The insert carries the KCU10 grade with a PVD-applied AlTiN finish, which supports elevated cutting speeds and provides wear resistance in a wide range of workpiece materials. It covers an external pitch range of 0.60 to 2.50 mm (10 to 44 TPI) and an internal pitch range of 1.00 to 2.50 mm (9 to 24 TPI), making it a versatile single insert for shops running mixed threading operations. The 60-degree partial profile geometry produces threads across multiple thread standards without requiring a dedicated insert for each pitch. Machinists and CNC operators install this insert into compatible Top Notch toolholders.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for production threading on lathes in job shops, aerospace component machining cells, and general metalworking environments. The right-hand cutting direction and NTF insert style position it for standard threading applications where a 60-degree included angle is required. The insert size 3 designation matches it to the Top Notch size 3 toolholder family. It handles both internal threading operations such as tapped bores and external threading on turned shafts and studs across the supported pitch range.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKCU10 carbide grade with PVD AlTiN finish for wear resistance at elevated cutting speeds\u003c\/li\u003e\n  \u003cli\u003e60-degree partial profile geometry covers multiple thread standards in one insert\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\u003eRight-hand cutting direction, NTF insert style\u003c\/li\u003e\n  \u003cli\u003eTop Notch series — indexes into compatible Top Notch size 3 toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Top Notch series size 3 threading toolholders that accept the NTF insert style.

The insert seats into the Top Notch toolholder pocket and is secured per the toolholder manufacturer torque guidance. Verify insert orientation and hand before resuming cutting. Handle carbide inserts carefully to avoid chipping the cutting edge prior to use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NTF\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: Right 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\u003eSeries\u003c\/strong\u003e: Top Notch\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\u003eWeight\u003c\/strong\u003e: 0.04 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\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: 4175985\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51745646936370,"sku":"4175985","price":233.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/63270584eb491a3f2a9b8ed8285d7ac4_31ed1c87-bbec-468f-96be-397372947723.jpg?v=1788864590","url":"https:\/\/voomisupply.com\/products\/kennametal-4175985-threading-insert-ntf3r-kcu10-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
