Manufactured to the CNGA431T geometry with an 80-degree diamond (rhombic) shape and a negative side clearance, this insert is engineered for rigidity and dimensional consistency. It carries the IN22 manufacturer grade, which is optimized for high wear resistance in cast iron (K) applications and moderate wear resistance with toughness in hardened materials (H). The insert conforms to ISO 13399 standards and fits securely using a clamp and pin holding method. It is sold individually with a minimum order quantity of 10 pieces.\u003c\/p\u003e\u003cp\u003eThis insert is suited for finishing operations on cast iron components and hardened workpieces in both production and job-shop environments. The CNGA431T geometry, combined with the uncoated ceramic substrate, supports high cutting speeds where coolant-free or dry-cutting conditions are preferred. Machinists and CNC turning specialists working with brake rotors, pump housings, cylinder liners, and similar cast iron or hardened-steel parts will find this insert appropriate for light, precise finishing passes. It is compatible with toolholders designed for CNGA-style inserts with a negative rake configuration.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eUncoated ceramic substrate delivers high wear resistance at elevated cutting speeds\u003c\/li\u003e\n\u003cli\u003e80-degree diamond insert shape provides a strong cutting edge with good chip clearance geometry\u003c\/li\u003e\n\u003cli\u003eIN22 grade rated for cast iron (K) and hardened materials (H) applications\u003c\/li\u003e\n\u003cli\u003eChip breaker style T optimized for finishing operations with a maximum depth of cut of 0.0157 inches (0.40 mm)\u003c\/li\u003e\n\u003cli\u003eNegative side clearance and CNGA geometry for use in rigid, clamp-and-pin toolholding systems\u003c\/li\u003e\n\u003cli\u003eConforms to ISO 13399 standard for seamless tool data integration\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNGA-style turning toolholders with clamp and pin holding method accepting a negative rake insert.

Power down and lock out the machine spindle before changing or indexing inserts. Inspect the toolholder pocket and seating surface for debris or damage before seating the insert, as ceramic inserts are brittle and sensitive to interrupted cuts or improper clamping. Do not use this insert on interrupted cuts or in conditions that exceed the rated maximum depth of cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: CNGA431\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: CNGA120404\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: IN22\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Ceramic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inches (0.0157 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 inches (0.1874 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: 0.40 mm (0.0157 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Negative\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: T (Finishing)\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: Cast Iron, Hardened Materials\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Isoturn\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C3, C4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\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: 5791848\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51741609787698,"sku":"5791848","price":222.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/90958cb0c74c8b333aae2b68bd78e081.jpg?v=1788832463","url":"https:\/\/voomisupply.com\/products\/iscar-5791848-ceramic-turning-insert-80-deg-diamond","provider":"Voomi Supply","version":"1.0","type":"link"}
