It uses Re-Engineered Precision Shaped Grain, a proprietary abrasive technology that features sharp, angular structures. These structures continuously fracture to expose fresh cutting points, allowing the disc to run cooler, wear evenly, and maintain aggressive cut rates across its full service life. The result is faster stock removal with less operator pressure compared to conventional abrasive discs. A stiff fiber backing and strong resin bond deliver the durability needed for sustained grinding operations.\u003c\/p\u003e\u003cp\u003eThis disc is suited for medium to high-pressure grinding, weld removal, and beveling on mild and carbon steels. It is engineered to perform in both manual and robotic grinding operations. The closed-coat construction and 36 plus grit rating make it appropriate for aggressive initial cuts where surface finish is secondary to material removal rate. Fabricators, welders, and metal finishing professionals are the primary users. The design reduces metal discoloration and lowers the risk of stress cracks on mild or carbon steels, which matters in precision fabrication environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eRe-Engineered Precision Shaped Grain continuously fractures to maintain sharp cutting points throughout disc life\u003c\/li\u003e\n\u003cli\u003eDelivers up to 51 percent faster initial cut rate and up to 61 percent faster sustained cut rate compared to the Cubitron II Fibre Disc 982C at 36 plus grit\u003c\/li\u003e\n\u003cli\u003eStiff fiber backing and strong resin bond resist tearing under medium to high grinding pressure\u003c\/li\u003e\n\u003cli\u003eCompatible with robotic grinding operations in addition to manual use\u003c\/li\u003e\n\u003cli\u003eReduces operator pressure required, helping minimize metal discoloration and stress cracking on mild or carbon steels\u003c\/li\u003e\n\u003cli\u003eClosed-coat construction maximizes abrasive mineral coverage for consistent stock removal\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and upgrade path from the Cubitron II Fibre Disc 982C 36 plus grit.

Always power down and disconnect the grinder before mounting or removing a disc. Inspect the backing pad for damage before installation, and confirm the grinder RPM rating meets or exceeds the disc RPM rating. Wear appropriate PPE including face shield and gloves during operation and disc changes.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 36 plus\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoat Type\u003c\/strong\u003e: Closed Coat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Technology\u003c\/strong\u003e: Re-Engineered Precision Shaped Grain\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacking\u003c\/strong\u003e: Stiff Fiber\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.367 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Box\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00068060664532\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: 7100309906\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51344427581746,"sku":"7100309906","price":834.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310535597.jpg?v=1782035740","url":"https:\/\/voomisupply.com\/products\/3m-7100309906-cubitron-3-fiber-disc-36-grit-7-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
