It uses 3M Precision Shaped Grain on an X-weight polyester-cotton cloth backing to deliver fast, consistent cuts under medium to high pressure. The disc measures 3 inches in diameter and is rated at 15000 RPM. A built-in grinding aid reduces heat buildup at the work surface. Resin bonding resists heat and helps prevent discoloration of the workpiece. This disc is suited to metal fabrication, weld blending, and surface prep work performed by welders, fabricators, and finishing technicians.\u003c\/p\u003e\u003cp\u003eThe 947A disc is built for medium to high pressure grinding applications where heat control and cut rate are both critical. It is commonly used on grinders and sanders in fabrication shops, aerospace component finishing, and heavy industrial maintenance. The Hookit attachment system allows fast disc changes without removing the backing pad, reducing downtime during continuous production runs. It fits standard Hookit-compatible backup pads used on random orbital and disc-style pneumatic or electric tools.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePrecision Shaped Grain delivers fast cut rates and extended disc life on hard alloys\u003c\/li\u003e\n\u003cli\u003eHookit attachment system enables tool-free disc changes and reuse throughout disc life\u003c\/li\u003e\n\u003cli\u003eX-weight polyester-cotton cloth backing withstands aggressive sanding pressure\u003c\/li\u003e\n\u003cli\u003eBuilt-in grinding aid reduces heat generation during metal removal\u003c\/li\u003e\n\u003cli\u003eResin bond resists heat and minimizes workpiece discoloration\u003c\/li\u003e\n\u003cli\u003eRated at 15000 RPM for use with compatible high-speed grinders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Hookit-compatible backup pads on pneumatic or electric disc grinders and random orbital sanders rated for 3 inch abrasive discs at or below 15000 RPM.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and disc changes should be performed with the grinder powered off and disconnected from the air supply or electrical source. Verify that the backup pad is rated for the tool speed before mounting the disc. Inspect the disc for damage before each use and do not exceed the 15000 RPM maximum rated speed. Follow applicable ANSI B7 abrasive safety standards and the tool and disc manufacturer guidelines for safe operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 80\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Speed\u003c\/strong\u003e: 15000 RPM\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 Grain\u003c\/strong\u003e: Precision Shaped Grain\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 2.528 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 6.88 x 6.88 x 5.88 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\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: 7100113145\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51343991079218,"sku":"7100113145","price":267.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310535756.jpg?v=1782026305","url":"https:\/\/voomisupply.com\/products\/3m-7100113145-cubitron-ii-hookit-disc-3-inch-80-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
