Part of the Top Notch series, it carries a KC5025 grade designation and a TiAlN finish applied via PVD coating. The left-hand orientation and 29-degree included angle make it specific to Stub Acme thread geometry at 12 TPI. The insert measures 0.1949 inches thick with a tip-to-top height of 0.1492 inches and a cutting tip width of 0.0327 inches. Machinists and CNC lathe operators use this insert where controlled chip formation and wear resistance are required in threading operations.\u003c\/p\u003e\u003cp\u003eThis insert fits turning centers and lathes equipped with Top Notch-compatible toolholders. It is suited for both internal threading and external threading applications, making it versatile across job-shop and production environments. The Size 3 insert format and NAS insert style indicate fitment with standard Top Notch size 3 toolholders. It is appropriate for ferrous and non-ferrous materials within the C2 and C6 material grade classifications. Stub Acme thread profiles are common in power transmission components, lead screws, and linear actuators, and this insert is intended for shops producing or reconditioning those parts.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKC5025 carbide grade with PVD-applied TiAlN coating for extended tool life in threading applications\u003c\/li\u003e\n\u003cli\u003eLeft-hand insert orientation for Stub Acme thread geometry\u003c\/li\u003e\n\u003cli\u003e29-degree included angle matched to Stub Acme thread form standard\u003c\/li\u003e\n\u003cli\u003e12 TPI internal and external thread capacity in a single insert\u003c\/li\u003e\n\u003cli\u003eSize 3 NAS-style insert body compatible with Top Notch series toolholders\u003c\/li\u003e\n\u003cli\u003eCutting tip width of 0.0327 inches and corner radius of 0.0330 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 size 3 toolholders accepting NAS-style threading inserts.

Ensure the machine spindle is fully stopped and locked out before changing inserts. Verify insert orientation and hand designation match the programmed tool path direction before starting a threading cycle. Use the correct insert pocket and clamping hardware specified for Size 3 Top Notch toolholders to ensure proper seating and repeatability.\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: KC5025\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2, C6\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: Left Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInternal Pitch\u003c\/strong\u003e: 12 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\u003eInsert Size\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip to Top of Insert\u003c\/strong\u003e: 0.1492 inches (3.79 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0330 inches (0.15 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth of Cutting Tip\u003c\/strong\u003e: 0.0327 inches (0.83 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\u003eWeight\u003c\/strong\u003e: 0.019 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: 1796525\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51739713995058,"sku":"1796525","price":245.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ce24dbf678f6c8a38e802ea348ef747f.jpg?v=1788818136","url":"https:\/\/voomisupply.com\/products\/kennametal-1796525-threading-insert-nas3l12-kc5025-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
