Built on an X-weight cloth backing with resin bonding, it delivers consistent cut rate and heat resistance through demanding abrasive cycles. The roll measures 0.75 inches in diameter by 1.5 inches in length with a 0.125-inch arbor hole, and runs at 80 grit for moderate-to-aggressive stock removal. Machinists, fabricators, and finishing technicians use this roll where a mounted abrasive is required in a die grinder or rotary tool setup.\u003c\/p\u003e\u003cp\u003eThis cartridge roll is suited for internal diameter grinding, port matching, weld blending, and edge deburring on ferrous and non-ferrous metals. The X-weight cloth backing resists tearing under lateral pressure, making it appropriate for contoured surfaces and tight bores where flat abrasives cannot reach. It is sold in minimum quantities of 100 rolls per order, consistent with production-volume shop use.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAluminum oxide abrasive mineral for reliable cut on steel, cast iron, and aluminum\u003c\/li\u003e\n\u003cli\u003eX-weight cloth backing provides durability and resistance to tearing under load\u003c\/li\u003e\n\u003cli\u003eResin bond construction enhances heat resistance during extended grinding cycles\u003c\/li\u003e\n\u003cli\u003e80 grit for moderate stock removal and surface blending\u003c\/li\u003e\n\u003cli\u003eCompact 0.75 inches x 1.5 inches x 0.125 inches form factor fits standard cartridge roll mandrels\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard cartridge roll mandrels in die grinders and rotary tools that accept a 0.125-inch arbor shaft.

Ensure the grinder is powered off and disconnected from the air or electrical supply before mounting or removing the roll. Do not exceed the maximum RPM rating marked on the roll or mandrel. Inspect the roll for damage before each use and replace if tearing, separation, or uneven wear is observed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Mineral\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: 80\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eArbor Hole\u003c\/strong\u003e: 0.125 inches\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: 00051144140299\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 7010309043\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51345209229618,"sku":"7010309043","price":163.78,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310533996.jpg?v=1782051547","url":"https:\/\/voomisupply.com\/products\/3m-7010309043-aluminum-oxide-cartridge-roll-80-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
