It combines 3M ceramic abrasive grain with aluminum oxide to deliver a self-sharpening mineral blend that maintains a consistent cut rate over the life of the disc. The disc measures 3 inches in diameter and carries a 36-grit rating, placing it in the coarse cutting range. A heat-resistant resin bonds the abrasive to a heavy polyester backing rated for medium-pressure use. Licensed trades and fabrication shops rely on this disc for metalworking tasks where heat management and abrasive longevity are priorities.\u003c\/p\u003e\u003cp\u003eThis disc is suited for use on heat-sensitive alloys including stainless steel, nickel alloys, and titanium, where the built-in grinding aid helps reduce grinding temperatures and minimize workpiece damage. The Roloca attachment system allows quick disc changes on compatible random orbital and disc grinders. It performs in both wet and dry environments, making it practical across a range of shop and field conditions. Typical users include metal fabricators, welders, and maintenance trades working on ferrous and non-ferrous materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCeramic and aluminum oxide blend self-sharpens for improved durability and cut rate over aluminum oxide alone\u003c\/li\u003e\n\u003cli\u003e36-grit coarse abrasive suited for aggressive stock removal\u003c\/li\u003e\n\u003cli\u003e3-inch diameter fits compact disc grinders and random orbital tools with Roloca-compatible backing pads\u003c\/li\u003e\n\u003cli\u003eHeavy polyester backing supports medium-pressure applications in both wet and dry conditions\u003c\/li\u003e\n\u003cli\u003eGrinding aid reduces heat buildup when working stainless steel, nickel alloys, and titanium\u003c\/li\u003e\n\u003cli\u003eHeat-resistant resin bonding holds abrasive securely under pressure, heat, and moisture\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Roloca-compatible disc grinders and backing pads that accept 3-inch coated abrasive discs.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMounting and disc changes should be performed with the grinder powered off and disconnected from its power source. Verify the backing pad is rated for the disc diameter and operating speed before attaching. Follow applicable ANSI and tool manufacturer guidelines for abrasive wheel mounting and maximum RPM compliance. Inspect the disc for damage before each use and discard any disc showing tears, perforations, or delamination.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 36\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Type\u003c\/strong\u003e: Ceramic blended with aluminum oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: Heavy polyester\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Heat-resistant resin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Wet and dry\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00051144766314\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: 7000028339\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51342947877170,"sku":"7000028339","price":435.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310534585.jpg?v=1782011565","url":"https:\/\/voomisupply.com\/products\/3m-7000028339-coated-abrasive-disc-36-grit-3-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
