Manufactured from solid carbide with a PVD-applied TiAlN coating, this insert cuts right-hand internal UN threads at 14 threads per inch (TPI). The KC5025 grade is engineered for threading difficult-to-machine materials, delivering consistent thread form and edge integrity across production runs. With a 3\/8-inch inscribed circle and a thickness of 0.1430 inches (3.44 mm), this insert follows the LT16NR14UN ISO designation for laydown-style toolholders. It is installed by machinist and CNC turning professionals in job shops, aerospace, and general manufacturing environments.\u003c\/p\u003e\u003cp\u003eThis insert is suited for internal UN thread cutting in materials including steel, stainless steel, cast iron, superalloys, and titanium. The laydown seating style provides rigid support in compatible LT-style toolholders, making it appropriate for both roughing and finishing thread passes on through-holes and blind bores. The 14 TPI UN thread form is a common specification in general industrial and mechanical assembly applications. Minimum order quantity is 10 units; packaging contains 1 insert per unit.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction with PVD TiAlN coating for extended tool life in abrasive and high-temperature cutting conditions\u003c\/li\u003e\n\u003cli\u003eCuts right-hand internal UN threads at 14 TPI\u003c\/li\u003e\n\u003cli\u003eKC5025 grade rated for steel, stainless steel, cast iron, superalloys, and titanium\u003c\/li\u003e\n\u003cli\u003eLaydown insert style seats securely in LT16-series toolholders for rigid, repeatable thread form\u003c\/li\u003e\n\u003cli\u003e3\/8-inch inscribed circle with 0.1430-inch thickness for standard LT16 pocket fit\u003c\/li\u003e\n\u003cli\u003ePVD coating process preserves sharp cutting edge geometry at the insert tip\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in LT16NR-style laydown threading toolholders.

Power down and lock out the machine spindle before changing inserts. Use the appropriate torque wrench and insert screw to secure the insert in the toolholder pocket — do not overtighten by hand. Inspect the insert pocket for debris or wear before seating the new insert to ensure proper contact and thread-form accuracy.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NR Laydown\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: LT16NR14UN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC5025\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid 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\u003eThread Standard\u003c\/strong\u003e: UN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal\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: 14\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: 0.1430 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: 0.0350 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFace of Insert to Tip Centerline\u003c\/strong\u003e: 0.0470 inches\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\u003eUNSPSC Code\u003c\/strong\u003e: 23291804\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0103 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 insert per package\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\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: 1743924\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51735591092530,"sku":"1743924","price":620.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/147b413d973e5b502963329bec256097.jpg?v=1788773153","url":"https:\/\/voomisupply.com\/products\/kennametal-1743924-threading-insert-14-tpi-un-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
