It carries the industry standard designation CNGA432T0420 and the manufacturer grade KY1540, a high wear-resistance ceramic formulated for superalloys and titanium workpiece materials. The insert features an 80-degree diamond (rhombic) shape, a T-Land cutting edge style, and a flat-top chip breaker. With a 0.5-inch inscribed circle, a 3\/16-inch thickness, and a 1\/32-inch corner radius, this insert is built for stable, precise cuts in demanding materials where carbide grades reach their performance limits.\u003c\/p\u003e\u003cp\u003eThis insert is suited for turning, facing, and boring operations on hardened materials, superalloys, and titanium components in precision machining environments. The neutral hand orientation makes it adaptable across a range of tool holders that accept CNGA-style inserts. The negative rake and negative side clearance geometry provide edge strength critical when cutting hard or abrasive workpiece materials. Maximum depth of cut is 0.0492 inches (1.25 mm), reflecting its application as a finishing or light semi-finishing insert rather than a heavy roughing tool. Machinists and tool-room professionals working with aerospace-grade alloys or hardened steel components will find this insert appropriate for that class of work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGrade KY1540 uncoated ceramic optimized for high wear-resistance in superalloy and titanium applications\u003c\/li\u003e\n\u003cli\u003e80-degree diamond (CNGA) insert shape with T-Land cutting edge for controlled edge strength\u003c\/li\u003e\n\u003cli\u003eFlat-top chip breaker geometry with negative rake and 0-degree relief angle\u003c\/li\u003e\n\u003cli\u003eFour cutting edges per insert for extended tool life across multiple setups\u003c\/li\u003e\n\u003cli\u003eNeutral hand orientation compatible with CNGA-style clamp and pin holding systems\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut 0.0492 inches (1.25 mm) suited to finishing and light semi-finishing passes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in tool holders accepting CNGA432 inserts with clamp and pin holding methods per ANSI and ISO standards (ANSI Insert Code: CNGA432; ISO Insert Code: CNGA120408).

Ensure the machine spindle is fully stopped and the tool holder is secured before seating or replacing the insert. Use the appropriate torque wrench on the clamping screw per the tool holder manufacturer specification — do not overtighten. Inspect the insert pocket and seating surfaces for chips or debris before installation, as contamination can cause premature edge failure or insert fracture during a cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndustry Standard Number\u003c\/strong\u003e: CNGA432T0420\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\u003eManufacturer Grade\u003c\/strong\u003e: KY1540\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Ceramic, Uncoated\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\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 Length\u003c\/strong\u003e: 0.5077 inches (12.90 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1875 inches (3\/16 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0313 inches (1\/32 inch)\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\u003eCutting Edge Style\u003c\/strong\u003e: T-Land\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: Flat Top\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\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: 4\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: Superalloys and Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: KENLOC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C4\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 insert per package (minimum order quantity: 5)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0062 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: 1943835\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51730750079282,"sku":"1943835","price":271.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2c064b9c2ae4c23837e3f2ee6fb7f13e.jpg?v=1788722201","url":"https:\/\/voomisupply.com\/products\/kennametal-1943835-ceramic-turning-insert-cnga432t0420","provider":"Voomi Supply","version":"1.0","type":"link"}
