Built on an X-weight polyester-cotton cloth backing, the disc uses 3M Precision Shaped Grain technology to cut faster and last longer than conventional abrasive grains. A built-in grinding aid reduces heat buildup at the workpiece surface, and a resin bond system resists thermal degradation to minimize discoloration. At 6 inches in diameter and 40 grit, this disc is suited for stock removal and blending work in fabrication and finishing environments. Metal fabricators, weld grinders, and production operators are the primary installers and users.\u003c\/p\u003e\n\u003cp\u003eThis disc is intended for medium to high pressure grinding and blending applications on stainless steel, carbon steel, nickel alloys, cobalt chrome, and other exotic alloys. The Hookit attachment system allows fast disc changes without tools, making it practical for high-volume production environments where downtime between disc changes must be minimized. It is well suited for angle grinder and right-angle sander applications in metal fabrication shops, aerospace component finishing, and welding operations where heat-sensitive materials require controlled grinding temperatures.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePrecision Shaped Grain delivers fast, consistent cut rates across the disc life\u003c\/li\u003e\n  \u003cli\u003eX-weight polyester-cotton cloth backing provides durability under aggressive pressure\u003c\/li\u003e\n  \u003cli\u003eBuilt-in grinding aid actively reduces heat and lowers grinding temperatures at the workpiece\u003c\/li\u003e\n  \u003cli\u003eResin bond resists heat to prevent workpiece discoloration during extended use\u003c\/li\u003e\n  \u003cli\u003eHookit attachment system enables tool-free disc changes and disc reuse\u003c\/li\u003e\n  \u003cli\u003e40 grit designation targets heavy stock removal and initial blending passes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Hookit-compatible random orbital sanders and angle grinders accepting 6-inch hook-and-loop discs.

Ensure the tool is powered off and unplugged before mounting or removing the disc. Verify the tool's maximum RPM rating meets or exceeds the disc's rated speed before operation. Inspect the Hookit backing pad for wear before each disc change to ensure secure attachment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: X-weight polyester-cotton cloth\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Type\u003c\/strong\u003e: Precision Shaped Grain with grinding aid\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Resin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAttachment Type\u003c\/strong\u003e: Hookit hook-and-loop\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 13.16 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 23.8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 6.9 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 7.3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 076308457193\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: 7100113143\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51344671768882,"sku":"7100113143","price":1141.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310535795.jpg?v=1782039878","url":"https:\/\/voomisupply.com\/products\/3m-7100113143-cubitron-ii-hookit-947a-disc-6-inch-40-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
