The 80-degree diamond shape (C-style) provides a strong, rigid cutting geometry suited to interrupted and continuous turning operations. With a 0.5-inch inscribed circle, a 0.1875-inch insert thickness, and a 1\/64-inch (0.0157-inch) corner radius, this insert is built for general turning where edge stability and coating wear resistance are the primary performance requirements. The IC9250 grade targets medium to finishing cuts on stainless steel and carbon steel. A licensed machinist or CNC turning specialist installs and indexes this insert.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for turning centers and engine lathes running ISO-designated workpiece material groups M (stainless steel) and P (carbon and alloy steel). The PP chip breaker geometry produces a positive rake angle suited to lighter depths of cut and finishing passes where chip control on gummy or work-hardening materials is critical. Maximum depth of cut is 4.00 mm (0.1575 inches). The Isoturn series is a standard ISCAR product family for external and internal turning applications in production and job-shop environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCNMG 431-PP geometry with 80-degree diamond shape and positive rake for controlled chip flow on stainless and steel\u003c\/li\u003e\n  \u003cli\u003eCVD multilayer coating: TiCN base, Al2O3 thermal barrier, TiN topcoat for wear resistance and heat management\u003c\/li\u003e\n  \u003cli\u003eIC9250 carbide grade optimized for ISO material groups M and P\u003c\/li\u003e\n  \u003cli\u003eCorner radius of 1\/64 inch (0.0157 inch) for finishing and semi-finishing surface quality\u003c\/li\u003e\n  \u003cli\u003eCompatible with clamp and pin insert-holding methods\u003c\/li\u003e\n  \u003cli\u003eConforms to ISO 13399 cutting tool data representation standard\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNMG-style insert pockets accepting a 431 insert size with clamp or pin holding.

Ensure the insert pocket and seating surfaces are clean and free of chips before seating the insert. Use the appropriate torque wrench and clamp screw specified by the toolholder manufacturer — do not overtighten, as carbide inserts are brittle and can crack under excessive clamping force. Inspect the insert edge condition at each tool change and do not run a visibly worn or chipped edge.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: CNMG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond (80 degrees)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: PP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: IC9250\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, Al2O3, TiN (CVD process)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 12.90 mm (0.5079 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3\/16 inch (0.1874 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inch (0.0157 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 4.00 mm (0.1575 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, Pin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel, Steel (ISO Groups M, P)\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\u003ePackage Weight\u003c\/strong\u003e: 1 pound\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: 5507321\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51749503533362,"sku":"5507321","price":221.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bbf37d1a12ac6f457a7ab3ed956b0fad.jpg?v=1788906927","url":"https:\/\/voomisupply.com\/products\/iscar-5507321-turning-insert-cnmg-431-pp-ic9250-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
