This triangular insert carries the industry-standard designation TNMA432 and is manufactured to the TK0501 grade with a CVD-applied Duratomic coating of TiCN, Al2O3, and Cr layers. The coating improves wear resistance and thermal stability during interrupted and continuous cuts. With a 0.5-inch inscribed circle, a 0.0315-inch corner radius, a neutral hand orientation, and six available cutting edges, this insert delivers consistent tool life across roughing and finishing passes. It conforms to both ANSI and ISO standards.\u003c\/p\u003e\n\u003cp\u003eThis insert is rated primarily for cast iron and secondarily for hard materials, making it a practical choice for machining gray iron, ductile iron, and similar ferrous workpieces. Its flat-top chip breaker geometry and chamfered-and-honed cutting edge style suit operations including turning, facing, boring, and back turning. The negative rake angle and zero-degree clearance are typical of mechanically clamped insert tooling used in production environments where rigidity and edge security are priorities. It is sold individually but requires a minimum order of five pieces per transaction.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCVD Duratomic coating: TiCN, Al2O3, and Cr layers for extended wear resistance in cast iron applications\u003c\/li\u003e\n  \u003cli\u003eSix cutting edges per insert for cost-effective tool management\u003c\/li\u003e\n  \u003cli\u003eFlat-top chip breaker geometry supports turning, facing, boring, and back turning\u003c\/li\u003e\n  \u003cli\u003eChamfered and honed cutting edge style for stable entry and reduced chipping risk\u003c\/li\u003e\n  \u003cli\u003eNeutral hand orientation — compatible with both right-hand and left-hand toolholders\u003c\/li\u003e\n  \u003cli\u003eCompatible with clamp, pin, and lever-lock insert holding methods\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI and ISO insert standards; ISO code TNMA220408\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in TNMA-series toolholders that accept a 0.5-inch inscribed circle triangular insert with a 0.2028-inch hole diameter.

Before indexing or replacing an insert, shut down the spindle completely and allow the cutting zone to cool. Use the appropriate torque wrench and manufacturer-specified clamp hardware for the toolholder style in use — do not substitute fasteners. Inspect the toolholder pocket and seating surfaces for debris or wear before seating the new insert, as pocket condition directly affects edge runout and tool life.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndustry Standard Number\u003c\/strong\u003e: TNMA432\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: TNMA220408\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Series\u003c\/strong\u003e: TNMA Flat Top\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: TK0501\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: K05; K10; K15\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, Al2O3, Cr (CVD Duratomic)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Triangle (60 degrees included angle)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 22 mm (0.8661 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1874 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0315 inches (1\/32 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2028 inches (5.15 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.8346 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 6\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: Negative\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 0 degrees\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\u003eChip Breaker\u003c\/strong\u003e: Flat Top\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Chamfered and Honed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp, Pin, Lever Lock\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron (K)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Hard Material (H)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMulti-Use Application\u003c\/strong\u003e: Back Turning, Boring, Facing, Turning\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 pounds\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: SECO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 03064398\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51559759085874,"sku":"03064398","price":157.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/581c7a81203fc91783d975fb91070716.jpg?v=1786440184","url":"https:\/\/voomisupply.com\/products\/seco-03064398-turning-insert-tnma432-tk0501-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
