This uncoated, multi-tipped insert features an 80-degree diamond shape, a 0.5-inch inscribed circle, and a flat-top chip breaker geometry. It carries manufacturer grade CBN010 and a chamfered and honed cutting edge style. With a negative rake angle and neutral hand, it fits standard CNGA-style toolholders and is well suited for CNC turning operations on hard and difficult materials. Machinists and tooling specialists working in production turning environments will find this insert appropriate for demanding stock removal on hardened workpieces.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for turning, facing, and boring operations on hard materials and super-alloys, including titanium. The CNGA 431 geometry and PCBN substrate make it a common choice for finish and semi-finish turning of hardened steels and heat-resistant alloys where carbide inserts fall short. It is compatible with CNGA-style insert pockets that use clamp, pin, or lever-lock holding methods. The flat-top chip breaker and chamfered edge preparation help maintain edge stability at elevated cutting temperatures typical of hard turning applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePCBN substrate, uncoated, manufacturer grade CBN010 for hard and super-alloy workpiece materials\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond insert shape (Shape Code C) with chamfered and honed cutting edge\u003c\/li\u003e\n  \u003cli\u003e0.5-inch inscribed circle with 1\/64-inch (0.0157-inch) corner radius\u003c\/li\u003e\n  \u003cli\u003eFlat-top chip breaker, negative rake, neutral hand — 2 cutting edges per insert\u003c\/li\u003e\n  \u003cli\u003eCompatible with clamp, pin, and lever-lock toolholder systems\u003c\/li\u003e\n  \u003cli\u003eMulti-use application: turning, facing, and boring\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI and ISO standards; ISO code CNGA120404S-01020-L1-B\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNGA-style toolholders with clamp, pin, or lever-lock insert holding methods.

Ensure the machine spindle is fully stopped and the turret is indexed away from the work zone before seating or removing the insert. Use the appropriate torque driver for the clamping screw per the toolholder manufacturer specification. Inspect the insert pocket and seating surface for chips or debris before installing a new insert to prevent rocking or improper seating.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: CNGA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond 80 (Shape Code C)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Polycrystalline Cubic Boron Nitride (PCBN)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: CBN010\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: H01, H10, H20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0157 inches (1\/64 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1874 inches (3\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.5079 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTip Length\u003c\/strong\u003e: 0.1060 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2028 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.0200 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: Flat Top\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 0 degrees (Negative Rake)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees (Clearance Code N)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Chamfered and Honed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWiper Edge\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated (Bright)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp, Pin, Lever Lock\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMulti-Use Application\u003c\/strong\u003e: Boring, Facing, Turning\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Hard Material (H)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Super-alloys and Titanium (S)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: CNGA120404S-01020-L1-B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndustry Standard Number\u003c\/strong\u003e: CNGA431S-00420-L1-B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CNGA Flat Top (Secomax)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: SECO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 02825918\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51562651386162,"sku":"02825918","price":116.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/174aa8c407b22598d98890b528787ac1.jpg?v=1786481594","url":"https:\/\/voomisupply.com\/products\/seco-02825918-pcbn-turning-insert-cnga-431-diamond","provider":"Voomi Supply","version":"1.0","type":"link"}
