It carries the KC5025 manufacturer grade with a TiAlN finish applied via PVD coating, making it well-suited for demanding threading operations where wear resistance and edge integrity are critical. The insert follows the NAS style in the Top Notch series, with a right-hand cutting orientation and an included angle of 29 degrees. At 8 threads per inch, it targets coarser Stub Acme pitches common in power-transmission and motion-control components. Machinists and CNC operators working in job shops or production environments will find this insert fits standard Top Notch toolholders.\u003c\/p\u003e\u003cp\u003eThis insert is used in turning and threading operations where Stub Acme thread profiles are required. The Stub Acme thread standard is common in lead screws, linear actuators, and similar mechanical assemblies. The insert handles both internal and external thread cutting in a single grade, reducing tooling inventory. It is sized as an Insert Size 3 and suits applications in ferrous and non-ferrous materials within the C2 and C6 material grade ranges.\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\u003c\/li\u003e\n\u003cli\u003eCuts Stub Acme thread form at 8 TPI with a 29-degree included angle\u003c\/li\u003e\n\u003cli\u003eRight-hand insert orientation for standard threading direction\u003c\/li\u003e\n\u003cli\u003eSuitable for both internal and external thread profiles\u003c\/li\u003e\n\u003cli\u003eTop Notch series for compatibility with Top Notch toolholding systems\u003c\/li\u003e\n\u003cli\u003eInsert Size 3 with a tip width of 0.0476 inches and tip-to-top height of 0.1492 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Top Notch series toolholders that accept NAS-style Size 3 threading inserts.

Power down and lock out the machine spindle before seating or removing the insert. Use the correct torque wrench and insert screw specified by the toolholder manufacturer  -  do not over-tighten, as carbide inserts are brittle and can crack under improper clamping force. Inspect the insert seat and clamp for chips or debris before each 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\u003eSeries\u003c\/strong\u003e: Top Notch\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\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\u003eThread Standard\u003c\/strong\u003e: Stub Acme\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal, 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: 8 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\u003eTip to Top of Insert\u003c\/strong\u003e: 0.1492 inches (3.79 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth of Cutting Tip\u003c\/strong\u003e: 0.0476 inches (1.21 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: 0.0207 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: 1796531\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51743326830898,"sku":"1796531","price":244.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b906eeb9f36b2c283d2d2f74ab4f113a.jpg?v=1788845678","url":"https:\/\/voomisupply.com\/products\/kennametal-1796531-threading-insert-stub-acme-8-tpi-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
