Built to the NAS insert style and manufactured in KENNAMETAL grade KCU10, this insert features a physical vapor deposition (PVD)-applied aluminum titanium nitride (AlTiN) finish that extends tool life in demanding cutting conditions. It carries a 6 TPI internal pitch and a 29-degree included angle, making it purpose-built for Stub Acme thread profiles. Part of the Top Notch series, the insert is sized at Insert Size 3 and configured for right-hand operation. Machinists and tool room technicians use this insert in CNC lathes and manual turning centers where consistent thread geometry and surface finish are required.\u003c\/p\u003e\u003cp\u003eThis insert is suited for threading operations on ferrous and non-ferrous workpieces in job shop, production machining, and maintenance machining environments. The right-hand configuration covers the majority of standard Stub Acme threading setups encountered in power transmission, lead screw, and actuation component manufacturing. It seats into Top Notch series toolholders designed to accept Size 3 inserts.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCarbide substrate with AlTiN finish applied via PVD process for heat and wear resistance\u003c\/li\u003e\n\u003cli\u003eNAS insert style, Size 3, compatible with Top Notch series toolholders\u003c\/li\u003e\n\u003cli\u003eCuts Stub Acme thread profile at 6 TPI with a 29-degree included angle\u003c\/li\u003e\n\u003cli\u003eRight-hand configuration for standard threading direction\u003c\/li\u003e\n\u003cli\u003eHandles both internal and external thread cutting applications\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.005 inches (0.13 mm) and cutting tip width of 0.0652 inches (1.66 mm)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Top Notch series toolholders accepting NAS-style Size 3 threading inserts.

Seat the insert fully and evenly in the toolholder pocket and torque the clamping screw according to the toolholder manufacturer specifications. Verify thread profile and pitch with a thread gauge before running production cuts. Inspect the insert seating surface and pocket for chips or debris prior to installation.\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 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\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: 6 TPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 29 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\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\u003eCorner Radius\u003c\/strong\u003e: 0.005 inches (0.13 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth of Cutting Tip\u003c\/strong\u003e: 0.0652 inches (1.66 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\u003eWeight\u003c\/strong\u003e: 0.021 pounds\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: 4176032\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51728140632370,"sku":"4176032","price":217.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6309b28acc99b6b6ae241890a35e5781_6c89d23a-1609-45a7-858f-b1e3ae55d410.jpg?v=1788688663","url":"https:\/\/voomisupply.com\/products\/kennametal-4176032-threading-insert-nas3r6-kcu10-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
