Built on an X-weight cloth backing with resin bonding for heat resistance, this roll measures 0.5 inches wide by 1.5 inches long with a 0.125-inch bore. The ceramic grain abrasive cuts fast and runs cooler than standard aluminum oxide thanks to an integrated grinding aid. Machinists, fabricators, and finishing technicians install these rolls in die grinders and mandrel-based rotary tools for contour grinding, deburring, and weld blending.\u003c\/p\u003e\n\u003cp\u003eThis cartridge roll is suited for use in tight-radius grinding applications where a tapered profile is required to access confined areas or follow curved workpiece geometry. The 60-grit X-weight construction targets medium-to-aggressive stock removal on ferrous metals, stainless steel, and hard alloys. It is commonly used in metalworking shops, maintenance and repair operations, and manufacturing environments where consistent cut rate and abrasive life are critical to throughput.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCeramic grain abrasive for fast cut rate and extended abrasive life\u003c\/li\u003e\n  \u003cli\u003eIntegrated grinding aid reduces heat buildup during use\u003c\/li\u003e\n  \u003cli\u003eResin-bonded X-weight cloth backing resists tearing and deformation under load\u003c\/li\u003e\n  \u003cli\u003eFull tapered profile allows access to contoured and recessed workpiece geometry\u003c\/li\u003e\n  \u003cli\u003e60 grit for medium-to-aggressive stock removal and weld blending\u003c\/li\u003e\n  \u003cli\u003eDimensions: 0.5 inches x 1.5 inches x 0.125 inches bore\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard mandrel-type die grinders and rotary tools that accept 0.125-inch bore cartridge rolls.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThese rolls are installed by a machinist or metalworking technician onto a compatible mandrel secured in a die grinder. Power down and disconnect the tool before mounting or removing the cartridge roll. Ensure the mandrel diameter matches the 0.125-inch bore before seating the roll, and confirm the tool RPM rating does not exceed the maximum rated speed of the abrasive. Eye protection and appropriate PPE are required during operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 747D\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBore Diameter\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 60\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Grain\u003c\/strong\u003e: Ceramic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Weight\u003c\/strong\u003e: X-Weight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: Cloth\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Resin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Roll\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 100\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00051144807864\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: 7100142738\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51345086939442,"sku":"7100142738","price":242.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310534723.jpg?v=1782049384","url":"https:\/\/voomisupply.com\/products\/3m-7100142738-full-tapered-cartridge-roll-747d-60-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
