Built on an X-weight cloth backing, it delivers the durability needed for aggressive material removal without premature breakdown. The abrasive is aluminum oxide, resin bonded for heat resistance, and graded at P120 — a fine grit well suited for blending, deburring, and light stock removal. The roll measures 1\/2 inch wide, 1 inch in length, and 1\/8 inch in diameter, making it a compact tool for tight-tolerance finishing work. Installation requires a matching mandrel and a rotary tool, die grinder, or similar powered spindle. Machinists, metal fabricators, and toolroom technicians are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis cartridge roll is used in metalworking, fabrication shops, and maintenance applications where standard flat abrasives cannot conform to the workpiece geometry. It is well matched for deburring drilled holes, blending weld seams in confined areas, and finishing curved or contoured metal surfaces. The tapered profile allows access to angled recesses and chamfered edges that straight-shank abrasives cannot reach. At P120 grit, it is appropriate for intermediate finishing passes after coarser stock removal is complete.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum oxide abrasive grain for consistent cut rate on ferrous and non-ferrous metals\u003c\/li\u003e\n  \u003cli\u003eX-weight cloth backing provides high tensile strength and resistance to tearing under load\u003c\/li\u003e\n  \u003cli\u003eResin bond construction resists heat buildup during extended grinding operations\u003c\/li\u003e\n  \u003cli\u003eFull tapered profile reaches angled recesses, slots, and contoured surfaces\u003c\/li\u003e\n  \u003cli\u003eP120 grit delivers a balance of material removal and surface finish quality\u003c\/li\u003e\n  \u003cli\u003eCompact 1\/2 inch x 1 inch x 1\/8 inch size fits standard cartridge roll mandrels\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard cartridge roll mandrels on die grinders, rotary tools, and similar spindle-driven equipment rated for the appropriate RPM of this roll size.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by threading the roll onto a compatible mandrel and tightening per the mandrel manufacturer's specifications. Always verify the tool's rated RPM does not exceed the maximum rated speed of the abrasive before operation. Wear appropriate eye protection and gloves during installation and use. Inspect the roll for tears, separation, or uneven wear before each use and replace if damage is found.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 341D\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Type\u003c\/strong\u003e: X-Weight Cloth\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Resin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: P120\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 1\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Roll\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00051144972593\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: 7100085779\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51346596790578,"sku":"7100085779","price":141.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310535057.jpg?v=1782084856","url":"https:\/\/voomisupply.com\/products\/3m-7100085779-tapered-cartridge-roll-p120-1-2x1x1-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
