Carrying the ANSI designation VNMG331EEF and ISO code VNMG160404N-EF, this insert features a 35-degree diamond shape (V) with a neutral cutting direction and a negative rake angle of 20 degrees. The AC5025S grade substrate is coated with TiAlSiN via a PVD process under Sumitomo's Absotech Bronze proprietary coating designation. The EEF chip breaker geometry is optimized for the tighter chip control demands of superalloy machining. Licensed machinists and CNC operators install this insert as a direct screw-lock replacement in compatible toolholders.\u003c\/p\u003e\n\u003cp\u003eThis insert is primarily intended for turning superalloy workpiece materials, classified under Material Grade S20 and Primary Workpiece Material Code S. Typical applications include roughing and finishing passes on nickel-based alloys, titanium, and other difficult-to-machine high-temperature alloys in aerospace, energy, and industrial manufacturing environments. The screw-holding method suits standard VNMG-style toolholders used in production turning operations. The neutral hand designation makes it usable in both right-hand and left-hand cutting configurations depending on toolholder orientation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTiAlSiN PVD coating (Absotech Bronze) for elevated heat resistance during superalloy cutting\u003c\/li\u003e\n  \u003cli\u003eAC5025S carbide grade matched to S20 material classification for superalloy applications\u003c\/li\u003e\n  \u003cli\u003eEEF chip breaker geometry promotes controlled chip formation in tough, work-hardening materials\u003c\/li\u003e\n  \u003cli\u003e35-degree diamond insert shape (V) provides a strong cutting edge with good clearance geometry\u003c\/li\u003e\n  \u003cli\u003e0.0156-inch corner radius balances edge strength with surface finish capability\u003c\/li\u003e\n  \u003cli\u003eScrew-lock insert holding method for positive, repeatable seating in the toolholder pocket\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 screw-lock toolholders accepting a 3\/8-inch inscribed circle, 3\/16-inch thick diamond insert with ANSI code VNMG331EEF.

Before changing inserts, power down the machine and allow all moving components to come to a complete stop. Use the correct torx or hex key specified by the toolholder manufacturer to seat the clamping screw to proper engagement — do not overtighten, as this can fracture the insert. Inspect the toolholder pocket for wear or debris before seating the new insert to ensure accurate indexing.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: VNMG331EEF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: VNMG160404N-EF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond (V), 35-degree included angle\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: VNMG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: AC5025S\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: AC5000S\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: TiAlSiN (Absotech Bronze)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: EEF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative, 20 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: 3\/8 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: 0.1875 inches (3\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 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\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Superalloy (Code S, Grade S20)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3.5 inches L x 1.5 inches W x 0.5 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO 13399\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: 19T6CGW\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51729861050674,"sku":"19T6CGW","price":264.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1f9d430fb028d3d08b441967f6a9d506_7e4cf5e7-20f8-474e-b490-c25ac0992618.jpg?v=1788709604","url":"https:\/\/voomisupply.com\/products\/sumitomo-19t6cgw-turning-insert-vnmg331eef-ac5025s-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
