Carrying the KC5025 manufacturer grade and a PVD-applied TiAlN coating, this right-hand insert handles a thread range of 48 to 16 TPI (0.50 to 1.50 mm pitch) and seats in toolholders sized for an 11NR insert style. The 1\/4-inch (6.35 mm) inscribed circle and 3.04 mm thickness match standard laydown pocket geometry. A CB chipbreaker geometry promotes chip control during internal threading passes on CNC lathes and turning centers. Licensed machinists and CNC operators install this insert in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for internal threading operations on CNC lathes, turning centers, and mill-turn machines where a partial profile 60-degree thread form is required. The 48-16 TPI range covers a broad span of unified and metric-equivalent thread pitches, making it a practical choice for shops threading a variety of bore diameters in steel, stainless, and other materials where TiAlN PVD coatings provide thermal and wear resistance.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKC5025 grade solid carbide with PVD TiAlN coating for wear and heat resistance during internal threading\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting, partial profile 60-degree thread form covering 48-16 TPI (0.50-1.50 mm pitch)\u003c\/li\u003e\n  \u003cli\u003e11NR insert style with 1\/4-inch (6.35 mm) inscribed circle for standard laydown toolholder compatibility\u003c\/li\u003e\n  \u003cli\u003eCB chipbreaker geometry aids chip evacuation in blind and through bores\u003c\/li\u003e\n  \u003cli\u003e3.04 mm thickness (0.1260 decimal inch) and 3.25 mm hole diameter for secure clamping in pocket\u003c\/li\u003e\n  \u003cli\u003eCorner radius of 0.05 mm (0.0020 decimal inch) for precise thread root geometry\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement for 11NR-style laydown threading insert pockets that accept a 1\/4-inch inscribed circle.

Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torque wrench and manufacturer-specified clamping hardware for the toolholder to ensure proper seating of the insert in the laydown pocket. Inspect the pocket and clamping screw for wear or debris before seating a new insert.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 11NR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC5025\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\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 Type\u003c\/strong\u003e: Internal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Partial Profile 60 Degree\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 48-16 TPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: 0.50-1.50 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 1\/4 inch (6.35 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 3.04 mm (0.1260 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.05 mm (0.0020 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 3.25 mm (0.1280 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: CB\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0046 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291804\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 1679773\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51740201812274,"sku":"1679773","price":589.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3998aa7929186e87a1b88d9024884fe7.jpg?v=1788823486","url":"https:\/\/voomisupply.com\/products\/kennametal-1679773-threading-insert-48-16-tpi-1-4-in-ic-kc5025","provider":"Voomi Supply","version":"1.0","type":"link"}
