It carries the KCU10 grade designation and features an AlTiN finish applied via PVD coating, which provides thermal resistance and extended edge life in demanding turning applications. This is a left-hand insert with a partial profile 60-degree thread standard and a K-style chipbreaker. It handles external pitches from 1.25 to 4.00 mm (6 to 20 TPI) and internal pitches from 2.00 to 5.00 mm (5 to 12 TPI). Machinists and CNC turning specialists working in tool rooms, job shops, and production environments are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for threading operations on CNC lathes and manual turning centers where consistent thread form and surface finish are required. Its partial profile geometry makes it adaptable across multiple thread pitches within its rated range, reducing tooling inventory for shops running varied pitch requirements. The left-hand orientation serves applications where workpiece rotation or thread direction demands left-hand cutting geometry. It fits the Top Notch series toolholding system, which is a common platform across KENNAMETAL threading toolholders.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKCU10 carbide grade with PVD-applied AlTiN finish for thermal and wear resistance\u003c\/li\u003e\n  \u003cli\u003ePartial profile 60-degree thread form covers a range of pitches without a regrind\u003c\/li\u003e\n  \u003cli\u003eLeft-hand insert orientation for applications requiring reverse thread direction\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 passes\u003c\/li\u003e\n  \u003cli\u003eFits the Top Notch series toolholding platform\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with KENNAMETAL Top Notch series threading toolholders that accept NT insert style geometry.

Power down and lock out the machine before changing inserts. Ensure the insert pocket is clean and free of chips or burrs before seating the insert, as debris under the insert will affect thread form accuracy. Follow the toolholder manufacturer's clamping torque specifications for the Top Notch locking screw, and verify insert orientation matches the intended thread hand before resuming cutting.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NT\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: KCU10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: AlTiN\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\u003eInsert Size\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Top Notch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTip to Top of Insert\u003c\/strong\u003e: 0.0980 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.17 mm (0.0067 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.001 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291804\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: 4175980\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51744001196338,"sku":"4175980","price":206.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ec6f8025d303736261a889a82bab004d_6bacc613-be7a-4e40-9aae-2a695a0ee3f0.jpg?v=1788852702","url":"https:\/\/voomisupply.com\/products\/kennametal-4175980-threading-insert-nt3lk-kcu10-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
