Carrying the ISO code LT16ER24UNJ, it runs at 24 threads per inch with a right-hand cutting orientation. The insert is manufactured from carbide and coated with TiAlN via a PVD process, which delivers elevated heat resistance and extended edge life when threading challenging materials. At 0.143 inches thick with a 3\/8-inch inscribed circle, it seats securely in compatible ER-style laydown toolholders. This insert is selected and installed by CNC machinists and tool-room technicians in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for threading steel, stainless steel, cast iron, superalloys, and titanium workpieces. The UNJ thread standard specifies a controlled root radius on external threads, making this insert the correct choice for aerospace and high-fatigue applications where UNJ geometry is called out on the print. It is a single insert per package unit with a minimum order quantity of 10 pieces, consistent with production-floor tooling procurement.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTiAlN PVD coating for high heat resistance and extended tool life in ferrous and exotic alloys\u003c\/li\u003e\n  \u003cli\u003e24 TPI UNJ external thread form with right-hand cutting direction\u003c\/li\u003e\n  \u003cli\u003eSolid carbide substrate in KC5025 manufacturer grade for toughness and wear resistance\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch inscribed circle in ER insert style for stable seating in laydown toolholders\u003c\/li\u003e\n  \u003cli\u003e0.143-inch insert thickness with 0.1551-inch hole diameter for positive clamping\u003c\/li\u003e\n  \u003cli\u003eCompatible with primary workpiece materials including 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 ER-style laydown threading toolholders accepting a size 16 insert with a 3\/8-inch inscribed circle.

Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torque wrench and clamping screw specified by the toolholder manufacturer to secure the insert without cracking the carbide substrate. Confirm thread-form geometry and TPI against the part print before initiating 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 Laydown\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: LT16ER24UNJ\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: UNJ\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: External\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 24\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inches (9.53 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.143 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: 0.0270 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\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\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Superalloys, Titanium\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  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0106 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: 1743736\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51734539141426,"sku":"1743736","price":620.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4bbbb358ba907faa2926cd682907b760.jpg?v=1788763414","url":"https:\/\/voomisupply.com\/products\/kennametal-1743736-laydown-threading-insert-24-tpi-unj","provider":"Voomi Supply","version":"1.0","type":"link"}
