Built to the NJF insert style in the Top Notch series, it carries a KC730 manufacturer grade with a Titanium Nitride (TiN) finish applied via PVD coating process. The insert is configured for right-hand cutting at 16 threads per inch (TPI) with a 60-degree included angle, making it suited for UNJ thread standard applications. Carbide substrate with TiN coating provides wear resistance and edge life in continuous and interrupted threading passes on steel and cast iron workpieces.\u003c\/p\u003e\u003cp\u003eThis insert is used in external threading applications on turning centers and engine lathes in production and job-shop environments. The UNJ thread standard and 16 TPI pitch make it applicable to aerospace and general engineering components requiring controlled root radius threads. Material grades C2, C3, and C4 indicate suitability for machining carbon steel, alloy steel, cast iron, and non-ferrous materials. It is installed and changed by machinists and CNC operators in shops performing high-volume or precision threading work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKC730 carbide grade with PVD-applied Titanium Nitride (TiN) coating for extended tool life\u003c\/li\u003e\n\u003cli\u003e16 TPI external pitch with 60-degree included angle for UNJ thread profile\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting configuration, NJF insert style, Top Notch series\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.0099 inches (0.25 mm) for controlled thread root geometry\u003c\/li\u003e\n\u003cli\u003eInsert size 3010 with thickness of 0.1949 inches (4.95 mm)\u003c\/li\u003e\n\u003cli\u003eTip to top of insert dimension of 0.1409 inches (3.58 mm)\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 NJF-style inserts in external threading applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThreading inserts are installed and indexed by machinists following machine lockout and spindle-stop procedures before any insert change. Use the appropriate torx or hex key as specified by the toolholder manufacturer to seat the insert securely in the pocket. Confirm insert orientation and hand designation match the toolholder before engaging the workpiece. Inspect the insert seating pocket for chips or debris that could affect insert registration and thread accuracy.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NJF\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: 16 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: 3010\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: 0.0099 inches (0.25 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\u003eSeries\u003c\/strong\u003e: Top Notch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0201 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: 1112916\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51733286584626,"sku":"1112916","price":237.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/08f2b7bd2b12d90b1a779bb4948007d0.jpg?v=1788753592","url":"https:\/\/voomisupply.com\/products\/kennametal-1112916-threading-insert-16-tpi-kc730-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
