It carries the ANSI designation VNMG331ESU and the ISO code VNMG160404N-SU, and is manufactured to ANSI and ISO 13399 standards. The insert features a TiAlSiN coating applied via PVD process under Sumitomo's proprietary Absotech Bronze designation, providing high heat resistance and edge stability at elevated cutting speeds. With a 35-degree diamond shape, negative rake angle of 13 degrees, and an ESU chip breaker geometry, it is suited for finishing and semi-finishing passes in turning applications. Machining professionals and CNC operators install this insert in compatible tool holders as part of the AC5000S series.\u003c\/p\u003e\u003cp\u003eThis insert is intended for turning non-ferrous metals and superalloys, corresponding to material grade codes N and S. The neutral cutting direction makes it compatible with both left-hand and right-hand tool holder setups. Typical applications include external turning, facing, and contour work on materials such as aluminum alloys, copper alloys, titanium, and nickel-based superalloys. The ESU chip breaker geometry is optimized for light to medium depth-of-cut scenarios where controlled chip formation and surface finish quality are priorities. It is used in production machining environments by CNC machinists and tool-and-die professionals.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eANSI designation VNMG331ESU with ISO code VNMG160404N-SU, meeting ANSI and ISO 13399 standards\u003c\/li\u003e\n\u003cli\u003eTiAlSiN PVD coating under the Absotech Bronze designation for heat resistance and extended tool life\u003c\/li\u003e\n\u003cli\u003e35-degree diamond insert shape with negative rake for controlled edge engagement\u003c\/li\u003e\n\u003cli\u003eESU chip breaker geometry suited for finishing and semi-finishing cuts in non-ferrous and superalloy materials\u003c\/li\u003e\n\u003cli\u003eNeutral cutting direction compatible with both left-hand and right-hand tool holders\u003c\/li\u003e\n\u003cli\u003eScrew-lock insert holding method for secure seating in compatible VNMG-style holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with VNMG-style screw-lock turning tool holders compatible with the AC5000S series.

Power down and lock out the machine spindle before changing inserts. Use the appropriate torx or hex key to secure the clamping screw to the tool holder manufacturer's specified procedure without over-torquing, which can crack the insert. Inspect the insert pocket for chips or debris before seating the insert to ensure proper contact and runout.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: VNMG331ESU\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: VNMG160404N-SU\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\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: AC5015S\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: AC5000S\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlSiN (Absotech Bronze, PVD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inches (0.3750 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\u003eInsert Thickness\u003c\/strong\u003e: 3\/16 inches (0.1875 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\u003eHole Diameter\u003c\/strong\u003e: 0.1500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 13 degrees (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\u003eChip Breaker\u003c\/strong\u003e: ESU\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Neutral\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: Non-Ferrous Metal, Superalloy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade Code\u003c\/strong\u003e: N, S\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: 0.1 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 insert per package\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\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: 19T5APR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51737112314162,"sku":"19T5APR","price":264.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7cebf4d3c67531e3a8f3edca4700223b.jpg?v=1788784439","url":"https:\/\/voomisupply.com\/products\/sumitomo-19t5apr-carbide-turning-insert-vnmg331esu-ac5015s","provider":"Voomi Supply","version":"1.0","type":"link"}
