It features a 60-degree triangular insert shape with an 11-degree relief angle and a 3\/8-inch inscribed circle. The corner radius measures 1\/64 inch (0.016 inch), and the insert thickness is 1\/8 inch. Designed for precision turning operations, this insert uses screw-style holding and conforms to ISO 13399 standards. It is suited for machinists and CNC operators performing external turning on a range of workpiece materials across general machining environments.\u003c\/p\u003e\n\u003cp\u003eThis insert is rated for universal primary workpiece material compatibility, covering ISO material groups H, K, M, N, and S. Typical applications include external turning on lathes and turning centers in job shop, production, and maintenance machining settings. The Isoturn series is designed for consistent performance in light to moderate material removal, with a maximum depth of cut of 0.157 inch (3.99 mm). The IC20 grade is an uncoated solid carbide, making it well suited for applications where coated grades may not be preferred, such as certain non-ferrous or specialty material cuts.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTPMT 321 insert geometry with 60-degree triangular shape and 11-degree relief angle\u003c\/li\u003e\n  \u003cli\u003eIC20 uncoated solid carbide grade for broad material compatibility\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch inscribed circle with 1\/64-inch corner radius for precision finish\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut of 0.157 inch (3.99 mm)\u003c\/li\u003e\n  \u003cli\u003eScrew-style insert holding method for secure seating in compatible toolholders\u003c\/li\u003e\n  \u003cli\u003eConforms to ISO 13399 standards for insert identification and interoperability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement turning insert for TPMT-style toolholders compatible with the TPMT 321 insert size code.

Before replacing an insert, ensure the machine is powered down and the spindle is fully stopped. Use the appropriate torx or hex key to loosen the clamping screw, seat the insert fully into the toolholder pocket, and torque the screw according to the toolholder manufacturer specifications. Inspect the insert seat and chip breaker pocket for debris before installing a new insert.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: TPMT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: TPMT 321\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Triangle (60 degrees)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: IC20\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 (0.375 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.65 inch (16.51 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 1\/8 inch (0.125 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inch (0.016 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 11 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.169 inch (4.29 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.157 inch (3.99 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Universal (H, K, M, N, S)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Isoturn\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO 13399\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\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: 5502201\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51749678874930,"sku":"5502201","price":203.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/78cea73cb6d499850d71b7621e6a4331.jpg?v=1788909119","url":"https:\/\/voomisupply.com\/products\/iscar-5502201-turning-insert-tpmt-321-ic20-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
