It carries the NT3LK style designation and is manufactured in the KC730 grade with a Titanium Nitride (TiN) finish applied via PVD coating. This insert produces a partial profile 60-degree thread form and is configured for left-hand cutting. External pitch range is 1.25 to 4.00 mm (6 to 20 TPI) and internal pitch range is 2.00 to 5.00 mm (5 to 12 TPI). It is installed by machinists and CNC operators on lathes and turning centers performing threading passes on ferrous and non-ferrous workpieces.\u003c\/p\u003e\u003cp\u003eThis insert is suited for threading applications on turning equipment where a left-hand partial profile 60-degree thread form is required. It handles both internal and external threading in a single insert style, making it a practical choice for shops running mixed threading jobs. Material grades C2, C3, and C4 indicate suitability across a range of general-purpose cutting conditions including steel, cast iron, and non-ferrous alloys. The K-style chipbreaker aids in chip control during threading passes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKC730 carbide grade with PVD-applied Titanium Nitride (TiN) coating for wear resistance\u003c\/li\u003e\n\u003cli\u003eLeft-hand cutting configuration for reverse-thread applications\u003c\/li\u003e\n\u003cli\u003ePartial profile 60-degree included angle covers both internal and external thread forms\u003c\/li\u003e\n\u003cli\u003eExternal pitch range: 1.25 to 4.00 mm (6 to 20 TPI)\u003c\/li\u003e\n\u003cli\u003eInternal pitch range: 2.00 to 5.00 mm (5 to 12 TPI)\u003c\/li\u003e\n\u003cli\u003eK-style chipbreaker for controlled chip evacuation during threading\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in Top Notch series threading toolholders accepting NT insert style, size 3.

Seat the insert fully in the Top Notch pocket and torque the clamping screw according to the toolholder manufacturer specifications. Inspect the insert pocket for chips or debris before seating. Left-hand inserts require confirmation of spindle direction and feed direction before initiating a threading pass.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NT3LK\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC730\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Carbide\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 4.00 mm (6 to 20 TPI)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInternal Pitch\u003c\/strong\u003e: 2.00 to 5.00 mm (5 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\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\u003eInsert Size\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip to Top of Insert\u003c\/strong\u003e: 0.098 inches (2.49 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0067 inches (0.17 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: 0.0217 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: 1112896\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51751842087218,"sku":"1112896","price":236.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a8b582afe62f22dffc547d468a82eb32.jpg?v=1788924436","url":"https:\/\/voomisupply.com\/products\/kennametal-1112896-threading-insert-nt3lk-kc730-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
