Manufactured from carbide stock and finished with a PVD-applied TiAlN coating, this insert delivers hard, wear-resistant performance in demanding threading applications. The NA6R2 geometry is a right-hand insert with a 29-degree included angle, sized for a 2 TPI internal pitch. The insert measures 0.3831 inches thick and carries a tip-to-top dimension of 0.2831 inches. It seats into compatible Top Notch toolholders and is the type of insert a machinist or toolroom tech replaces as part of routine insert rotation in a CNC or manual lathe threading operation.\u003c\/p\u003e\u003cp\u003eThis insert is suited for shops producing Acme-threaded components in materials rated for C2 and C6 carbide grades. Typical applications include power-transmission lead screws, jack screws, and vise components machined on CNC turning centers or engine lathes. The TiAlN PVD coating makes it a practical choice for dry or semi-dry cutting conditions where heat resistance and coating adhesion are priorities. Insert size 6 corresponds to the Top Notch holder system, making toolholder compatibility a key consideration before ordering.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCarbide substrate with PVD TiAlN coating for heat and wear resistance\u003c\/li\u003e\n\u003cli\u003e29-degree included angle matches Acme thread form geometry\u003c\/li\u003e\n\u003cli\u003eRight-hand orientation, cuts internal and external threads\u003c\/li\u003e\n\u003cli\u003e2 TPI internal pitch rating for coarse Acme thread production\u003c\/li\u003e\n\u003cli\u003eTop Notch series insert size 6 for use in matching Top Notch toolholders\u003c\/li\u003e\n\u003cli\u003eWidth of cutting tip: 0.1803 inches (4.58 mm) for defined thread form accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in Top Notch series toolholders accepting insert size 6.

Ensure the machine spindle is fully stopped and the toolholder is secured in the turret before changing inserts. Inspect the insert pocket and seating surface for chips or debris before seating the new insert. Follow shop-standard tool offset and trial-cut procedures after any insert change to verify thread form and pitch before running production parts.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NA6R2\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: 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: 2 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: 6\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: 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: 0.2831 inches (7.19 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth of Cutting Tip\u003c\/strong\u003e: 0.1803 inches (4.58 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.3831 inches (9.73 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0936 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\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: 1799451\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51732937802034,"sku":"1799451","price":392.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/564977c151bab8b4039ef65517b80cee.jpg?v=1788749116","url":"https:\/\/voomisupply.com\/products\/kennametal-1799451-threading-insert-na6r2-kc5025-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
