It uses aluminum oxide abrasive at a fine 120 grit rating, making it well suited for finishing passes where controlled material removal and a consistent surface profile are required. The roll measures 0.5 inches in diameter. Machinists, tool-and-die workers, and metal fabricators reach for this style of roll when a standard flap wheel or drum sander cannot reach the workpiece geometry.\u003c\/p\u003e\u003cp\u003eStraight cartridge rolls like this one are standard consumables in metalworking shops handling stainless steel, carbon steel, aluminum, and cast iron. They fit mandrel-driven spindle tools, die grinders, and bench-mounted finishing machines. Common applications include port work, weld bead blending inside tubing, and finish work on internal radii. The fine grit is particularly useful in the final stages of surface prep before inspection or coating.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAluminum oxide abrasive provides consistent cut rate and long service life on ferrous and non-ferrous metals\u003c\/li\u003e\n\u003cli\u003e120 grit fine grade delivers smooth surface finish while still removing light burrs and tooling marks\u003c\/li\u003e\n\u003cli\u003e0.5 inch diameter fits standard small-bore mandrels used in die grinders and finishing machines\u003c\/li\u003e\n\u003cli\u003eStraight cartridge roll geometry reaches tight internal features that flat or drum abrasives cannot access\u003c\/li\u003e\n\u003cli\u003eSold individually — order in multiples of 100 to meet minimum order quantity requirements\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with mandrel-driven rotary tools and die grinders that accept 0.5 inch diameter straight cartridge rolls.

Ensure the spindle tool is powered off and locked out before mounting or removing the roll. Do not exceed the maximum RPM rating of the mandrel or the tool. Wear appropriate eye and face protection during operation as abrasive debris and fragmented grit are hazards at operating speed.\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: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRoll Style\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\u003eMinimum Order Quantity\u003c\/strong\u003e: 100\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.015 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: 08834180291\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERIT","offers":[{"title":"Default Title","offer_id":51563623579954,"sku":"08834180291","price":5678.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6a4e71efbcf1ec3a1cff4cd9cd4403ca.jpg?v=1786499921","url":"https:\/\/voomisupply.com\/products\/merit-abrasives-08834180291-cartridge-roll-120-grit-1-2-in","provider":"Voomi Supply","version":"1.0","type":"link"}
