Manufactured to ANSI code CNMG431EGU and ISO code CNMG120404N-GU, this insert features an 80-degree diamond shape with a neutral hand orientation and a positive rake angle of 16 degrees. The AC820P grade substrate is finished with a PVD-applied ZX proprietary coating, enhancing wear resistance and edge integrity during interrupted and continuous turning operations. The EGU chip breaker geometry promotes controlled chip evacuation. Installed by machinists and CNC operators, this insert fits standard CNMG-style toolholders secured by clamp and pin holding methods.\u003c\/p\u003e\u003cp\u003eThis insert is suited for turning applications on steel workpieces, corresponding to ISO material group P and material grades C2 and C3. The EGU chip breaker geometry is optimized for finishing and semi-finishing passes where chip control and surface finish consistency are priorities. Typical install scenarios include production turning on CNC lathes in job shops and manufacturing facilities. The neutral hand designation allows use in both right-hand and left-hand toolholder configurations that accept CNMG geometry inserts.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eANSI code CNMG431EGU with ISO equivalent CNMG120404N-GU for international toolholder compatibility\u003c\/li\u003e\n\u003cli\u003eAC820P grade with PVD-applied ZX coating for wear resistance on steel cutting applications\u003c\/li\u003e\n\u003cli\u003e80-degree diamond insert shape with 0-degree relief angle (clearance code N, tolerance code M)\u003c\/li\u003e\n\u003cli\u003eEGU chip breaker with 16-degree positive rake angle for controlled chip evacuation\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.0313 inches (1\/32 inch) for fine edge geometry on finishing passes\u003c\/li\u003e\n\u003cli\u003eCompatible with clamp and pin holding systems standard on CNMG toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement turning insert for CNC toolholders accepting CNMG-style inserts with clamp and pin holding.

Use the appropriate torque wrench and clamp screws specified by the toolholder manufacturer — do not over-tighten clamp fasteners by hand estimation. Inspect the toolholder pocket for chips, debris, or wear before seating the insert. Follow the toolholder manufacturer's guidelines and applicable shop safety standards when handling carbide inserts, as edges are sharp.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: CNMG431EGU\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: CNMG120404N-GU\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: CNMG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond (80 degrees)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: AC820P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: PVD Coated (ZX Proprietary Designation)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: EGU\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: Positive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 16 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\u003eInscribed Circle\u003c\/strong\u003e: 0.5000 inches (12.70 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.5079 inches\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\u003eHole Diameter\u003c\/strong\u003e: 0.2031 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp and Pin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 431\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Steel (ISO Code P)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2, C3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO 13399\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SUMITOMO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 19RJ334\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51735993680178,"sku":"19RJ334","price":189.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0943e89bb81986a1bfaa18364fdaec6c.jpg?v=1788775309","url":"https:\/\/voomisupply.com\/products\/sumitomo-19rj334-turning-insert-cnmg431egu-ac820p-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
