Built with aluminum oxide abrasive on a cloth backing, it delivers consistent stock removal at 40 grit — a coarse grade suited for aggressive material removal in tight bores, tubes, and contoured surfaces. At 0.75 inches in diameter, it mounts to a mandrel and is driven by die grinders or drill presses. This roll is a standard tool in metal fabrication, aerospace finishing, and general maintenance shops where controlled inside-diameter work is required.\u003c\/p\u003e\n\u003cp\u003eThis cartridge roll is used in applications requiring abrasive work inside bores, ports, holes, and other confined geometries. The coarse 40 grit rating makes it appropriate for initial material removal passes before progressing to finer grits. Typical use cases include weld cleanup, rust removal, and blending transitions in metal pipe, tubing, and castings. It is commonly used by machinists, fabricators, and maintenance technicians working on both ferrous and non-ferrous metals.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum oxide abrasive for durable, consistent cutting action on metal surfaces\u003c\/li\u003e\n  \u003cli\u003eCoarse 40 grit rating suited for aggressive initial stock removal\u003c\/li\u003e\n  \u003cli\u003eCloth backing provides flexibility and conformability in contoured or curved surfaces\u003c\/li\u003e\n  \u003cli\u003e0.75 inch diameter fits standard cartridge roll mandrels for die grinders and drill presses\u003c\/li\u003e\n  \u003cli\u003eRated to a maximum of 16,000 RPM for safe operation at high speeds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard consumable for use with cartridge roll mandrels compatible with 0.75 inch diameter straight cartridge rolls in die grinders and drill press setups.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or maintenance technicians using appropriate mandrel hardware. Ensure the mandrel size matches the cartridge roll core before mounting. Always confirm the tool RPM does not exceed the 16,000 RPM maximum rating of this roll before operation. Inspect the roll for wear or separation before each use and replace if the abrasive or cloth backing shows signs of degradation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\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: Coarse\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 40\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: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 16,000 RPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31191516\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: 7010327470\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51542519873842,"sku":"7010327470","price":212.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dc43df6dbfc959f4b1991eba1fa1b257_fd2b6371-cd5c-45e8-834e-ee949b96a072.jpg?v=1785902707","url":"https:\/\/voomisupply.com\/products\/3m-7010327470-straight-cartridge-roll-40-grit-aluminum-oxide","provider":"Voomi Supply","version":"1.0","type":"link"}
