Finished with a PVD-applied Titanium Nitride (TiN) coating, this insert handles a 60-degree partial profile thread standard and is configured for left-hand threads. It covers an external pitch range of 1.25 to 6.25 mm (4 to 20 TPI) and an internal pitch range of 2.00 to 6.25 mm (4 to 12 TPI). Manufactured in grade KC730, it falls within material grades C2, C3, and C4. Machinists and CNC operators working in production threading applications will find this insert suited to demanding thread-forming work.\u003c\/p\u003e\n\u003cp\u003eThis insert is used in metalworking and machining environments where precise thread profiles are required on both internal bores and external diameters. The NTP4L insert style fits Top Notch series toolholders. It is appropriate for threading operations on steel, alloy steel, and similar materials where KC730 grade carbide with a TiN coating provides wear resistance and edge stability. It is typically installed in CNC lathes or manual threading setups by machinists, tool-and-die technicians, and production shop operators.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKC730 carbide grade with PVD Titanium Nitride coating for wear and heat resistance\u003c\/li\u003e\n  \u003cli\u003eCovers external pitch range of 1.25 to 6.25 mm (4 to 20 TPI)\u003c\/li\u003e\n  \u003cli\u003eCovers internal pitch range of 2.00 to 6.25 mm (4 to 12 TPI)\u003c\/li\u003e\n  \u003cli\u003e60-degree partial profile thread form for versatile thread-cutting applications\u003c\/li\u003e\n  \u003cli\u003eLeft-hand insert configuration (NTP4L style)\u003c\/li\u003e\n  \u003cli\u003eTop Notch series insert for use with compatible Top Notch series toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Top Notch series threading toolholders that accept insert size 4 NTP-style inserts.

Confirm the insert is fully seated in the pocket and that the clamping mechanism is secure before resuming cuts. Verify left-hand orientation requirements match the threading direction of the operation before setup. Follow shop safety protocols and applicable OSHA machine guarding standards during tooling changes.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NTP4L\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\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: Left 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\u003eSeries\u003c\/strong\u003e: Top Notch\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\u003eWeight\u003c\/strong\u003e: 0.0441 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: 1112956\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51743538807090,"sku":"1112956","price":289.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1004a251e14b0640ba794ec67202dd95.jpg?v=1788848070","url":"https:\/\/voomisupply.com\/products\/kennametal-1112956-threading-insert-ntp4l-kc730-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
