It features a CVD-applied TiCN and Al2O3 multilayer coating that improves wear resistance and thermal stability during continuous and interrupted cuts. The triangular insert shape (60-degree included angle) provides three usable cutting edges. With a 0.375-inch inscribed circle, a 0.125-inch insert thickness, and a 0.016-inch corner radius, this insert is suited to medium-duty turning passes where tight tolerances and good surface finish are required. It is installed and managed by machinists and CNC tooling specialists.\u003c\/p\u003e\u003cp\u003eThis insert is intended for turning stainless steel and carbon or alloy steel workpieces, corresponding to ISO material groups M and P. The TF chip breaker geometry is optimized for positive-rake cutting action, which reduces cutting forces and helps manage chip flow on ductile materials. Typical applications include external turning, facing, and light profiling on production turning equipment. It fits into standard TNMG-style toolholders that accept clamp-and-pin insert holding. The Isoturn series designation confirms compatibility with ISCAR Isoturn toolholder systems. Maximum depth of cut is 3.00 mm (0.118 inches).\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eIC9250 grade with CVD TiCN and Al2O3 coating for wear and thermal resistance\u003c\/li\u003e\n\u003cli\u003ePositive-rake TF chip breaker geometry reduces cutting forces on steel and stainless\u003c\/li\u003e\n\u003cli\u003eThree usable cutting edges on a 60-degree triangular insert body\u003c\/li\u003e\n\u003cli\u003e0.016-inch corner radius suitable for medium-finish turning passes\u003c\/li\u003e\n\u003cli\u003eClamp and pin holding method for secure seating in compatible toolholders\u003c\/li\u003e\n\u003cli\u003eCompliant with ISO 13399 cutting tool data standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in TNMG-style toolholders that accept clamp-and-pin insert retention.

Use the appropriate torque wrench and clamp hardware specified by the toolholder manufacturer when seating the insert. Inspect the insert pocket and seating surface for chips or debris before installing a new edge. Never rotate or flip the insert while the toolholder is under load or while the machine is running.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: TNMG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: TNMG 321-TF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Isoturn\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: IC9250\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN and Al2O3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Triangle (T)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 16.51 mm (0.650 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.016 inches (1\/64 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 3.00 mm (0.118 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: TF\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\u003eInsert Holding Method\u003c\/strong\u003e: Clamp and Pin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel and Steel (ISO M and P)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\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\u003eWeight\u003c\/strong\u003e: 1 pound\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: 5507566\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51731466846514,"sku":"5507566","price":137.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/551a7043bfe0eee022e26881d2d0be7c.jpg?v=1788731456","url":"https:\/\/voomisupply.com\/products\/iscar-5507566-tnmg-321-tf-ic9250-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
