This insert carries the SCMT431-14 designation and is manufactured to the IC8250 grade, featuring a CVD-applied TiCN plus Al2O3 multilayer coating for wear resistance and thermal stability at elevated cutting speeds. The square insert shape with a 90-degree included angle and a positive rake geometry provides efficient chip control across a range of steel and stainless steel workpiece materials. It fits the Isoturn series tooling system and is secured by screw clamping. The 0.0157 inch corner radius suits general-purpose finishing and medium turning passes.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for turning operations in both production and job-shop environments. The IC8250 grade with its CVD TiCN and Al2O3 coating is engineered primarily for machining ISO P workpiece materials (steels) with secondary suitability for ISO M materials (stainless steels). Typical applications include shaft turning, facing, and profiling on CNC turning centers where consistent tool life and surface finish are priorities. It is installed in compatible SCMT-style insert pockets within the Isoturn tooling system.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eIC8250 grade with CVD TiCN plus Al2O3 multilayer coating for extended tool life in steel cutting\u003c\/li\u003e\n  \u003cli\u003eSquare insert shape with 90-degree included angle and positive rake for efficient chip formation\u003c\/li\u003e\n  \u003cli\u003e0.0157 inch (1\/64 inch) corner radius suitable for general-purpose medium turning and finishing\u003c\/li\u003e\n  \u003cli\u003eScrew-clamping insert holding method for secure seating and repeatable indexing\u003c\/li\u003e\n  \u003cli\u003eIsoturn series compatibility with ISO 13399 standardized geometry coding\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut of 0.1575 inch (4.00 mm) for medium material removal applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in SCMT-style insert pockets within the ISCAR Isoturn series tooling system.

Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate torx or hex key to torque the clamping screw to the toolholder manufacturer's specified value. Inspect the insert pocket seat and shim for damage or debris before seating the new insert, as a contaminated pocket can cause premature insert failure or poor surface finish.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: SCMT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Isoturn\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: IC8250\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: TiCN plus Al2O3 (CVD Process)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Square (S)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 7 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5000 inch (1\/2 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1874 inch (3\/16 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.5000 inch (12.70 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0157 inch (1\/64 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2165 inch (5.50 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.1575 inch (4.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: 14\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\u003c\/strong\u003e: ISO P (Steels)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: ISO M (Stainless Steels)\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: 0.05 pounds\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: ISCAR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5550405\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51738660929842,"sku":"5550405","price":301.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5163b9f23a75ff2d1d68867eadf13cef.jpg?v=1788802445","url":"https:\/\/voomisupply.com\/products\/iscar-5550405-turning-insert-scmt431-14-ic8250-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
