Manufactured to Insert Style NA6R2, the insert carries the KCU10 manufacturer grade and features a Physical Vapor Deposition (PVD)-applied AlTiN finish for improved wear resistance and tool life at elevated cutting temperatures. The right-hand insert covers a 2 TPI internal pitch with an included angle of 29 degrees. A 0.0050-inch corner radius and a cutting tip width of 0.1802 inches make it well suited for precision thread-form work. Licensed machinists and CNC tooling technicians working in production or job-shop environments install this insert.\u003c\/p\u003e\u003cp\u003eThis threading insert is intended for Acme thread-form applications, both internal and external, where a right-hand cutting direction is required at 2 TPI. The Top Notch series platform accommodates the NA insert style, making this insert a direct fit for compatible Top Notch-style toolholders. Typical use cases include threading on lathes and turning centers in general machining, maintenance repair, and production environments where Acme thread forms are specified on shafts, lead screws, and similar components.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKCU10 carbide grade with PVD-applied AlTiN finish for extended tool life in threading operations\u003c\/li\u003e\n\u003cli\u003eAcme thread standard, right-hand cutting direction, 2 TPI pitch\u003c\/li\u003e\n\u003cli\u003e29-degree included angle consistent with Acme thread-form geometry\u003c\/li\u003e\n\u003cli\u003eCutting tip width of 0.1802 inches (4.58 mm) for accurate thread-form reproduction\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.0050 inches (0.13 mm) for precise tip geometry\u003c\/li\u003e\n\u003cli\u003eTop Notch series insert platform for secure, repeatable seating in compatible toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in Top Notch series toolholders that accept the NA insert style in Insert Size 6.

Power down and lock out the machine spindle before changing or indexing inserts. Use the appropriate torque wrench and clamp screw specified by the toolholder manufacturer — do not overtighten or substitute hardware. Inspect the insert seat and clamp for chips or debris before seating the insert to ensure proper contact and runout control.\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: 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: 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\u003eWidth of Cutting Tip\u003c\/strong\u003e: 0.1802 inches (4.58 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: 0.3831 inches (9.73 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Top Notch\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\u003eWeight\u003c\/strong\u003e: 0.03 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: 4176141\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51747086926130,"sku":"4176141","price":451.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a657ea79fe7eb615488aa2f5ede1de2e.jpg?v=1788875907","url":"https:\/\/voomisupply.com\/products\/kennametal-4176141-threading-insert-na6r2-kcu10-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
