Built with an aluminum oxide abrasive on a heavy cloth backing (X-weight), it runs at 150 grit for a very fine finish that smooths surfaces without aggressive stock removal. The band measures 3 inches in diameter by 3 inches wide and mounts on a rubber expander drum for use with drills, die grinders, or rotary tools. Machinists, fabricators, and finishing trades rely on this style of band for bore finishing, contour sanding, and weld blending in both shop and field settings.\u003c\/p\u003e\n\u003cp\u003eThis spiral band suits applications where consistent swirl-free finish quality matters on cylindrical or contoured workpieces. Typical uses include deburring drilled holes, blending weld seams on tubular stock, and final-pass surface conditioning before coating or assembly. The aluminum oxide abrasive cuts consistently across ferrous and non-ferrous metals as well as hardwoods and engineered composites. It fits standard 3-inch expander drum setups common in metalworking and woodworking shops.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum oxide abrasive for consistent cut on metal, wood, and composite surfaces\u003c\/li\u003e\n  \u003cli\u003e150 grit very fine grade for finish sanding and surface conditioning\u003c\/li\u003e\n  \u003cli\u003eX-weight cloth backing provides durability and conformability on curved surfaces\u003c\/li\u003e\n  \u003cli\u003e3 inches diameter by 3 inches wide fits standard expander drum setups\u003c\/li\u003e\n  \u003cli\u003eSpiral construction reduces loading and extends band life during use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 3-inch rubber expander drums mounted on drills, die grinders, or rotary power tools.

Ensure the drum diameter matches the band interior diameter for a secure, slip-free fit. Always power down and de-energize the tool before installing or removing the band. Operate within the maximum RPM rating of both the drum and the host tool to prevent band failure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Type\u003c\/strong\u003e: Coated\u003c\/li\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: 150\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Very Fine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: Cloth\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Weight\u003c\/strong\u003e: X\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: 7010508240\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51538997969202,"sku":"7010508240","price":284.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fadd0332e52c48e92c658b3cf2c69f56_eb9d47fc-4216-498b-8124-fdc6a9ee8bb1.jpg?v=1785832288","url":"https:\/\/voomisupply.com\/products\/3m-7010508240-spiral-band-150-grit-aluminum-oxide-3x3-in","provider":"Voomi Supply","version":"1.0","type":"link"}
