The insert is manufactured from solid carbide and coated via CVD with a multilayer TiCN, Al2O3, and Cr Duratomic coating designed to extend tool life and maintain edge stability under heat. With a 1\/2 inch inscribed circle, 3\/16 inch thickness, and 1\/32 inch corner radius, this square-profile insert provides 8 usable cutting edges. The M3 chip breaker geometry delivers controlled chip formation across a broad feed and depth-of-cut range. Licensed machinists and CNC operators working in production turning environments specify this grade for its performance on ferrous workpiece materials.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for steel, stainless steel, and cast iron workpiece materials, corresponding to ISO material groups P and M and K. It supports multi-use applications including turning, boring, and facing operations. The ANSI and ISO standard form factor makes it compatible with SNMG-style toolholders using clamp, pin, or lever-lock holding methods. Maximum depth of cut reaches 0.4685 inches, making it appropriate for moderate to aggressive roughing and semi-finishing passes in both production and job-shop environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCVD multilayer Duratomic coating (TiCN, Al2O3, Cr) for extended tool life on ferrous materials\u003c\/li\u003e\n  \u003cli\u003e8 cutting edges per insert from the square SNMG geometry — reduces cost per edge\u003c\/li\u003e\n  \u003cli\u003eM3 chip breaker optimized for steel and stainless steel chip control across variable feed rates\u003c\/li\u003e\n  \u003cli\u003eChamfered and honed cutting edge style for improved edge toughness and reduced chipping\u003c\/li\u003e\n  \u003cli\u003eCompatible with clamp, pin, and lever-lock SNMG toolholders — no specialty holder required\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI and ISO standards; ISO code SNMG120408-M3 for cross-reference with other suppliers\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in SNMG-style indexable toolholders that accept a 1\/2 inch inscribed circle square insert with a 0.2028 inch hole diameter and N clearance, M tolerance designation.

Power down and lock out the machine before indexing or replacing inserts. Inspect the toolholder pocket and seating surface for wear or debris before seating a new insert — a contaminated pocket will cause premature edge failure. Do not mix insert grades or chip breaker styles within the same toolholder without verifying geometry compatibility.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: SNMG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: SNMG-M3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndustry Standard Number\u003c\/strong\u003e: SNMG432-M3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: SNMG120408-M3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: TP2501\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN, Al2O3, Cr (Duratomic)\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: Square (90 degree included angle)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3\/16 inch (0.1874 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/32 inch (0.0315 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: 0.4685 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\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\u003eNumber of Cutting Edges\u003c\/strong\u003e: 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: M3\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: Steel (ISO P)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Stainless Steel (ISO M), Cast Iron (ISO K)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: P10, P20, P30, P35\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplications\u003c\/strong\u003e: Turning, Boring, Facing\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: 0.02 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 (minimum order quantity 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: SECO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 02959973\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51558482477362,"sku":"02959973","price":255.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/791809807d2ca31ddcb650fab1f58952.jpg?v=1786413458","url":"https:\/\/voomisupply.com\/products\/seco-02959973-turning-insert-snmg432-m3-tp2501-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
