Manufactured under the Isoturn series, this triangular insert features an IN23 ceramic grade and an uncoated surface. It carries a 3\/8 inch inscribed circle, a 0.0315 inch corner radius, and a 60-degree included angle. The insert measures 16.5 mm (0.6496 inches) in length and 0.1874 inches in thickness. It is held in place using a clamp and pin method. Licensed machinists and CNC operators install this insert when finishing or semi-finishing hard or abrasive workpiece materials at elevated cutting speeds.\u003c\/p\u003e\u003cp\u003eThis insert is suited for turning applications on cast iron and hard materials, corresponding to workpiece material codes H and K per ISO 13399. The Isoturn series targets high-speed, high-temperature cutting conditions where ceramic tooling outperforms carbide. Maximum depth of cut is 3.5 mm (0.1378 inches). Typical applications include finish turning of gray cast iron components, hardened steel parts, and similar abrasive workpieces in production machining environments. The TNGA geometry with a zero-degree relief angle (clearance code N, tolerance code G) is well suited to rigid tooling setups where insert seating accuracy is critical.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eIN23 ceramic grade, uncoated, optimized for hard and cast iron workpiece materials\u003c\/li\u003e\n\u003cli\u003eTriangular insert shape (60-degree included angle) with TNGA style geometry\u003c\/li\u003e\n\u003cli\u003e3\/8 inch inscribed circle with 0.0315 inch corner radius for controlled edge engagement\u003c\/li\u003e\n\u003cli\u003eClamp and pin holding method for secure, repeatable insert positioning\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut of 3.5 mm (0.1378 inches) for semi-finish and finish passes\u003c\/li\u003e\n\u003cli\u003eConforms to ISO 13399 tooling data standards for compatibility with CAM and tool management systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement ceramic turning insert for TNGA-format toolholders in the Isoturn series.

Always power down and lock out the machine before changing inserts. Ensure the insert pocket and clamping surfaces are clean and free of chips before seating the insert. Clamp and pin retention systems require that the pin bore and clamp finger are inspected for wear at each insert change to maintain proper seating and prevent insert movement during cutting.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: TNGA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Triangle (60 degrees)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Ceramic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: IN23\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inch (0.3748 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/32 inch (0.0315 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 16.5 mm (0.6496 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\u003eMaximum Depth of Cut\u003c\/strong\u003e: 3.5 mm (0.1378 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: G\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\u003eChip Breaker\u003c\/strong\u003e: T\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 332\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Hard Material (Codes H, K)\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: 0.03 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: 5700399\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51753224667442,"sku":"5700399","price":198.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0b6ed217640cd5d6e5cd6b85898f4943.jpg?v=1788934081","url":"https:\/\/voomisupply.com\/products\/iscar-5700399-tnga-332t-in23-ceramic-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
