It carries a Titanium Nitride (TiN) finish applied via PVD coating process and is manufactured in the KC730 grade. This insert generates partial profile 60-degree threads and handles both internal and external threading operations. It covers an external pitch range of 0.60 to 1.75 mm (14 to 44 TPI) and an internal pitch range of 1.00 to 2.00 mm (12 to 24 TPI). Machinists and CNC operators use this insert for precision thread-turning on lathes where consistent pitch accuracy and tool life are critical.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for threading operations on steel, cast iron, and non-ferrous materials falling within material grades C2, C3, and C4. It is designed for use in Top Notch series toolholders that accept the NTF insert style at insert size 2. The left-hand designation makes it appropriate for left-hand thread forms or specific machine spindle orientations. The partial profile 60-degree geometry covers a broad range of standard metric and inch thread pitches in a single insert, reducing the number of tooling changes required during a threading program.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKC730 carbide grade with PVD-applied Titanium Nitride (TiN) coating for wear resistance\u003c\/li\u003e\n  \u003cli\u003eExternal pitch range: 0.60 to 1.75 mm (14 to 44 TPI)\u003c\/li\u003e\n  \u003cli\u003eInternal pitch range: 1.00 to 2.00 mm (12 to 24 TPI)\u003c\/li\u003e\n  \u003cli\u003ePartial profile 60-degree thread form covers a wide range of metric and inch standards\u003c\/li\u003e\n  \u003cli\u003eLeft-hand insert orientation for matching left-hand thread applications\u003c\/li\u003e\n  \u003cli\u003eCorner radius of 0.08 mm (0.0031 inches) for precise thread root geometry\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in Top Notch series toolholders that accept NTF-style inserts at insert size 2.

Always power down and lock out the machine spindle before seating or removing threading inserts. Confirm insert orientation matches the toolholder pocket and verify the clamping mechanism is fully engaged before resuming operation. Do not exceed the pitch range specified for this insert, as doing so risks poor thread form and premature edge failure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NTF\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: 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: 0.60 to 1.75 mm (14 to 44 TPI)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInternal Pitch\u003c\/strong\u003e: 1.00 to 2.00 mm (12 to 24 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: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTip to Top of Insert\u003c\/strong\u003e: 2.79 mm (0.1098 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 3.81 mm (0.15 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.08 mm (0.0031 inches)\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\u003eSeries\u003c\/strong\u003e: Top Notch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0053 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: 1112942\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51728817586482,"sku":"1112942","price":183.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d2fbe2a00c2aeab9e3dec0f44afcb53c.jpg?v=1788696341","url":"https:\/\/voomisupply.com\/products\/kennametal-1112942-threading-insert-ntf2l-kc730-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
