Manufactured in the NJK style as part of the Top Notch series, it carries a Titanium Nitride (TiN) finish applied via a PVD coating process. The insert targets UNJ thread standards at 14 TPI with a right-hand cutting orientation and a 60-degree included angle. With a corner radius of 0.0112 inches and a tip-to-top height of 0.1409 inches, the geometry is suited for precision threading on harder materials. Material grades C2, C3, and C4 are within scope for this insert, making it applicable across a range of workpiece hardness levels. Machinists and tooling specialists working on CNC lathes or manual threading operations are the primary users.\u003c\/p\u003e\u003cp\u003eThis insert is used in external threading applications where UNJ thread form accuracy is required. The Top Notch series is a well-established indexable threading system, and the NJK3012R14 designation indicates the insert size (3012) and pitch (14 TPI). Typical install scenarios include production threading on aerospace, hydraulic, and industrial components where UNJ profiles are specified. The KC730 grade with TiN PVD coating provides wear resistance suited for interrupted cuts and work-hardening alloys commonly encountered in these environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e14 TPI external threading geometry for UNJ thread standard\u003c\/li\u003e\n\u003cli\u003eKC730 carbide grade with PVD-applied Titanium Nitride coating for extended tool life\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting orientation in NJK insert style\u003c\/li\u003e\n\u003cli\u003e60-degree included angle for standard unified thread form\u003c\/li\u003e\n\u003cli\u003eTop Notch series compatibility for secure, repeatable indexing\u003c\/li\u003e\n\u003cli\u003eApplicable to material grades C2, C3, and C4\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement threading insert for Top Notch series toolholders accepting NJK-style inserts with a 3012 insert size.

Power down and lock out the machine before indexing or replacing inserts. Use the correct torque wrench per the toolholder manufacturer specifications when securing the clamping screw. Inspect the insert seat and clamping components for wear or debris before seating a new insert to ensure accurate positioning and thread form output.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NJK\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: KC730\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2, C3, C4\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: 14 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: 3012\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Top Notch\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\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: 0.0112 inches (0.28 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: 0.0661 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: 1114370\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51732847395122,"sku":"1114370","price":211.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/587d7fe0371d16a54dd4eaf2a310ee77.jpg?v=1788747485","url":"https:\/\/voomisupply.com\/products\/kennametal-1114370-threading-insert-14-tpi-kc730-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
