It carries the NTF3L insert style designation and is manufactured to the KCU10 grade with a PVD-applied AlTiN finish. The insert covers a partial profile 60-degree thread standard and handles external pitches from 0.60 to 2.50 mm (10 to 44 TPI) and internal pitches from 1.00 to 2.50 mm (9 to 24 TPI). It is a left-hand insert suited for machinists and toolroom operators working with CNC lathes or manual turning centers where thread-form accuracy is critical.\u003c\/p\u003e\u003cp\u003eThis insert is used in precision threading operations across metalworking environments, including production machining shops, maintenance and repair facilities, and job shops. Its partial profile 60-degree geometry makes it appropriate for cutting unified and metric threads on a range of workpiece materials. The AlTiN PVD coating supports dry or near-dry cutting conditions and extends tool life when threading ferrous and hardened materials. It fits into compatible Top Notch threading toolholders designed for size 3 inserts.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCarbide substrate with PVD AlTiN finish for extended wear resistance in ferrous threading\u003c\/li\u003e\n\u003cli\u003ePartial profile 60-degree thread standard covers both unified and metric thread forms\u003c\/li\u003e\n\u003cli\u003eExternal pitch range: 0.60 to 2.50 mm (10 to 44 TPI)\u003c\/li\u003e\n\u003cli\u003eInternal pitch range: 1.00 to 2.50 mm (9 to 24 TPI)\u003c\/li\u003e\n\u003cli\u003eLeft-hand insert orientation for left-hand thread cutting operations\u003c\/li\u003e\n\u003cli\u003eInsert size 3 with a corner radius of 0.08 mm (0.0031 inches) for precise thread root geometry\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Top Notch series threading toolholders accepting size 3 NTF-style inserts for internal and external threading applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following the toolholder manufacturer's clamping procedure for Top Notch inserts. Ensure the machine spindle is fully stopped and the toolholder is secure before seating or removing the insert. Verify correct insert orientation for left-hand threading before engaging the cut. Consult the toolholder documentation for recommended clamping torque and seating confirmation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NTF3L\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 Range\u003c\/strong\u003e: 0.60 to 2.50 mm (10 to 44 TPI)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInternal Pitch Range\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\u003eThickness\u003c\/strong\u003e: 4.95 mm (0.195 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 9.6 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 5.2 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1.7 mm\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\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: 4175984\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51738476806450,"sku":"4175984","price":231.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/326d421776f005a6f30d33c91693a5f6.jpg?v=1788800041","url":"https:\/\/voomisupply.com\/products\/kennametal-4175984-threading-insert-ntf3l-kcu10-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
