Running the KC5025 grade with a PVD-applied TiAlN coating, this insert is engineered for right-hand external threading operations on a wide range of workpiece materials including steel, stainless steel, cast iron, superalloys, and titanium. The insert style is ER with a size code of 16, a 3\/8-inch (9.53 mm) inscribed circle, and a thickness of 0.1430 inches (3.44 mm). It is sold individually but carries a minimum order quantity of 10 units. Licensed machinists and CNC lathe operators in production and job-shop environments are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for external UN thread turning on lathes and turning centers where consistent thread form and tool life on difficult materials are required. The CB chipbreaker geometry supports chip control during threading passes on steel and stainless steel components. The TiAlN PVD coating provides heat resistance and wear resistance at elevated cutting speeds, making it a practical choice for both interrupted and continuous threading cuts in high-production runs or precision single-piece work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction with PVD TiAlN coating for wear and heat resistance\u003c\/li\u003e\n  \u003cli\u003eRight-hand external UN thread form at 8 TPI\u003c\/li\u003e\n  \u003cli\u003eER insert style, size code 16, with CB chipbreaker geometry\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch inscribed circle (9.53 mm) and 0.1430-inch thickness (3.44 mm)\u003c\/li\u003e\n  \u003cli\u003eCompatible workpiece materials: steel, stainless steel, cast iron, superalloys, and titanium\u003c\/li\u003e\n  \u003cli\u003eHole diameter of 0.1551 inches (3.94 mm) for standard insert clamping\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in lathe and turning center toolholders accepting ER-style laydown threading inserts with a size code 16 and 3\/8-inch inscribed circle.

Ensure the machine spindle is fully stopped and all motion is locked out before seating or removing the insert. Use the correct torx or hex key to secure the clamping screw to the toolholder manufacturer's specified feel  -  do not overtighten, as carbide inserts are brittle. Confirm insert orientation matches the right-hand thread cutting direction before running a threading cycle.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\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\u003eISO Code\u003c\/strong\u003e: LT16ER8UNCB\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC5025\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\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 8\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\u003eCutting Edge to Theoretical Edge Length\u003c\/strong\u003e: 0.0510 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFace of Insert to Tip Centerline\u003c\/strong\u003e: 0.0590 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\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\u003eChipbreaker\u003c\/strong\u003e: CB\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: 0.0882 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291804\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: 10\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: 1712564\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51741067444530,"sku":"1712564","price":628.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1139b77e5bb4412e0f5dcd06bb11882d.jpg?v=1788829195","url":"https:\/\/voomisupply.com\/products\/kennametal-1712564-threading-insert-8-tpi-3-8-in-kc5025","provider":"Voomi Supply","version":"1.0","type":"link"}
