Built with aluminum oxide abrasive, it delivers consistent stock removal and surface refinement across metal and other hard substrates. At 3\/8 inch in diameter and rated at 180 grit, this roll falls in the very fine grade range, making it suited for finishing passes where surface quality matters. Machinists, tool and die workers, and metal fabricators typically reach for this type of roll when deburring bores, slots, and internal radii with a mandrel-mounted die grinder or drill press.\u003c\/p\u003e\u003cp\u003eThis cartridge roll is appropriate for use on ferrous and non-ferrous metals in both production and job-shop settings. The aluminum oxide grain cuts cleanly on steel, stainless, and aluminum, and holds up well under moderate pressure. The 180 grit level is commonly used for pre-polish finishing, light deburring, and surface prep before coating or inspection. It is well suited for aerospace, automotive, and general metalworking applications where fine surface finish on small-diameter internal features is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAluminum oxide abrasive for reliable cutting action on ferrous and non-ferrous metals\u003c\/li\u003e\n\u003cli\u003e180 grit very fine grade for finishing, light deburring, and pre-polish surface prep\u003c\/li\u003e\n\u003cli\u003e3\/8 inch diameter straight profile fits standard mandrels for die grinders and drill presses\u003c\/li\u003e\n\u003cli\u003eStraight cartridge roll construction maintains consistent contact in bores, slots, and contoured recesses\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.01 pounds per unit, suitable for high-cycle production use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard mandrel tooling sized to accept 3\/8 inch diameter straight cartridge rolls, compatible with die grinders, drill presses, and flex-shaft tools commonly used in metal finishing and fabrication.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation of cartridge rolls is performed by machinists or metalworking technicians using a compatible mandrel. Ensure the mandrel diameter matches the roll bore before mounting, and verify that the tool's RPM rating does not exceed the roll's maximum rated speed. Power down and disconnect the tool from the power source before changing rolls. Inspect the roll for tears or unraveling before each use and replace immediately if damage is found.\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\u003eGrade\u003c\/strong\u003e: Very Fine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 180\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRoll Type\u003c\/strong\u003e: Straight Cartridge Roll\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MERIT ABRASIVES\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 08834180218\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERIT","offers":[{"title":"Default Title","offer_id":51557365711154,"sku":"08834180218","price":5643.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/572060dcfbfe41746a653f852b96b695.jpg?v=1786386678","url":"https:\/\/voomisupply.com\/products\/merit-abrasives-08834180218-cartridge-roll-3-8in-180-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
