Built to the NTF2L insert style in the Top Notch series, it carries a K68 manufacturer grade and a C3 material grade rating. The uncoated (bright) finish makes it well suited for applications where coating buildup tolerance is tight. This left-hand insert 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), giving machinists a wide thread-cutting window in a single insert. It is installed by CNC operators, tool-and-die machinists, and precision turning professionals.\u003c\/p\u003e\u003cp\u003eThis insert is used in threading operations on CNC lathes and manual turning centers where partial profile 60-degree thread forms are required. Its left-hand orientation makes it the correct choice for left-hand thread applications on both internal bores and external diameters. Typical use cases include production threading of fasteners, fittings, and machined components across general metalworking and tooling environments. The Top Notch series holder system is required for proper seating and clamping of this insert.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCarbide construction with uncoated (bright) finish for consistent performance on a range of workpiece materials\u003c\/li\u003e\n\u003cli\u003ePartial profile 60-degree thread standard covers both internal and external thread forms\u003c\/li\u003e\n\u003cli\u003eLeft-hand insert orientation for left-hand thread cutting applications\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\u003eCorner radius of 0.08 mm (0.0031 inches) for precise thread root geometry\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with KENNAMETAL Top Notch series threading toolholders that accept size 2 NTF-style inserts.

Use the appropriate Top Notch clamping screw and torx key as specified by the toolholder documentation  -  do not overtighten the clamping screw or use improvised tools. Confirm insert hand orientation (left-hand) matches the intended thread direction before beginning the cut. Inspect the insert seat and clamping pocket for chips or debris prior to seating the new insert.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NTF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Top Notch\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: K68\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish \/ Coating\u003c\/strong\u003e: Bright \/ Uncoated\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\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExternal Pitch Range\u003c\/strong\u003e: 0.60 to 1.75 mm (14 to 44 TPI)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInternal Pitch Range\u003c\/strong\u003e: 1.00 to 2.00 mm (12 to 24 TPI)\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\u003eCorner Radius\u003c\/strong\u003e: 0.08 mm (0.0031 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\u003eWeight\u003c\/strong\u003e: 0.0066 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: 1113499\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51739874033970,"sku":"1113499","price":197.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/71119d4d047a7e7e099fc236f8b2d98c.jpg?v=1788819910","url":"https:\/\/voomisupply.com\/products\/kennametal-1113499-threading-insert-ntf2l-k68-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
