Manufactured to the NAS style in insert size 3, it carries a KCU10 grade designation and an AlTiN finish applied via PVD coating. The AlTiN coating improves wear resistance and thermal stability during high-speed threading operations. With a 29-degree included angle and 10 TPI internal pitch, this insert is suited to Stub Acme thread generation in production and maintenance machining environments. Installation and operation are performed by machinists and CNC tooling specialists working with compatible Top Notch toolholders.\u003c\/p\u003e\u003cp\u003eThis insert is intended for Stub Acme threading applications on lathes and turning centers equipped with Top Notch series toolholding systems. It handles both internal and external thread profiles in a right-hand cutting orientation. Typical use cases include lead screw manufacturing, repair threading, and production runs where consistent Acme thread geometry is required. The PVD-applied AlTiN coating makes this insert a strong candidate for dry or semi-dry cutting conditions and harder workpiece materials where heat generation is a concern.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction with KCU10 grade for wear resistance in threading applications\u003c\/li\u003e\n\u003cli\u003eAlTiN finish applied by PVD process for thermal stability and extended tool life\u003c\/li\u003e\n\u003cli\u003eNAS style, size 3 insert fits Top Notch series toolholders\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting orientation for Stub Acme thread profiles\u003c\/li\u003e\n\u003cli\u003eCovers both internal and external thread forms at 10 TPI with a 29-degree included angle\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.005 inches (0.13 mm) 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 toolholding systems that accept NAS style size 3 threading inserts.

Power down the machine and engage all safety locks before changing or seating inserts. Inspect the toolholder pocket for chips or damage before seating a new insert, and verify secure clamping torque per the toolholder manufacturer's specification before resuming cuts. Do not exceed the cutting parameters recommended for the KCU10 grade and AlTiN coating combination.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NAS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid 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: Stub Acme\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\u003eInternal Pitch\u003c\/strong\u003e: 10 TPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 29 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Top Notch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth of Cutting Tip\u003c\/strong\u003e: 0.3700 inches (0.94 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0050 inches (0.13 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1949 inches (4.95 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip to Top of Insert\u003c\/strong\u003e: 0.1492 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 9.5 inches (L) x 2.8 inches (W) x 1.5 inches (H)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.021 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\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: 4176030\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51727515255090,"sku":"4176030","price":251.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6309b28acc99b6b6ae241890a35e5781.jpg?v=1788678774","url":"https:\/\/voomisupply.com\/products\/kennametal-4176030-threading-insert-size-3-kcu10-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
