Built with aluminum oxide abrasive at 120 grit (fine grade), it delivers consistent stock removal and surface refinement on ferrous and non-ferrous metals. The 3\/8 inch diameter profile fits standard mandrels used in die grinders and rotary tools. Machinists, tool-and-die technicians, and metal fabricators reach for this roll when working bores, slots, ports, and other confined geometries where flat abrasives cannot reach.\u003c\/p\u003e\u003cp\u003eThis cartridge roll is suited for deburring, blending, and finishing operations in job shops, maintenance facilities, and production environments. The fine 120-grit aluminum oxide construction makes it appropriate for final-pass surface preparation before inspection or coating. It is sold individually and is available in multiples of 100 units, making it practical for ongoing production use where abrasive consumption is high.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e120 grit aluminum oxide abrasive for fine-grade material removal and surface blending\u003c\/li\u003e\n\u003cli\u003eStraight cartridge profile maintains consistent contact in cylindrical and contoured workpieces\u003c\/li\u003e\n\u003cli\u003e3\/8 inch diameter fits standard mandrel shanks used with die grinders and rotary tools\u003c\/li\u003e\n\u003cli\u003eAluminum oxide construction provides durability across a range of ferrous and non-ferrous metals\u003c\/li\u003e\n\u003cli\u003eFine grade finish reduces surface roughness prior to coating, inspection, or assembly\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard mandrels compatible with 3\/8 inch diameter straight cartridge rolls, typically driven by die grinders, pencil grinders, or rotary tools accepting the appropriate shank size.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eA licensed machinist or metal fabricator should mount the cartridge roll onto a compatible mandrel per the mandrel manufacturer's torque and seating instructions. Always confirm the tool RPM rating does not exceed the abrasive roll's rated maximum speed before operation. Wear appropriate eye and face protection, and secure the workpiece before applying the roll. Inspect the roll for tears or unraveling before each use and discard any damaged rolls immediately.\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\u003eDiameter\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRoll Profile\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: STANDARD ABRASIVES\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7100092850\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51540725039410,"sku":"7100092850","price":76.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a7705ca041980875316ae4307d1e2b60.jpg?v=1785863036","url":"https:\/\/voomisupply.com\/products\/standard-abrasives-7100092850-cartridge-roll-3-8-in-120-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
