It features an 80-degree trigon (W-shape) insert profile with a positive rake angle and a neutral 0-degree relief angle (clearance code N, tolerance code M). The inscribed circle measures 0.5000 inches and the corner radius is 0.0315 inches (1\/32 inch). Insert length is 8.70 mm (0.3425 inches) and insert thickness is 0.1874 inches. The TF chip breaker geometry is designed for light-to-medium turning operations across a broad range of workpiece materials. Holding method is clamp and pin. This insert is sold individually with a minimum order quantity of 10.\u003c\/p\u003e\u003cp\u003eThe WNMG 432-TF IC20 insert is rated for universal primary workpiece material compatibility, covering ISO material groups H, K, M, N, and S. It is suited for external turning applications on CNC lathes and turning centers where a positive-rake insert with controlled chip breaking is required. The IC20 substrate grade corresponds to material grades C2 and C3, making it applicable across cast iron, non-ferrous, stainless, and heat-resistant alloy turning at appropriate cutting parameters. It is a standard replacement insert for Isoturn toolholders that accept WNMG 432 geometry inserts.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWNMG 432-TF geometry with positive rake for reduced cutting forces\u003c\/li\u003e\n\u003cli\u003e80-degree trigon insert shape (W) with 0.0315-inch corner radius\u003c\/li\u003e\n\u003cli\u003eSolid carbide IC20 substrate, uncoated — no coating degradation at regrind\u003c\/li\u003e\n\u003cli\u003eTF chip breaker for light-to-medium turning across multiple material groups\u003c\/li\u003e\n\u003cli\u003eCompatible with clamp-and-pin style WNMG toolholders\u003c\/li\u003e\n\u003cli\u003eConforms to ISO 13399 standards for insert identification and tooling data\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement insert for Isoturn series toolholders accepting WNMG 432 insert geometry with clamp-and-pin holding.

Power down and lock out the machine before indexing or replacing inserts. Use the correct torque tool for the clamping screw to avoid insert or pocket damage — refer to the toolholder manufacturer specifications for torque values. Inspect the insert seat and chip pocket for debris before seating a new insert.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: WNMG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Trigon (W), 80-degree included angle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: TF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: IC20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2, C3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5000 inches (1\/2 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0315 inches (1\/32 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 8.70 mm (0.3425 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1874 inches (3\/16 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2030 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.1570 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees (Clearance Code N)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp and Pin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Universal (H, K, M, N, S)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Isoturn\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ISO 13399\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 (minimum order quantity: 10)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ISCAR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5503798\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51731242615090,"sku":"5503798","price":177.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9428d91f2bbeafb874fad42ad5cb3a95.jpg?v=1788728761","url":"https:\/\/voomisupply.com\/products\/iscar-5503798-wnmg-432-tf-ic20-turning-insert-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
