Running in the Top Notch series, it carries the NTC3R20E geometry and is manufactured to a KC730 grade with a Titanium Nitride (TiN) finish applied via PVD coating. The insert cuts UN-standard external threads at 20 TPI with a 60-degree included angle and a right-hand orientation. The corner radius measures 0.0062 inches (0.16 mm) and the tip-to-top height is 0.1480 inches (3.76 mm). Machinists and CNC operators use this insert for threading steel, cast iron, and similar C2-C4 material-grade workpieces in production turning applications.\u003c\/p\u003e\u003cp\u003eThis insert is suited for external threading operations in both job-shop and production environments where consistent thread form and tool life matter. The KC730 PVD-coated carbide grade is commonly selected for threading steel and ferrous materials where edge toughness and wear resistance are priorities. The Top Notch insert system uses a notch-style clamping mechanism, which positions and locks the insert securely in compatible Top Notch threading toolholders. Applications include producing UN-form external threads on shafts, fasteners, fittings, and similar turned components.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKC730 carbide grade with PVD-applied Titanium Nitride (TiN) coating for wear resistance on ferrous materials\u003c\/li\u003e\n\u003cli\u003e20 TPI external UN thread form with 60-degree included angle\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting orientation\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.0062 inches (0.16 mm) for accurate thread root geometry\u003c\/li\u003e\n\u003cli\u003eTop Notch series notch-clamp design for repeatable insert positioning\u003c\/li\u003e\n\u003cli\u003eInsert size 3 with tip-to-top height of 0.1480 inches and thickness of 0.1949 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in Top Notch series threading toolholders that accept size 3 NTC-style inserts.

Ensure the machine spindle is stopped and the turret is in a safe index position before changing inserts. Seat the insert fully into the Top Notch holder pocket and verify the notch engagement before clamping. Do not overtighten the clamp screw; use the toolholder manufacturer's recommended clamp torque procedure. Inspect the insert edge and corner radius condition at regular intervals to maintain thread form accuracy.\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\u003eManufacturer Grade\u003c\/strong\u003e: KC730\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: Titanium Nitride (TiN)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: External\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExternal Pitch\u003c\/strong\u003e: 20 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\u003eMaterial Grade\u003c\/strong\u003e: C2, C3, C4\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: 0.0062 inches (0.16 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: 0.0238 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: 1182186\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51732086915378,"sku":"1182186","price":237.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/38b30a40760df88dd66382970fbed794.jpg?v=1788739053","url":"https:\/\/voomisupply.com\/products\/kennametal-1182186-threading-insert-20-tpi-kc730-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
