Running the NTK3L insert style in the KCU10 grade with a PVD-applied AlTiN finish, this insert handles partial profile 60-degree thread forms on a left-hand cutting orientation. External pitch range covers 0.60 to 2.50 mm and 10 to 44 TPI. Internal pitch range covers 1.00 to 2.50 mm and 9 to 24 TPI. It belongs to the Top Notch series and is sized as an Insert Size 3. Machinists and CNC operators use this insert on lathes and turning centers for precision threading of ferrous and hard materials where AlTiN coating improves heat and wear resistance.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for threading applications in manufacturing, production machining, and maintenance environments. It applies to both internal threading operations such as tapped bores and external threading operations such as fastener profiles and threaded shafts. The 60-degree included angle covers the most common unified and metric thread forms. Left-hand orientation makes it appropriate for left-hand thread production or specific toolholder configurations that require LH inserts within the Top Notch tooling system.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCarbide substrate with PVD AlTiN finish for elevated heat resistance and extended tool life\u003c\/li\u003e\n  \u003cli\u003eCovers external pitch range of 0.60 to 2.50 mm and 10 to 44 TPI\u003c\/li\u003e\n  \u003cli\u003eCovers internal pitch range of 1.00 to 2.50 mm and 9 to 24 TPI\u003c\/li\u003e\n  \u003cli\u003ePartial profile 60-degree thread form suits the widest range of unified and metric thread standards\u003c\/li\u003e\n  \u003cli\u003eLeft-hand insert style NTK3L for use with compatible left-hand Top Notch toolholders\u003c\/li\u003e\n  \u003cli\u003eCorner radius of 0.08 mm (0.0031 inches) for precise thread root geometry\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with compatible KENNAMETAL Top Notch series toolholders that accept Insert Size 3 left-hand threading inserts.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and the turret is in a safe indexed position before seating or removing the insert. Use the correct Top Notch clamp and torque the clamp screw per the toolholder manufacturer specification. Verify insert seating and clearance before resuming cutting operations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NTK3L\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: 0.60 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\u003eCorner Radius\u003c\/strong\u003e: 0.08 mm (0.0031 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTip to Top of Insert\u003c\/strong\u003e: 0.1409 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 4.95 mm (0.195 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Top Notch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.024 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: 4175986\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51732265238834,"sku":"4175986","price":238.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a636faaa16176bd498adc0d4bb3a3caf_1bc0416e-c2d9-46fa-b362-fe60b5e4446c.jpg?v=1788740994","url":"https:\/\/voomisupply.com\/products\/kennametal-4175986-threading-insert-ntk3l-kcu10-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
