Manufactured to the NTC3R8E geometry in the Top Notch series, this insert features a TiAlN finish applied via PVD coating, which improves wear resistance and tool life in a wide range of threading applications. The insert carries a 60-degree included angle, a corner radius of 0.0161 inches, and a thickness of 0.1949 inches. It is specified in manufacturer grade KC5025, a coated carbide grade suited for threading ferrous and non-ferrous materials at production volumes. Licensed machinists and CNC lathe operators are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for external threading operations on UN-standard fastener and component threads at 8 TPI. The right-hand cut geometry makes it appropriate for standard right-hand thread profiles on turning centers and manual lathes equipped with Top Notch-style toolholders. It is suited for use in production shops, job shops, and maintenance machining environments where consistent thread form and repeatable insert indexing are required. The TiAlN coating supports dry cutting and higher cutting speeds compared to uncoated grades.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTiAlN finish via PVD coating for improved wear resistance and thermal stability\u003c\/li\u003e\n  \u003cli\u003e8 TPI external UN thread profile with 60-degree included angle\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut geometry for standard right-hand thread applications\u003c\/li\u003e\n  \u003cli\u003eKC5025 carbide grade rated for material grades C2 and C6\u003c\/li\u003e\n  \u003cli\u003eTop Notch series insert style (NTC) for secure toolholder seating\u003c\/li\u003e\n  \u003cli\u003eCorner radius of 0.0161 inches for controlled thread root geometry\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in Top Notch series toolholders that accept NTC3 style inserts for external threading.

Power down and lock out the machine spindle before indexing or replacing the insert. Use the appropriate torque wrench and clamping hardware specified for the Top Notch toolholder system  -  do not over-tighten the clamping screw, as this can cause insert cracking. Verify thread pitch, insert orientation, and toolholder alignment before resuming cutting operations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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\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: 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 Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Top Notch\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: 0.0161 inches (0.41 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: 0.031 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: 1765732\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51742889541938,"sku":"1765732","price":243.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3b41ec8bc413c3ca954fe754e5007952_40579f7d-fe1e-464f-98cf-d1d1fe9da257.jpg?v=1788840274","url":"https:\/\/voomisupply.com\/products\/kennametal-1765732-threading-insert-8-tpi-external-un","provider":"Voomi Supply","version":"1.0","type":"link"}
