Finished with a Titanium Nitride (TiN) coating applied via PVD process, this insert delivers wear resistance and extended tool life across a range of ferrous and non-ferrous materials. It carries a KC730 manufacturer grade and falls within KENNAMETAL's Top Notch series. The insert produces a partial profile 60-degree thread form and covers an internal pitch range of 2.00 to 6.25 mm (4 to 12 TPI) and an external pitch range of 1.25 to 6.25 mm (4 to 20 TPI). It is suited for right-hand threading operations on CNC lathes and turning centers.\u003c\/p\u003e\n\u003cp\u003eThis insert is used in machining environments where consistent thread quality is required across medium to high production runs. Material grades C2, C3, and C4 make it applicable to cast iron, non-ferrous metals, and general-purpose steel threading. The NTP4R insert style fits Top Notch compatible toolholders. It is typically installed by machinists and CNC operators running turning or threading cycles on manual or automated equipment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKC730 carbide grade with PVD-applied Titanium Nitride (TiN) finish for wear resistance\u003c\/li\u003e\n  \u003cli\u003ePartial profile 60-degree thread form for internal and external threading\u003c\/li\u003e\n  \u003cli\u003eExternal pitch range: 1.25 to 6.25 mm (4 to 20 TPI)\u003c\/li\u003e\n  \u003cli\u003eInternal pitch range: 2.00 to 6.25 mm (4 to 12 TPI)\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting orientation\u003c\/li\u003e\n  \u003cli\u003eTop Notch series insert style (NTP4R) for use with compatible toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with KENNAMETAL Top Notch series compatible threading toolholders.

Ensure the toolholder seat and clamping mechanism are clean and free of debris before seating the insert. Follow the toolholder manufacturer's clamping torque guidelines and verify thread depth and form with a thread gauge after the first pass.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NTP4R\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\u003eMaterial Grade\u003c\/strong\u003e: C2, C3, C4\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 Standard\u003c\/strong\u003e: Partial Profile 60 Degree\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal and 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: 1.25 to 6.25 mm (4 to 20 TPI)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInternal Pitch\u003c\/strong\u003e: 2.00 to 6.25 mm (4 to 12 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: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTip to Top of Insert\u003c\/strong\u003e: 0.1280 inches (3.25 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0065 inches (0.17 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.2551 inches (6.48 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: 0.0443 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291804\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: 1112959\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51743084347698,"sku":"1112959","price":289.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e03a7322ff147246de22846f6401cba3.jpg?v=1788842450","url":"https:\/\/voomisupply.com\/products\/kennametal-1112959-threading-insert-ntp4r-kc730-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
