Coated with TiAlN via a PVD process, the IC807 grade delivers wear resistance and thermal stability across a range of workpiece materials. The insert features a 0.5-inch inscribed circle, a 3\/16-inch thickness, and a 1\/32-inch corner radius, making it suitable for medium to semi-finishing cuts. It is installed by licensed machinists and CNC operators working with ferrous and non-ferrous alloys.\u003c\/p\u003e\u003cp\u003eThis insert is intended for machining primary workpiece material categories M, P, and S, corresponding to stainless steels, carbon and alloy steels, and superalloys. The TF chip breaker geometry promotes positive rake cutting action, supporting controlled chip formation during turning. Typical applications include shaft turning, facing, and profiling operations in production and job-shop environments. The clamp and pin holding method ensures secure seating in compatible SNMG toolholders.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eIC807 submicron solid carbide grade with TiAlN PVD coating for extended tool life\u003c\/li\u003e\n\u003cli\u003eSNMG432 insert style with 90-degree square shape and positive rake geometry\u003c\/li\u003e\n\u003cli\u003eTF chip breaker for controlled chip evacuation during medium-to-finish turning\u003c\/li\u003e\n\u003cli\u003e0.5-inch inscribed circle and 3\/16-inch thickness for rigid, stable seating\u003c\/li\u003e\n\u003cli\u003e1\/32-inch corner radius balances edge strength and surface finish quality\u003c\/li\u003e\n\u003cli\u003eClamp and pin holding method for secure insert retention in SNMG toolholders\u003c\/li\u003e\n\u003cli\u003eConforms to ISO 13399 cutting tool data standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard production insert for SNMG-style toolholders accepting 432-size inserts with clamp and pin retention.

Use a torx or hex key of the correct size as specified by the toolholder manufacturer to seat the clamp securely. Inspect the toolholder pocket and seating surfaces for debris or wear before inserting. Verify insert orientation matches the required chip breaker direction for the programmed toolpath before resuming cutting operations.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: SNMG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: SNMG432\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: IC807\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: Submicron\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 Shape\u003c\/strong\u003e: Square (90 degrees)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: TF\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 Thickness\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.5 inches (12.70 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0313 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\u003eClearance Code\u003c\/strong\u003e: N\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\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: M, P, S (Stainless Steel, Carbon and Alloy Steel, Superalloys)\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: 0.227 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: 5508239\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51731738132786,"sku":"5508239","price":211.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1ea73ad13610f2268025d0adf7c6e4c8.jpg?v=1788734389","url":"https:\/\/voomisupply.com\/products\/iscar-5508239-snmg432tf-ic807-turning-insert-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
