It carries the ANSI designation WNMG433MT and ISO code WNMG080412MT, with a TT7025 manufacturer grade. The insert features a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, a combination engineered to deliver moderate wear resistance and toughness suited to cast iron machining. The 80-degree trigon (W-shape) geometry with negative rake and negative side clearance provides six usable cutting edges per insert, reducing per-edge tooling cost. A 0.047-inch corner radius and MT chip breaker geometry make this insert effective for both roughing and medium machining passes.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for turning cast iron workpieces in production and job-shop environments. The TT7025 grade is classified under ISO material group K, targeting cast iron with a balance of wear resistance and edge toughness. The MT chip breaker is suited for moderate-to-heavy depths of cut, making this insert a practical choice on CNC lathes or manual turret lathes where cast iron components such as brake rotors, pump housings, or machine bases are turned at medium-to-high feed rates. A licensed machinist or CNC operator handles installation and edge indexing.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eANSI code WNMG433 \/ ISO code WNMG080412  -  direct cross-reference for toolholder compatibility\u003c\/li\u003e\n  \u003cli\u003eTT7025 grade with CVD TiCN + Al2O3 + TiN multilayer coating for cast iron performance\u003c\/li\u003e\n  \u003cli\u003eSix cutting edges per insert for extended tooling economy\u003c\/li\u003e\n  \u003cli\u003eMT chip breaker geometry supports roughing and medium machining operations\u003c\/li\u003e\n  \u003cli\u003e0.047-inch corner radius balances edge strength and surface finish\u003c\/li\u003e\n  \u003cli\u003eNegative rake, negative side clearance (clearance code N, tolerance code M) for rigid, stable clamping\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in WNMG-style toolholders accepting an ANSI size 433 insert with a clamp-style holding method.

Use the correct torque wrench and clamp hardware specified by the toolholder manufacturer  -  do not overtighten the clamp screw, as carbide inserts are brittle and can crack under excessive clamping force. Inspect the insert pocket and clamp for wear or debris before seating a new edge. Follow the machine tool builder and shop safety guidelines for workholding and guarding when 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: WNMG433\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: WNMG080412\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: TT7025\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, TiN (CVD process)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: W - Trigon 80-degree\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: 0.5000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.343 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.187 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.047 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.157 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\u003eChip Breaker\u003c\/strong\u003e: MT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker Operation\u003c\/strong\u003e: Roughing, Medium Machining\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\u003eSide Clearance\u003c\/strong\u003e: Negative\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\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron (ISO group K)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade Characteristics\u003c\/strong\u003e: Moderate wear resistance and toughness to high toughness for cast iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: INGERSOLL CUTTING TOOLS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6187837\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"INGERSOLL CUTTING TOOLS","offers":[{"title":"Default Title","offer_id":52001107050802,"sku":"6187837","price":31.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a8a462c2935eb6a237c5b8149b7425f0_f99d33c2-2c04-44ca-a977-274485d6f7fd.jpg?v=1789996938","url":"https:\/\/voomisupply.com\/products\/ingersoll-cutting-tools-6187837-wnmg433mt-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
