Manufactured from solid carbide with a PVD-applied TiAlN coating, this insert carries the KC5025 grade designation and is built to handle right-hand external threading at 16 threads per inch. The 3\/8-inch (9.53 mm) inscribed circle and 0.1430-inch thickness conform to the LT16ER16UN ISO profile, making it a direct-fit insert for compatible toolholders. Machinists and CNC operators working in production threading environments install this part for consistent thread form and long tool life across demanding workpiece materials.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for threading steel, stainless steel, cast iron, superalloys, and titanium. It performs in both roughing and finishing threading passes on external UN-profile threads at 16 TPI. The TiAlN PVD coating resists heat and wear at elevated cutting speeds, making it appropriate for higher-productivity threading cycles in job shop and production settings. The ER insert style seats in standard LT-style laydown threading toolholders designed for this insert geometry.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKC5025 carbide grade with PVD TiAlN coating for wear and heat resistance\u003c\/li\u003e\n  \u003cli\u003eRight-hand external UN thread profile at 16 TPI\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch inscribed circle (9.53 mm) in LT16ER16UN ISO profile\u003c\/li\u003e\n  \u003cli\u003eInsert thickness of 0.1430 inches (3.44 mm) for precise laydown seating\u003c\/li\u003e\n  \u003cli\u003eHole diameter of 0.1551 inches (3.94 mm) for secure clamping in compatible holders\u003c\/li\u003e\n  \u003cli\u003eCompatible workpiece materials include steel, stainless steel, cast iron, superalloys, and titanium\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in LT-style laydown threading toolholders accepting the LT16ER insert size.

Power down and lock out the machine spindle before indexing or replacing inserts. Seat the insert fully against the toolholder pocket and torque the clamping screw per the toolholder manufacturer specification. Inspect the insert seating pocket for chips or debris before installation to avoid insert rocking or premature edge failure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: LT16ER16UN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: ER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: External\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inch (9.53 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1430 inches (3.44 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1551 inches (3.94 mm)\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\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Superalloys, Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0097 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: 1724737\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51727230140722,"sku":"1724737","price":617.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a8b8ba9f5135b3f55c880cc85494d913.jpg?v=1788675052","url":"https:\/\/voomisupply.com\/products\/kennametal-1724737-threading-insert-16-tpi-3-8-in-ic-un","provider":"Voomi Supply","version":"1.0","type":"link"}
