Manufactured to the NTF insert style with a KC850 grade substrate and a CVD-applied TiC\/TiCN\/TiN multilayer finish, this insert delivers wear resistance and thermal stability across a broad range of workpiece materials. It covers external pitches from 0.60 to 2.50 mm (10 to 44 TPI) and internal pitches from 1.00 to 2.50 mm (9 to 24 TPI), making it a versatile choice for partial profile 60-degree threading. The left-hand configuration suits specific toolholder orientations in production threading applications.\u003c\/p\u003e\n\u003cp\u003eThis insert is used in precision threading operations on metal workpieces in manufacturing, tool and die, and production machining environments. It is intended for use with compatible Top Notch series toolholders. The 60-degree partial profile geometry accommodates a range of thread standards without requiring a dedicated insert for each pitch, reducing insert inventory requirements. Machinists and CNC operators working with both metric and inch-based thread specifications will find this insert applicable across common threading tasks in ferrous and non-ferrous materials rated for C5 and C6 material grades.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKC850 carbide grade with CVD-applied TiC\/TiCN\/TiN finish for extended tool life\u003c\/li\u003e\n  \u003cli\u003ePartial profile 60-degree thread form covers a wide pitch range without pitch-specific tooling\u003c\/li\u003e\n  \u003cli\u003eExternal pitch range: 0.60 to 2.50 mm (10 to 44 TPI)\u003c\/li\u003e\n  \u003cli\u003eInternal pitch range: 1.00 to 2.50 mm (9 to 24 TPI)\u003c\/li\u003e\n  \u003cli\u003eLeft-hand insert hand for dedicated left-hand threading setups\u003c\/li\u003e\n  \u003cli\u003eTop Notch series compatibility ensures secure, repeatable seating in matched 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 size 3 NTF-style inserts.

Power down and lock out the machine spindle before seating or removing inserts. Use the appropriate torx or insert-clamping tool specified for the Top Notch toolholder to ensure proper clamping torque and seating. Verify insert hand orientation matches the toolholder before beginning a threading pass to avoid thread form errors or insert damage.\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\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: KC850\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C5, C6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: TiC\/TiCN\/TiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\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 2.50 mm (10 to 44 TPI)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInternal Pitch\u003c\/strong\u003e: 1.00 to 2.50 mm (9 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: 3\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: 0.0031 inches (0.08 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\u003eWeight\u003c\/strong\u003e: 0.0225 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: 1113805\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51749798478130,"sku":"1113805","price":244.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e63be4d9cafd63d9ced2d7f9d3372c91.jpg?v=1788910614","url":"https:\/\/voomisupply.com\/products\/kennametal-1113805-threading-insert-ntf3l-kc850-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
