Part of the Top Notch series, this insert features a TiAlN finish applied via a PVD coating process, which provides wear resistance and thermal stability during threading operations. The insert is right-hand, carries manufacturer grade KC5025, and is suited for material grades C2 and C6. With a 60-degree included angle and a corner radius of 0.0071 inches, it is built to produce accurate UN thread profiles on external workpieces. Machinists and toolroom technicians working on CNC lathes and manual turning centers install this insert into compatible Top Notch toolholders.\u003c\/p\u003e\u003cp\u003eThis insert is intended for external threading applications on UN-standard thread forms at 18 TPI. It is appropriate for production and job-shop environments where consistent thread geometry and tool life are priorities. The KC5025 grade and TiAlN coating make it suitable for a range of ferrous and non-ferrous materials within the C2 and C6 material grade classifications. It fits into the Top Notch insert system, which uses a clamping design common in both manual and CNC turning operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e18 TPI external UN thread form with 60-degree included angle\u003c\/li\u003e\n\u003cli\u003eKC5025 carbide grade with PVD-applied TiAlN finish for wear and heat resistance\u003c\/li\u003e\n\u003cli\u003eRight-hand insert orientation for standard external threading\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.0071 inches (0.18 mm) for precise thread root geometry\u003c\/li\u003e\n\u003cli\u003eTop Notch series compatibility for use with matching Top Notch toolholders\u003c\/li\u003e\n\u003cli\u003eInsert size 3 with a thickness of 0.1949 inches (4.95 mm)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Top Notch series toolholders that accept size 3 NTC-style threading inserts.

Seat the insert fully into the Top Notch toolholder pocket and tighten the clamping screw to the toolholder manufacturer's specified torque using the appropriate Torx or hex key. Inspect the insert seating surface for chips or debris before securing. Replace the insert at the first sign of chipping, built-up edge, or thread-form deviation to avoid workpiece damage.\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\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: External\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExternal Pitch\u003c\/strong\u003e: 18 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 Hand\u003c\/strong\u003e: Right Hand\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\u003eInsert Size\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip to Top of Insert\u003c\/strong\u003e: 0.1480 inches (3.76 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: 0.0207 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: 1799406\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51742368923954,"sku":"1799406","price":244.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3c51e543d04e8a2f058fb0be5803673b.jpg?v=1788837019","url":"https:\/\/voomisupply.com\/products\/kennametal-1799406-threading-insert-18-tpi-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
