It follows the VCGT331 ANSI insert code and the VCGT160404 ISO insert code, placing it in the V-shape diamond (rhombic) 35-degree geometry family. The insert carries a polished ACN15K grade coating and a positive side clearance with a 7-degree relief angle. With a corner radius of 0.0157 inches (0.40 mm) and a maximum depth of cut of 0.0531 inches (1.35 mm), it is suited for light to moderate finishing passes where dimensional accuracy and surface finish are the priority. The LMF+ chip breaker geometry supports controlled chip evacuation during those cuts.\u003c\/p\u003e\u003cp\u003eThis insert is applied in turning operations on cast iron and non-ferrous materials such as aluminum, brass, and other soft metals. The ACN15K grade is rated for high to moderate wear resistance with corresponding toughness in K-class (cast iron) and N-class (aluminum and non-ferrous) workpiece materials. It is a neutral-hand insert, making it suitable for both right-hand and left-hand tool holders that accept the VCGT geometry. Machinists and CNC operators working in job shops, production turning cells, and maintenance machining environments are the primary users.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eVCGT331 (ANSI) and VCGT160404 (ISO) insert codes for direct cross-reference and tool holder selection\u003c\/li\u003e\n\u003cli\u003eACN15K carbide grade with polished finish for high wear resistance in cast iron and non-ferrous applications\u003c\/li\u003e\n\u003cli\u003e35-degree diamond (rhombic) insert shape provides a sharp, low-force cutting edge geometry\u003c\/li\u003e\n\u003cli\u003e0.0157 inch (0.40 mm) corner radius supports tight-tolerance finishing and light profiling\u003c\/li\u003e\n\u003cli\u003eLMF+ chip breaker geometry promotes controlled chip formation at light depths of cut\u003c\/li\u003e\n\u003cli\u003eNeutral insert hand fits both right-hand and left-hand VCGT-compatible tool holders\u003c\/li\u003e\n\u003cli\u003eScrew-mount insert holding method for repeatable indexing and secure clamping\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in screw-clamp tool holders accepting the VCGT geometry with a ANSI size code of 331 and ISO size code of 160404.

Use the appropriate Torx or hex key specified by the tool holder manufacturer to seat the screw-clamp; do not overtighten, as carbide inserts are brittle and can crack under excessive clamping force. Verify insert seating and pocket cleanliness before resuming cutting operations. Always wear cut-resistant gloves when handling indexable carbide inserts.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: VCGT331\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: VCGT160404\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: VCGT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: V - Diamond (Rhombic) 35 Degree\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 35 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 7 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0157 inches (0.40 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.3752 inches (9.53 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1874 inches (4.76 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1744 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.0531 inches (1.35 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: ACN15K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Polished\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: LMF+\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Positive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron (K), Aluminum and Non-Ferrous (N)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 75332155\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51729424908594,"sku":"75332155","price":312.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d9a0189116fe0092a492589d94fac58b.jpg?v=1788704469","url":"https:\/\/voomisupply.com\/products\/accupro-75332155-turning-insert-vcgt331-carbide-diamond","provider":"Voomi Supply","version":"1.0","type":"link"}
