Carrying the industry standard designation CNGA431S0525MT, this insert features an 80-degree diamond (rhombic) shape with a 0.5-inch inscribed circle and a 1\/64-inch (0.0156-inch) corner radius. The grade KBH20 PCBN substrate is finished with a multilayer PVD TiN\/AlTiN nano-composite coating, producing a chamfered and honed cutting edge suited for continuous cuts in hardened steels and other H-group workpiece materials. Two cutting edges are available per insert, and the flat-top chip breaker geometry supports turning, facing, and boring operations.\u003c\/p\u003e\u003cp\u003eThis insert is intended for use in demanding hard-turning applications where carbide tooling reaches its performance limits. Typical workpiece materials include hardened steels, hardened cast irons, and similar H15 and H25 material grades. The KENLOC series insert is held by clamp or pin mounting in compatible toolholders and runs as a neutral-hand insert, making it adaptable across common CNC turning centers and boring setups in both production and job-shop environments. Licensed machinists and CNC operators working in aerospace, automotive, die-and-mold, and general precision machining will encounter this insert in high-speed finishing and semi-finishing passes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePCBN nano-composite construction with multilayer PVD TiN\/AlTiN coating for wear resistance in hard materials\u003c\/li\u003e\n\u003cli\u003e80-degree diamond (rhombic) insert shape with 0.5-inch inscribed circle and negative rake\/clearance geometry\u003c\/li\u003e\n\u003cli\u003eChamfered and honed cutting edge style for edge strength and controlled entry into hardened workpieces\u003c\/li\u003e\n\u003cli\u003eTwo cutting edges per insert with flat-top chip breaker for turning, facing, and boring versatility\u003c\/li\u003e\n\u003cli\u003eCompatible with clamp and pin insert-holding methods in KENLOC-series toolholders\u003c\/li\u003e\n\u003cli\u003eConforms to ANSI and ISO dimensional standards (ANSI: CNGA431, ISO: CNGA120404)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement insert conforming to ANSI code CNGA431 and ISO code CNGA120404.

Use the appropriate torquing tool and seating procedure specified by the toolholder manufacturer when securing the clamp or locating pin — do not rely on feel alone to confirm seating. Inspect the toolholder pocket and seating surface for chips or wear before placing the new insert. Proper edge orientation and insert indexing should be confirmed before resuming cuts.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndustry Standard Number\u003c\/strong\u003e: CNGA431S0525MT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: CNGA431\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: CNGA120404\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: KBH20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiN \/ AlTiN Multilayer PVD Nano-Composite\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\u003eInscribed Circle\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.508 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0156 inches (1\/64 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2031 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.1692 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\u003eCutting Edge Style\u003c\/strong\u003e: Chamfered and Honed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: Negative (0 degrees)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp and Pin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Hard Material (H-code)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Material Grades\u003c\/strong\u003e: H15, H25\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\u003eSeries\u003c\/strong\u003e: KENLOC\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: 0.012 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: KENNAMETAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5330695\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51751604551986,"sku":"5330695","price":142.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e7d147c7caddd01d0be84c00d678350e_ef88b7bc-2c5e-4989-add7-49d77a22232b.jpg?v=1788923917","url":"https:\/\/voomisupply.com\/products\/kennametal-5330695-pcbn-turning-insert-cnga431s0525mt","provider":"Voomi Supply","version":"1.0","type":"link"}
