u003cli\u003eStraight cartridge form maintains consistent contact on flat and slightly curved surfaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard consumable for use with mandrel-driven rotary grinding tools that accept 3\/16 inch diameter straight cartridge rolls.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists, fabricators, or maintenance technicians familiar with rotary abrasive tooling. Ensure the die grinder or rotary tool is powered off and air supply is disconnected before mounting the cartridge roll onto the mandrel. Do not exceed the rated maximum speed of 24,000 RPM. Inspect the roll for damage before use and follow applicable ANSI abrasive safety standards for grinding wheel operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 320\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Very Fine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: Cloth\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Diameter\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 24,000\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 100\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31191516\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: 7010309062\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51542541140274,"sku":"7010309062","price":89.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bddf153b2ec804667fb2407d013aada3.jpg?v=1785903205","url":"https:\/\/voomisupply.com\/products\/3m-7010309062-straight-cartridge-roll-320-grit-3-16-in","provider":"Voomi Supply","version":"1.0","type":"link"}
