Designated ANSI insert code RD12 and ISO insert code RD12, this insert features a round shape (style R) with a 3\/4 inch inscribed circle and a 0.1875 inch thickness. The Manufacturer Grade I22 carbide substrate is uncoated (bright finish), offering a sharp, low-friction cutting edge suited for finishing and semi-finishing passes. Screw-clamped holding method provides rigid, repeatable seating in compatible toolholders. The positive side clearance geometry reduces cutting forces and supports clean chip evacuation on a range of workpiece materials.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for turning operations on cast iron, stainless steel, non-ferrous metals, and high-temperature alloys, corresponding to primary workpiece material codes K, M, N, and S. It is suited for use in production machine shops, aerospace component work, and general-purpose turning where an uncoated carbide insert with a round profile is required. Each package contains one insert, with a minimum order quantity of 10 units. Licensed machinists and CNC operators are the primary installers and end users of this tooling item.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRound insert shape (style R) with 3\/4 inch inscribed circle for full 360-degree edge utilization\u003c\/li\u003e\n  \u003cli\u003eSolid carbide substrate, Material Grade C2, uncoated bright finish for sharp edge retention\u003c\/li\u003e\n  \u003cli\u003eManufacturer Grade I22 for consistent performance across compatible workpiece materials\u003c\/li\u003e\n  \u003cli\u003ePositive side clearance geometry reduces cutting forces and supports chip flow\u003c\/li\u003e\n  \u003cli\u003eScrew-clamped holding method ensures secure, repeatable insert positioning\u003c\/li\u003e\n  \u003cli\u003eCompatible with primary workpiece material codes K, M, N, and S\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement for ANSI RD12 and ISO RD12 round turning insert seats in compatible screw-clamp toolholders accepting a 3\/4 inch inscribed circle, 0.1875 inch thick insert with a 0.2000 inch hole diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of turning inserts should be performed by a qualified machinist with the machine fully powered down and the spindle locked before indexing or replacing the insert. Use the appropriate Torx or hex key to tighten the clamping screw to the toolholder manufacturer's specified torque — do not overtighten, as this can fracture the carbide. Inspect the insert pocket and clamping components for debris or wear before seating a new insert. Confirm correct insert orientation and seating before resuming cutting operations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: RD12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: RD12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: RD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: R - Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/4 inch (0.7500 inches \/ 19.05 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: I22\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating \/ Finish\u003c\/strong\u003e: Bright \/ Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 6 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material Codes\u003c\/strong\u003e: K, M, N, S\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Size Code\u003c\/strong\u003e: 12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Size Code\u003c\/strong\u003e: 12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0016 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: ICR39430E\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51693356089650,"sku":"ICR39430E","price":433.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/152daa48a636bc4749ec07aa1b3e7fbe.jpg?v=1788311154","url":"https:\/\/voomisupply.com\/products\/value-collection-icr39430e-round-turning-insert-carbide-i22","provider":"Voomi Supply","version":"1.0","type":"link"}
