The insert carries ANSI designation TPU 321 IC9054 and ISO code TPUN 160304. It features a triangular shape with a 60-degree included angle, three cutting edges, and a positive rake geometry with an 11-degree relief angle. The IC9054 grade is produced via CVD coating, applying a TiCN, Al2O3, and TiN multilayer stack to the solid carbide substrate. The corner radius measures 0.0157 inches (0.40 mm), and the inscribed circle diameter is 0.3748 inches. The insert is single-sided with a flat-top chip breaker and is held in place by a clamp-style toolholder.\u003c\/p\u003e\u003cp\u003eThis insert is suited for face milling, shoulder milling, and general-purpose milling of steel and stainless steel workpieces in both roughing and semi-finishing operations. The IC9054 CVD grade is optimized for P and M material classifications per ISO designation, covering carbon steels, alloy steels, and austenitic stainless steels. It fits ISCARMILL-series milling bodies that accept TPU 321 style inserts. The neutral hand orientation allows use across a wide range of compatible toolholders. Maximum depth of cut reaches 0.6142 inches, making it appropriate for moderate material removal rates in production milling environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTriangular insert shape with 60-degree included angle and three usable cutting edges\u003c\/li\u003e\n\u003cli\u003eIC9054 grade with CVD-applied TiCN, Al2O3, and TiN multilayer coating for wear resistance on steel and stainless steel\u003c\/li\u003e\n\u003cli\u003ePositive rake geometry with 11-degree relief angle reduces cutting forces on the workpiece\u003c\/li\u003e\n\u003cli\u003eFlat-top chip breaker with honed cutting edge style for stable chip control\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.0157 inches (1\/64 inch) for light finishing passes or general-purpose milling\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut and effective cutting edge length of 0.6142 inches\u003c\/li\u003e\n\u003cli\u003eClamp-style insert holding compatible with standard ISCARMILL toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement insert for ISCARMILL-series milling toolholders that accept TPU 321 style clamp-held inserts with an inscribed circle of 3\/8 inch and 1\/8 inch thickness.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInsert replacement should be performed by a qualified machinist or tooling technician with the spindle locked and machine power isolated. Use the appropriate torque wrench and clamping hardware specified by the toolholder manufacturer when seating the insert. Inspect the toolholder pocket and clamp for wear or damage before installing a new insert. Ensure the seating surface is clean and free of chips to prevent insert rocking and premature edge failure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: TPU\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Triangle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 321\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: TPU 321 IC9054\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: TPUN 160304\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: IC9054\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Layers\u003c\/strong\u003e: TiCN, Al2O3, TiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\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: 11 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: Flat Top\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Honed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double Sided\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0157 inches (0.40 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle Diameter\u003c\/strong\u003e: 0.3748 inches (3\/8 inch nominal)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1250 inches (1\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.6299 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.6299 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.6142 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge Effective Length\u003c\/strong\u003e: 0.6142 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel (ISO P, M)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: ISCARMILL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO 13399\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.121 pounds\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\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: 5507596\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51732353548594,"sku":"5507596","price":171.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ece0ce2f1417e8ed2fd4a0fe146a8505.jpg?v=1788741969","url":"https:\/\/voomisupply.com\/products\/iscar-5507596-tpu-321-ic9054-triangle-milling-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
