The insert is manufactured from solid carbide and features a CVD-applied Duratomic multilayer coating of TiCN, Al2O3, and Cr. It has a diamond 80-degree included angle, a 0.5-inch inscribed circle, a 1\/32-inch corner radius, and a negative rake geometry with a chamfered and honed cutting edge. With four usable cutting edges and an MF4 chip breaker, it is suited for finish to medium turning operations where consistent chip control on difficult materials is required. Licensed machinists and CNC operators are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis insert is engineered primarily for stainless steel (ISO material group M, grades M15, M20, M25) and is also rated for general steel (ISO group P). Typical applications include exterior turning, facing, and boring operations on a lathe or turning center. The MF4 chip breaker geometry is optimized for moderate feed rates and depths of cut up to 0.4756 inches, making it well suited for production turning of stainless components such as fittings, shafts, and flanges found in HVAC, plumbing, and industrial supply chains.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCVD Duratomic coating (TiCN, Al2O3, Cr) for extended tool life on stainless and steel\u003c\/li\u003e\n  \u003cli\u003eMF4 chip breaker for controlled chip evacuation at moderate feeds\u003c\/li\u003e\n  \u003cli\u003eFour cutting edges per insert for maximum value per unit\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond insert shape (code C) with negative rake for rigidity\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 standards; ISO code CNMG120408-MF4\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct replacement for CNMG432-MF4 geometry toolholders using clamp, pin, or lever-lock insert seating methods conforming to ANSI and ISO CNMG seating standards.

Before indexing or replacing the insert, power down the machine, engage the spindle lock, and relieve any coolant pressure. Use the correct torque wrench and manufacturer-specified seating screw when securing the insert in the pocket to ensure proper contact with the locating surfaces. Inspect the insert pocket for chips or debris before seating the new cutting edge.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndustry Standard Number\u003c\/strong\u003e: CNMG432-MF4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: CNMG120408-MF4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: TM1501\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: Diamond 80 degrees (Code C)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 80 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0315 inches (1\/32 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1874 inches (3\/16 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.5079 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2028 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.4756 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: MF4\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: 30 degrees\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 Hand\u003c\/strong\u003e: Neutral\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: M\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: Stainless Steel (ISO Group M)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Steel (ISO Group P)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M15, M20, M25\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplications\u003c\/strong\u003e: Boring, Facing, Turning\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 insert per package\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 0.39 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 3.54 inches\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: 03273903\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51558300483890,"sku":"03273903","price":255.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e0cfc51d89bcc554843b6eb4d95433b4_4e3f480a-d555-4733-966a-3e91a6d91fba.jpg?v=1786408964","url":"https:\/\/voomisupply.com\/products\/seco-03273903-turning-insert-cnmg432-mf4-tm1501-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
