Built on an X-weight polyester-cotton cloth backing, this 3-inch diameter disc uses 3M Precision Shaped Grain technology to cut faster and last longer than conventional abrasive grains. The 60-grit cut rating and integrated grinding aid make it well suited for medium to high pressure grinding applications. It is rated to 15000 RPM and handles stainless steel, carbon steel, cobalt chrome, nickel alloys, and other exotic alloys. Metal fabricators, welders, and industrial maintenance technicians are the primary installers and users of this disc.\u003c\/p\u003e\u003cp\u003eThis disc is built for production-level grinding and blending in fabrication shops, manufacturing facilities, and industrial maintenance environments. The Hookit attachment system allows the disc to be mounted and removed quickly from compatible random orbital and disc sanders, reducing changeover time during high-volume work. It is appropriate for both flat-surface grinding and edge work on hard metals where heat buildup and surface discoloration are concerns. The grinding aid chemistry actively reduces friction-generated heat, helping protect workpiece integrity on heat-sensitive alloys.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePrecision Shaped Grain construction cuts faster than conventional abrasive grain, increasing throughput\u003c\/li\u003e\n\u003cli\u003eHookit hook-and-loop attachment system enables fast disc changes and disc reuse over the full service life\u003c\/li\u003e\n\u003cli\u003eX-weight polyester-cotton cloth backing withstands aggressive grinding pressure without tearing\u003c\/li\u003e\n\u003cli\u003eIntegrated grinding aid reduces heat buildup and lowers grinding temperatures at the contact zone\u003c\/li\u003e\n\u003cli\u003eResin bond system resists heat and helps prevent surface discoloration on finished metal\u003c\/li\u003e\n\u003cli\u003e60-grit designation suited for medium to high stock removal on ferrous and non-ferrous metals\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on stainless steel, carbon steel, cobalt chrome, nickel alloys, and other exotic alloys.

Verify that the tool spindle speed does not exceed the 15000 RPM rating marked on the disc before operation. Use a compatible Hookit backup pad to ensure full surface contact and secure attachment. Always wear appropriate PPE including eye protection, gloves, and hearing protection when operating grinding equipment.\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: 60\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\u003eAttachment Type\u003c\/strong\u003e: Hookit hook-and-loop\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 2.96 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 6.88 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 6.88 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 5.88 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: 076308457001\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: 7100113109\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51345964499250,"sku":"7100113109","price":291.76,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310535739.jpg?v=1782067743","url":"https:\/\/voomisupply.com\/products\/3m-7100113109-cubitron-ii-hookit-disc-947a-3-inch-60-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
