Built to Top Notch series specifications, it features an AlTiN finish applied via PVD coating process, which supports wear resistance in demanding machining environments. The insert carries a 60-degree partial profile thread form and a KCU10 manufacturer grade. With an external pitch range of 0.70 to 3.00 mm (8 to 36 TPI) and an internal pitch range of 1.25 to 3.50 mm (7 to 20 TPI), it covers a broad range of threading applications. This insert is intended for installation by machinists and CNC operators working on lathes and turning centers.\u003c\/p\u003e\u003cp\u003eThis threading insert is suited for production and job-shop environments where consistent thread form and tool life are priorities. It handles both internal and external threading in a left-hand orientation, making it appropriate for reverse-thread applications on turning equipment. The AlTiN PVD coating provides thermal stability and is well matched to ferrous and hardened materials. The Top Notch series tooling system is a common platform in production turning setups requiring quick insert indexing.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCarbide substrate with AlTiN PVD finish for extended tool life in ferrous materials\u003c\/li\u003e\n\u003cli\u003ePartial profile 60-degree thread form covers a wide TPI range without a dedicated insert per pitch\u003c\/li\u003e\n\u003cli\u003eExternal pitch range: 0.70 to 3.00 mm (8 to 36 TPI)\u003c\/li\u003e\n\u003cli\u003eInternal pitch range: 1.25 to 3.50 mm (7 to 20 TPI)\u003c\/li\u003e\n\u003cli\u003eLeft-hand insert orientation for reverse-thread turning applications\u003c\/li\u003e\n\u003cli\u003eTop Notch series platform for reliable seating and repeatable indexing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in Top Notch series threading toolholders that accept NT size 2 inserts with a left-hand configuration.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThreading inserts of this type are installed and indexed by qualified machinists or CNC tooling technicians. Ensure the machine spindle is fully stopped and all motion is locked out before changing inserts. Use the appropriate torx or clamping screw driver specified for the Top Notch toolholder to seat the insert firmly without over-torquing the clamp screw. Verify insert orientation and thread hand match the programmed toolpath before resuming cutting operations.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NT2L\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCU10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\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: 0.70 to 3.00 mm (8 to 36 TPI)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInternal Pitch\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\u003eInsert Size\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.1 mm (0.0039 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\u003eTip to Top of Insert\u003c\/strong\u003e: 0.0752 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Top Notch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 9.6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 5.2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 1.7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.007 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: 4175909\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51748399481138,"sku":"4175909","price":221.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3b211a01cbfd49ee807e602e34450328.jpg?v=1788893293","url":"https:\/\/voomisupply.com\/products\/kennametal-4175909-threading-insert-nt2l-kcu10-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
