It features a PVD-applied TiAlN coating over a carbide substrate, targeting high wear-resistance across steel, stainless steel, and cast iron workpiece materials. The insert carries an 80-degree diamond (rhombic) shape with a negative side clearance and a 0.0157-inch corner radius. At 12.9 mm in length with a 0.5-inch inscribed circle and 0.1874-inch thickness, this insert is sized for general turning operations ranging from roughing to medium machining in CNC and manual turning applications.\u003c\/p\u003e\u003cp\u003eThis insert is designed for use in external and internal turning operations on steel (ISO P), stainless steel (ISO M), cast iron (ISO K), and superalloy (ISO S) workpiece materials. The PP chip breaker geometry supports roughing and medium machining passes, making it well suited for production turning where consistent chip control and tool life are priorities. It is typically installed in indexable toolholders by machinists and CNC operators in job shops, OEM machining centers, and maintenance-repair machine shops.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePVD TiAlN coating provides high wear-resistance with retained toughness across P, M, K, and S material codes\u003c\/li\u003e\n\u003cli\u003e80-degree diamond insert shape (CNMG) allows two usable cutting edges per insert\u003c\/li\u003e\n\u003cli\u003ePP chip breaker geometry engineered for roughing and medium machining operations\u003c\/li\u003e\n\u003cli\u003eNegative side clearance with positive rake for stable, aggressive cutting action\u003c\/li\u003e\n\u003cli\u003eIC807 manufacturer grade suitable for steel, stainless steel, cast iron, and superalloys\u003c\/li\u003e\n\u003cli\u003eCompliant with ISO 13399 tooling data standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style indexable turning insert for use in CNMG-style toolholders accepting a 431 (ISO 120404) insert size with clamp or pin holding methods, as specified by the ANSI and ISO insert codes.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists or CNC setup technicians. The machine spindle must be fully stopped and the toolholder secured in the turret before indexing or replacing the insert. Use the appropriate torque wrench and manufacturer-specified clamp hardware for the toolholder to seat the insert correctly. Do not exceed the maximum depth of cut of 0.1575 inches per the insert geometry limits.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: CNMG431\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: CNMG120404\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: C - Diamond (Rhombic) 80 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: IC807\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Isoturn\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: PP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker Operation\u003c\/strong\u003e: Roughing, Medium Machining\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: 12.9 mm (0.5079 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1874 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0157 inches (1\/64 inches)\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: 0.1575 inches (4.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Negative\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 Materials\u003c\/strong\u003e: Steel (P), Stainless Steel (M), Cast Iron (K), Superalloys (S)\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\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: 5507873\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51744551862578,"sku":"5507873","price":220.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/892ec01ffde794429073b33902972c7b.jpg?v=1788858020","url":"https:\/\/voomisupply.com\/products\/iscar-5507873-turning-insert-cnmg431pp-ic807-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
