Manufactured to a KC730 grade with a PVD-applied Titanium Nitride (TiN) finish, this insert delivers consistent performance on a range of workpiece materials classified under C2, C3, and C4 material grades. The partial profile 60-degree thread form accommodates a broad pitch range, covering 0.70 to 3.00 mm (8 to 36 TPI) for external threading and 1.25 to 3.50 mm (7 to 20 TPI) for internal threading. It belongs to the Top Notch series and is intended for installation by machinists and tooling technicians on CNC lathes and turning centers.\u003c\/p\u003e\u003cp\u003eThis insert is suited for threading applications across general metalworking environments, including production shops and job shops running both ferrous and non-ferrous workpiece materials. The left-hand designation makes it the correct choice for left-hand thread forms or specific machine orientations that require reverse-direction cutting. The K chipbreaker geometry is engineered to control chip flow during threading passes, which is particularly important during internal threading where chip evacuation space is limited. The Top Notch series toolholding system provides a secure, repeatable seating platform for the insert.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKC730 carbide grade with PVD Titanium Nitride (TiN) finish for wear resistance\u003c\/li\u003e\n\u003cli\u003ePartial profile 60-degree thread form covering external pitch 0.70 to 3.00 mm (8 to 36 TPI)\u003c\/li\u003e\n\u003cli\u003eInternal pitch range of 1.25 to 3.50 mm (7 to 20 TPI)\u003c\/li\u003e\n\u003cli\u003eLeft-hand insert orientation for reverse-direction threading applications\u003c\/li\u003e\n\u003cli\u003eK chipbreaker for controlled chip evacuation on internal and external passes\u003c\/li\u003e\n\u003cli\u003eCompatible with Top Notch series toolholding system for repeatable insert indexing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Top Notch series toolholders that accept NT insert style, size 2 inserts.

Power down and lock out the machine spindle before changing or indexing any insert. Inspect the insert pocket and clamping screw for wear or debris before seating a new insert to ensure proper contact. Disposing of worn carbide inserts should follow applicable shop and local regulations for carbide tooling waste.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NT2LK\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 Range\u003c\/strong\u003e: 0.70 to 3.00 mm (8 to 36 TPI)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInternal Pitch Range\u003c\/strong\u003e: 1.25 to 3.50 mm (7 to 20 TPI)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Top Notch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: Titanium Nitride (TiN)\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: 0.0752 inches (1.91 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0039 inches (0.10 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.15 inches (3.81 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.006 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291804\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: 1112913\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51730142691634,"sku":"1112913","price":221.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ed3bb49500756e70c231982e506340e7.jpg?v=1788712487","url":"https:\/\/voomisupply.com\/products\/kennametal-1112913-threading-insert-nt2lk-kc730-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
