Carrying the ISO code LT16ER18UNCB, this insert features an ER-style profile, a KC5025 manufacturer grade, and a PVD-applied TiAlN coating that supports extended tool life in demanding cutting environments. With a 3\/8 inch inscribed circle and a thickness of 0.1430 inches (3.44 mm), it delivers consistent thread geometry on right-hand external applications. Machinists and CNC programmers working in production threading operations specify this insert for its tight tolerances and reliable coating adhesion on challenging workpiece materials.\u003c\/p\u003e\u003cp\u003eThis insert is intended for right-hand external UN threading on materials including steel, stainless steel, cast iron, superalloys, and titanium. It is well suited for CNC lathes and turning centers where repeatable thread form accuracy is required. The CB chipbreaker geometry helps manage chip flow during threading passes, reducing the risk of chip interference in the cut zone. Typical applications include threaded component manufacturing in aerospace, energy, and general industrial machining where material hardness and thermal resistance are primary concerns.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction with PVD TiAlN coating for thermal and wear resistance\u003c\/li\u003e\n\u003cli\u003eER insert style with CB chipbreaker for controlled chip evacuation\u003c\/li\u003e\n\u003cli\u003e18 TPI right-hand external UN thread form\u003c\/li\u003e\n\u003cli\u003eKC5025 grade optimized for steel, stainless steel, cast iron, superalloys, and titanium\u003c\/li\u003e\n\u003cli\u003e3\/8 inch inscribed circle with 0.1430 inch thickness for consistent seating\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\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard-fit threading insert for toolholders accepting LT16-style laydown threading inserts with ER geometry.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or CNC tooling technicians. Always index or replace inserts with the machine in a safe, powered-down or locked-out state per facility lockout\/tagout procedures. Seat the insert fully against the pocket locating surfaces before tightening the clamping screw to the toolholder manufacturer specification. Inspect the insert pocket for chips or debris before seating to avoid insert rocking or premature edge failure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: LT16ER18UNCB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC5025\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\u003eInsert Material\u003c\/strong\u003e: Carbide\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\u003eChipbreaker\u003c\/strong\u003e: CB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: External\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UN\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: 18\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: 0.0280 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFace of Insert to Tip Centerline\u003c\/strong\u003e: 0.0310 inches\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: 0.0112 pounds\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: 1712604\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51743401181490,"sku":"1712604","price":533.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4f0fc7b0dd62ed12aa20387b9e37c43b.jpg?v=1788846671","url":"https:\/\/voomisupply.com\/products\/kennametal-1712604-threading-insert-18-tpi-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
