Built with aluminum oxide abrasive bonded to a cloth backing, it delivers consistent stock removal on ferrous and non-ferrous metals. The 120 grit fine grade makes it well suited for finishing passes where surface smoothness matters more than aggressive material removal. Rated to a maximum of 24,000 RPM, this cartridge roll operates safely at the speeds typical of pneumatic die grinders and rotary tools used in fabrication and maintenance environments.\u003c\/p\u003e\u003cp\u003eThis cartridge roll is used by machinists, tool and die technicians, welders, and metalworkers for finishing inside bores, slots, and weld joints. Its straight profile allows access to cylindrical surfaces and blind holes where flat abrasives cannot reach. Common applications include weld bead blending, edge chamfering, and bore prep in both production shop and field maintenance settings. The cloth backing provides flexibility and durability under repeated load cycles.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAluminum oxide abrasive for consistent cutting on steel, cast iron, and non-ferrous metals\u003c\/li\u003e\n\u003cli\u003e120 grit fine grade suited for finishing and light blending work\u003c\/li\u003e\n\u003cli\u003eCloth backing for flexibility and durability in contoured or cylindrical surfaces\u003c\/li\u003e\n\u003cli\u003eStraight profile for access to bores, slots, and tight internal geometries\u003c\/li\u003e\n\u003cli\u003eRated to 24,000 RPM for compatibility with standard pneumatic die grinders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard straight cartridge roll for use with mandrel-style holders on pneumatic die grinders and rotary tools that accept 5\/16 inch diameter cartridge rolls.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCartridge rolls are installed by a machinist or metalworker onto a compatible tapered or threaded mandrel mounted in a die grinder or rotary tool. Confirm the mandrel diameter matches the 5\/16 inch bore of the roll before use. Always verify the tool RPM does not exceed the 24,000 RPM maximum rating before operating. Wear appropriate eye and face protection, and inspect the roll for damage before each use.\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: 120\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: 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: 5\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 24,000 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\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: 7010299087\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51540160807218,"sku":"7010299087","price":98.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0e32d004e94fbb715dba991c5d6a37ce.jpg?v=1785847525","url":"https:\/\/voomisupply.com\/products\/3m-7010299087-straight-cartridge-roll-120-grit-5-16-in","provider":"Voomi Supply","version":"1.0","type":"link"}
