The insert features a CVD-applied multilayer coating of TiN, TiCN, Al2O3, and TiN that delivers high wear resistance across a range of cutting conditions from roughing to medium machining. With a triangular shape, 60-degree included angle, negative rake, and 0-degree relief angle, this insert seats securely in standard TNMG toolholders. The 0.0313-inch corner radius and sharp cutting edge style make it well suited for demanding stock removal passes on steel, stainless steel, and cast iron workpieces.\u003c\/p\u003e\n\u003cp\u003eThe 6780874 insert targets medium to rough turning, facing, and boring applications in production and job-shop environments. Its T9225 grade characteristics span high wear resistance to moderate wear resistance and toughness across P, M, and K workpiece material classifications, covering steel, stainless steel, and cast iron. With six usable cutting edges per insert and compatibility with both clamp and pin holding methods, this insert delivers extended tool life and reduced per-edge cost in high-volume turning operations. It conforms to both ANSI and ISO standards, carrying ANSI code TNMG432 and ISO code TNMG220408.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCVD multilayer coating: TiN over TiCN over Al2O3 over TiN for high wear resistance\u003c\/li\u003e\n  \u003cli\u003e6 usable cutting edges per insert, reducing tooling cost per part\u003c\/li\u003e\n  \u003cli\u003eNeutral hand orientation fits standard TNMG toolholder setups\u003c\/li\u003e\n  \u003cli\u003eChip breaker style TM supports roughing and medium machining chip control\u003c\/li\u003e\n  \u003cli\u003eNegative rake and negative side clearance (clearance code N) for rigid, stable cutting action\u003c\/li\u003e\n  \u003cli\u003eMulti-use application: turning, facing, and boring from a single insert geometry\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-grade replacement and standard production insert for toolholders accepting TNMG 432 inserts with clamp or pin holding methods, per ANSI and ISO seating standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a machinist or toolroom technician familiar with indexable insert toolholders. Disengage spindle power and lock out the machine before seating or indexing the insert. Ensure the insert pocket and seating surface are clean and free of chips before clamping to avoid premature edge failure. Follow the toolholder manufacturer torque guidance for the clamping screw and verify insert seating is flush before resuming cuts.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: TNMG432\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: TNMG220408\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Triangle (T), 60-degree included angle\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: T9225\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: TiN \/ TiCN \/ Al2O3 \/ TiN (multilayer)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: TM (Roughing and Medium Machining)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5000 inches (1\/2 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.8660 inches (22.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1875 inches (3\/16 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0313 inches (1\/32 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.1969 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2030 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: -6 degrees\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\u003eCutting Edge Style\u003c\/strong\u003e: Sharp\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 Holding Method\u003c\/strong\u003e: Clamp or Pin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel (P15, P25), Stainless Steel (M), Cast Iron (K)\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: 0.326 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: TUNGALOY\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6780874\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TUNGALOY","offers":[{"title":"Default Title","offer_id":51972183982386,"sku":"6780874","price":256.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/72a85b6991abb7234fe831b7c637b749.jpg?v=1789963898","url":"https:\/\/voomisupply.com\/products\/tungaloy-6780874-tnmg-432-tm-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
