Manufactured in the NJK insert style with a KC5010 grade carbide substrate, it features a TiAlN finish applied via PVD coating for wear resistance during precision threading operations. The 60-degree included angle is standard for UNJ thread profiles. At 0.1949 inches thick with a tip-to-top dimension of 0.1409 inches and a corner radius of 0.0059 inches, this insert is engineered for consistent thread geometry. It is used by machinists and toolroom technicians running CNC lathes or manual threading operations on precision components.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for external threading applications requiring UNJ thread standards, which are common in aerospace and high-reliability mechanical assemblies. The right-hand cutting orientation and Top Notch series toolholder interface make it compatible with KENNAMETAL Top Notch threading toolholders accepting the 3006 insert size. The KC5010 grade and PVD TiAlN coating support threading in a range of engineering materials including C3 and C4 material grades, covering a broad spectrum of hardened and difficult-to-machine alloys.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNJK insert style in size 3006 for Top Notch series toolholder compatibility\u003c\/li\u003e\n  \u003cli\u003eKC5010 carbide grade with PVD-applied TiAlN finish for wear and heat resistance\u003c\/li\u003e\n  \u003cli\u003e28 TPI external UNJ thread form with 60-degree included angle\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting orientation\u003c\/li\u003e\n  \u003cli\u003eCorner radius of 0.0059 inches (0.15 mm) for accurate thread root profile\u003c\/li\u003e\n  \u003cli\u003eC3 and C4 material grade classification for broad workpiece compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in KENNAMETAL Top Notch series threading toolholders accepting 3006-size NJK style inserts.

Use the appropriate torque wrench and insert screw specified for the Top Notch toolholder to secure the insert without over-tightening. Inspect the toolholder pocket for chips or damage before seating a new insert. Verify thread pitch and hand orientation against the workpiece drawing before commencing any threading pass.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NJK\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 3006\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: KC5010\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C3, C4\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: UNJ\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: External\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExternal Pitch\u003c\/strong\u003e: 28 TPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\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: 0.1409 inches (3.58 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0059 inches (0.15 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\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: 1796449\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":52026335363378,"sku":"1796449","price":250.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/79723eede3cfd88629798499e470e4e4.jpg?v=1790016293","url":"https:\/\/voomisupply.com\/products\/kennametal-1796449-threading-insert-28-tpi-kc5010-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
