It carries the industry standard designation SNG644T0420 and is manufactured to a KYS30 SiAlON ceramic grade, which delivers moderate wear resistance and toughness in demanding S-category workpiece applications. The insert features a 3\/4 inch inscribed circle, a 1\/4 inch thickness, a 1\/16 inch corner radius, and a flat-top chip breaker geometry with a T-Land cutting edge. The negative rake and negative side clearance geometry are engineered for rigidity under the high cutting forces typical of nickel-base and titanium alloys.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for turning, facing, and boring operations on superalloys and titanium in aerospace, power generation, and industrial machining environments. The square SNG insert shape provides eight available cutting edges, improving cost-per-edge economics on production runs. The uncoated SiAlON ceramic construction performs at elevated cutting speeds where carbide grades lose thermal stability. It is intended for use in rigid setups with appropriate SNG-style clamp toolholders operating at parameters recommended for ceramic grades in S-category materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKYS30 SiAlON ceramic grade — optimized for moderate wear resistance and toughness in superalloy and titanium turning\u003c\/li\u003e\n  \u003cli\u003eEight cutting edges per insert on a square SNG geometry, maximizing edge utilization\u003c\/li\u003e\n  \u003cli\u003eT-Land cutting edge style with flat-top chip breaker for controlled chip formation in difficult-to-machine alloys\u003c\/li\u003e\n  \u003cli\u003eNegative rake and negative side clearance (N clearance code) for high-rigidity, high-force cutting applications\u003c\/li\u003e\n  \u003cli\u003eUncoated bright finish — no coating process introduces thermal mismatch risk at ceramic cutting speeds\u003c\/li\u003e\n  \u003cli\u003eMulti-use geometry supports turning, facing, and boring from a single insert style\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in SNG-style clamp toolholders compatible with the SNG644 insert size.

Ensure the machine spindle is fully stopped and the toolholder is properly seated and torqued before indexing or replacing the insert. Ceramic inserts require rigid machine setups and are sensitive to interrupted cuts and vibration — verify setup stability before engaging the workpiece. Follow the tooling manufacturer's recommended cutting parameters for SiAlON ceramic grades when operating on superalloys or titanium.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndustry Standard Number\u003c\/strong\u003e: SNG644T0420\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: SNG644\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: SNG190616\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: SNGN190616T01020\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Ceramic (SiAlON)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KYS30\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated (Bright)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: S - Square\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/4 inch (0.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 1\/4 inch (0.2500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 3\/4 inch (0.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/16 inch (0.0625 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.2498 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 8\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\u003eInsert Hand\u003c\/strong\u003e: Neutral\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\u003eClearance Code\u003c\/strong\u003e: N\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: G\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Superalloys and Titanium (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\u003eSeries\u003c\/strong\u003e: KENDEX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.033 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: 4146453\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51733691793714,"sku":"4146453","price":537.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/02f5bbd4d0e74cc43761e6f7676be920.jpg?v=1788758299","url":"https:\/\/voomisupply.com\/products\/kennametal-4146453-ceramic-turning-insert-sng644t0420","provider":"Voomi Supply","version":"1.0","type":"link"}
