It carries the ANSI insert code CNGA432 and the ISO code CNGA120408, placing it in the KENLOC series with a neutral hand orientation and negative rake geometry. The 80-degree diamond (rhombic) insert shape provides a strong cutting edge, while the chamfered and honed edge preparation extends tool life under demanding conditions. Two cutting edges are available per insert. This insert is installed by machinists and tooling specialists in CNC turning, facing, and boring operations where CBN-grade performance is required.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for finishing and semi-finishing applications on hard materials including hardened steels, cast iron grades, and select super alloys. Its flat-top chip breaker geometry and uncoated bright finish are specified for applications where the PCBN substrate itself provides the required wear resistance without an additional coating. The KENLOC series clamping system uses a clamp and pin holding method, making this insert compatible with standard CNGA-style toolholders. Typical applications include external turning, facing passes, and boring on horizontal or vertical CNC lathes and machining centers.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePCBN insert material delivers high wear resistance on hard workpiece materials and cast iron\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond (rhombic) insert shape with negative rake and zero-degree relief angle for maximum edge strength\u003c\/li\u003e\n  \u003cli\u003eChamfered and honed cutting edge preparation reduces chipping and extends insert life\u003c\/li\u003e\n  \u003cli\u003eTwo cutting edges per insert maximize value per unit\u003c\/li\u003e\n  \u003cli\u003eFlat-top chip breaker geometry supports turning, facing, and boring operations\u003c\/li\u003e\n  \u003cli\u003eClamp and pin holding method provides secure seating in KENLOC-compatible toolholders\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI and ISO dimensional standards for consistent interchangeability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNGA-style toolholders compatible with the KENNAMETAL KENLOC clamping system.

The machine spindle must be stopped and all moving components fully arrested before indexing or replacing the insert. Inspect the toolholder pocket and locating surfaces for chips or debris before seating the insert, as contamination can cause improper seating and premature edge failure. Follow the toolholder manufacturer's clamping torque specifications and the applicable shop safety procedures when handling PCBN inserts, as the cutting edges are extremely sharp.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Polycrystalline Cubic Boron Nitride (PCBN)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: CNGA432\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: CNGA120408\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: C - Diamond (Rhombic) 80 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KB1630\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: H25, H35\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: KENLOC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5000 inches (1\/2 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.5077 inches (12.90 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Width\u003c\/strong\u003e: 0.5000 inches (1\/2 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: 0.0313 inches (1\/32 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2031 inches (5.16 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.0492 inches (1.25 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\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\u003eSide Clearance\u003c\/strong\u003e: Negative\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\u003eChip Breaker\u003c\/strong\u003e: Flat Top\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Chamfered, Honed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated (Bright)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWiper Edge\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp, Pin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Hard Material, Cast Iron (K), Special and Super Alloys (S)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMulti-Use Application\u003c\/strong\u003e: Turning, Facing, Boring\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 pounds\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: KENNAMETAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3652767\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51747651944754,"sku":"3652767","price":192.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e7d147c7caddd01d0be84c00d678350e_29e79ca9-e9d0-42fa-b069-0e19ebbe2f5c.jpg?v=1788884082","url":"https:\/\/voomisupply.com\/products\/kennametal-3652767-pcbn-turning-insert-cnga432-kb1630","provider":"Voomi Supply","version":"1.0","type":"link"}
