It features an 80-degree diamond shape with a positive rake angle and a TF chip breaker design. The insert is uncoated (bright finish) with a 0.5-inch inscribed circle, a 0.016-inch corner radius, and an insert length of 12.90 mm (0.508 inches). It carries a clearance code of N and tolerance code of M. Licensed machinists and CNC lathe operators install this insert in clamp-and-pin style toolholders for turning and boring operations across a wide range of workpiece materials.\u003c\/p\u003e\n\u003cp\u003eThis insert is rated for universal primary workpiece material compatibility, covering ISO material groups H, K, M, N, P, and S. Typical applications include external turning, internal boring, and general-purpose lathe work on ferrous metals, non-ferrous alloys, heat-resistant superalloys, and hardened materials. The TF chip breaker geometry supports consistent chip control across light to moderate depths of cut, with a maximum depth of cut of 3.99 mm (0.157 inches). It is suited for both roughing passes at shallower depths and finishing operations where edge consistency matters.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCNMG 431-TF geometry with 80-degree diamond insert shape for strong cutting edge\u003c\/li\u003e\n  \u003cli\u003eUncoated solid carbide grade IC20 — no coating delamination risk in demanding cuts\u003c\/li\u003e\n  \u003cli\u003eTF chip breaker for reliable chip control across multiple material groups\u003c\/li\u003e\n  \u003cli\u003ePositive rake angle reduces cutting forces and heat generation at the edge\u003c\/li\u003e\n  \u003cli\u003eClamp and pin holding method provides rigid, repeatable insert indexing\u003c\/li\u003e\n  \u003cli\u003eMulti-use tool rated for both turning and boring applications\u003c\/li\u003e\n  \u003cli\u003eConforms to ISO 13399 insert identification standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNMG-style clamp-and-pin toolholders that accept a 0.5-inch inscribed circle, 3\/16-inch thick diamond insert.

Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate torque wrench and clamp hardware specified by the toolholder manufacturer — do not substitute fasteners. Inspect the insert seat for chips or debris before seating a new insert to ensure proper contact and edge alignment.\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\u003eISO Code\u003c\/strong\u003e: CNMG 431-TF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Isoturn\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond (80 degrees)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape Code\u003c\/strong\u003e: C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: IC20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inch (0.0160 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 12.90 mm (0.508 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3\/16 inch (0.1870 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 3.99 mm (0.157 inches)\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: 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\u003eChip Breaker\u003c\/strong\u003e: TF\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, P, S)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMulti-Use Application\u003c\/strong\u003e: Turning and Boring\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: 5503801\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51730459787570,"sku":"5503801","price":175.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6e627615b9304576f222fb218a35bb35.jpg?v=1788717818","url":"https:\/\/voomisupply.com\/products\/iscar-5503801-turning-insert-cnmg-431-tf-ic20-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
