Manufactured to the Top Notch series standard, this insert carries the KC5025 grade designation and features a physical vapor deposition (PVD) TiAlN finish that improves wear resistance and heat dissipation at the cutting edge. The insert is configured for left-hand, internal UN-standard threads at 8 threads per inch (TPI) with a 60-degree included angle. It is sized as an Insert Size 3 and weighs approximately 0.11 pounds. Machinists and CNC operators working on threaded bore applications will find this insert suited to moderate to high cutting demands in steel and cast iron classifications C2 and C6.\u003c\/p\u003e\u003cp\u003eThis insert is intended for internal threading passes on workpieces requiring UN-standard thread profiles at 8 TPI. The left-hand orientation makes it the correct choice when the tool must traverse in a direction opposite to a standard right-hand insert. Typical installations include production threading on CNC turning centers where Top Notch-compatible toolholders are already in use. The TiAlN coating makes this insert a practical option when cutting ferrous materials or when dry-cutting conditions are preferred to reduce coolant consumption.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKC5025 carbide grade with PVD TiAlN finish for improved wear and thermal resistance\u003c\/li\u003e\n\u003cli\u003eInternal threading geometry with 60-degree included angle for UN-standard thread profiles\u003c\/li\u003e\n\u003cli\u003eLeft-hand insert orientation for reverse-direction threading operations\u003c\/li\u003e\n\u003cli\u003e8 TPI pitch capacity for coarse internal UN threads\u003c\/li\u003e\n\u003cli\u003eTop Notch series form factor for compatibility with Top Notch-style toolholders\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.0071 inches (0.18 mm) for controlled thread root geometry\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in Top Notch series toolholders accepting Insert Size 3 threading inserts.

Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torque driver for the clamping screw to avoid seat damage  -  do not over-tighten by hand. Inspect the insert pocket and clamping surfaces for chips or debris before seating the insert.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NTC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC5025\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2, C6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Top Notch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInternal Pitch\u003c\/strong\u003e: 8 TPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip to Top of Insert\u003c\/strong\u003e: 0.1071 inches (2.72 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0071 inches (0.18 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1949 inches (4.95 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.11 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291804\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: 1799366\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51743886770482,"sku":"1799366","price":210.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cacc61f956f9c14d759dad431243c61c.jpg?v=1788850788","url":"https:\/\/voomisupply.com\/products\/kennametal-1799366-threading-insert-kc5025-carbide-8-tpi","provider":"Voomi Supply","version":"1.0","type":"link"}
