Carrying the G10E uncoated carbide grade, this insert operates with a positive rake geometry and a 10-degree rake angle, making it well suited for finishing and light interrupted cuts. The 35-degree diamond shape (Insert Shape Code V) concentrates cutting force on a narrow tip for accurate profiling. With a 1\/64 inch corner radius and a 3\/8 inch inscribed circle, it delivers clean surface finishes in tight-tolerance applications. Machinists and tool-and-die professionals install this insert as a direct OEM-grade replacement in compatible turning toolholders.\u003c\/p\u003e\n\u003cp\u003eThis insert is primarily intended for turning cast iron workpieces, corresponding to material grade K and material grade designation C2. It is used in both production turning and job-shop environments where an uncoated carbide grade outperforms coated alternatives — particularly in abrasive, short-chip cast iron cuts where coating adhesion or thermal buildup is a concern. The EUP chip breaker geometry controls chip flow during finishing passes. Insert holding is achieved via clamp and pin methods standard to VNMG-compatible toolholders. The neutral hand orientation allows use in both standard and back-turning configurations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide G10E uncoated grade optimized for cast iron (K-class) turning\u003c\/li\u003e\n  \u003cli\u003e35-degree diamond insert shape with positive rake for reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003eEUP chip breaker geometry for controlled chip evacuation during finishing\u003c\/li\u003e\n  \u003cli\u003e1\/64 inch corner radius for fine surface finish and tight-tolerance profiling\u003c\/li\u003e\n  \u003cli\u003eNeutral hand orientation supports standard and back-turning setups\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI code VNMG331EUP and ISO 13399 code VNMG160404N-UP\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement turning insert for VNMG-style toolholders accepting a 3\/8 inch inscribed circle insert with clamp and pin holding.

Confirm that the toolholder seat and clamp are free of chips and debris before seating the insert. Tighten the clamp to toolholder manufacturer specifications — do not substitute torque values from memory or unrelated documentation. Dispose of worn inserts in accordance with local regulations for carbide tooling waste.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: VNMG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: VNMG331EUP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: VNMG160404N-UP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond (35 degrees)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape Code\u003c\/strong\u003e: V\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: G10E\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Uncoated\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: 10 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: EUP\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: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.6535 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3\/16 inch (0.1875 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inch (0.0156 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1500 inches\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 and Pin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron (Code K)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: VN\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: 0.025 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: SUMITOMO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1934374\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51748634460466,"sku":"1934374","price":216.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/270b46c89e3afc6bc6b8447e63815b4a.jpg?v=1788895992","url":"https:\/\/voomisupply.com\/products\/sumitomo-1934374-turning-insert-vnmg331eup-g10e-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
