It carries the CNGA insert style with an 80-degree diamond shape, a 0.5-inch inscribed circle, and a 0.0315-inch corner radius. The insert features a TiAlSiN multilayer PVD coating applied via PCBN process and is classified under manufacturer grade CBN060K with material grades H10 and H20. With a chamfered and honed cutting edge and negative rake geometry, it is suited for finishing and semi-finishing operations in hard turning. Licensed machinists and CNC turning specialists working with hardened steels, cast irons, and similar materials are the primary installers and operators of this insert.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for use in CNC turning, facing, and boring operations on hard materials and super-alloys including titanium. It fits into CNGA-style toolholders using clamp, pin, or lever lock holding methods. The flat-top chip breaker design and neutral hand orientation make it applicable across a range of turning setups. It conforms to both ANSI and ISO standards, with an ISO code of CNGA120408S-01525-L1-B and an industry standard number of CNGA432S-00625-L1-B. The insert size code is 432. This is a multi-tipped insert with 2 cutting edges, supporting extended tool life in production environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePCBN substrate with TiAlSiN multilayer PVD coating for wear resistance in hard turning\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond insert shape (Shape Code C) with negative rake and 0-degree relief angle\u003c\/li\u003e\n  \u003cli\u003e0.5-inch inscribed circle and 0.0315-inch corner radius for consistent geometry\u003c\/li\u003e\n  \u003cli\u003e2 cutting edges with chamfered and honed edge preparation\u003c\/li\u003e\n  \u003cli\u003eCompatible with clamp, pin, and lever lock toolholder systems\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI and ISO standards; usable for boring, facing, and turning\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNGA-style toolholders accepting insert size 432.

Use the appropriate torque driver per the toolholder manufacturer's clamping specification — do not overtighten or substitute fasteners. Inspect the insert seat and clamping pocket for debris or damage before installation. Handle PCBN inserts with care, as the cutting edges are brittle and susceptible to chipping from impact or improper handling.\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\u003eIncluded Angle\u003c\/strong\u003e: 80 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1874 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\u003eCorner Radius\u003c\/strong\u003e: 0.0315 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\u003eTip Length\u003c\/strong\u003e: 0.0940 inches\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\u003eRake Angle\u003c\/strong\u003e: 0 degrees (Negative Rake)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 2\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\u003eChip Breaker\u003c\/strong\u003e: Flat Top\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\u003eCoating\u003c\/strong\u003e: TiAlSiN Multilayer PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: CBN060K\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: H10, H20\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Hard Material (Code H)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Super-alloys and Titanium (Code S)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CNGA-Flat Top (Secomax)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: CNGA120408S-01525-L1-B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndustry Standard Number\u003c\/strong\u003e: CNGA432S-00625-L1-B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 432\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMulti-Use Applications\u003c\/strong\u003e: Boring, Facing, Turning\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\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: 02686682\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51563787190578,"sku":"02686682","price":1553.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ab5a3b1a7476047e296ffb05b6c7d5ad.jpg?v=1786503521","url":"https:\/\/voomisupply.com\/products\/seco-02686682-pcbn-turning-insert-cnga432s-00625l1-b","provider":"Voomi Supply","version":"1.0","type":"link"}
