It uses 3M Precision Shaped Grain bonded to an X-weight polyester-cotton cloth backing, producing fast, consistent cuts at up to 15000 RPM. A built-in grinding aid reduces heat buildup during use, which helps prevent surface discoloration and extends disc life. The resin bond system resists heat to maintain grain integrity under sustained load. This disc is suited for fabrication and finishing work performed by metalworkers, welders, and grinding technicians working with demanding alloys.\u003c\/p\u003e\u003cp\u003eThe 947A disc is designed for medium to high pressure grinding applications. It performs on stainless steel, carbon steel, cobalt chrome, nickel alloys, and other exotic alloys where heat control and cut rate are both critical. The Hookit attachment system allows quick disc changes without tools, making it practical for production environments where downtime between disc swaps adds up. At 3 inches in diameter with 80 grit, it fits compact right-angle grinders and die grinders used in tight clearance work and detail grinding.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePrecision Shaped Grain delivers fast stock removal and consistent cut performance\u003c\/li\u003e\n\u003cli\u003eHookit hook-and-loop attachment allows tool-free disc changes and disc reuse\u003c\/li\u003e\n\u003cli\u003eX-weight polyester-cotton cloth backing handles aggressive sanding pressure without tearing\u003c\/li\u003e\n\u003cli\u003eGrinding aid reduces heat and lowers grinding temperatures on metal surfaces\u003c\/li\u003e\n\u003cli\u003eResin bond resists heat buildup and helps prevent workpiece discoloration\u003c\/li\u003e\n\u003cli\u003eRated to 15000 RPM for use with standard compact angle grinders and die grinders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Hookit-compatible backup pads and right-angle grinders or die grinders accepting 3-inch discs.

Verify the grinder spindle speed does not exceed the 15000 RPM disc rating before operation. Allow the tool to reach full speed before contacting the workpiece, and keep the disc moving to avoid localized heat buildup. Worn or damaged discs should be removed from service immediately.\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 Type\u003c\/strong\u003e: Precision Shaped Grain\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\u003eBond Type\u003c\/strong\u003e: Resin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.56 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 6.88 inches x 6.88 inches 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: 7100113126\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51343356657970,"sku":"7100113126","price":267.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310535737.jpg?v=1782020845","url":"https:\/\/voomisupply.com\/products\/3m-7100113126-cubitron-ii-hookit-disc-3-inch-80-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
