Carrying ISO code LT16NR16UNJ, this right-hand insert cuts UNJ-standard internal threads at 16 threads per inch (TPI) with a 3\/8 inch (9.53 mm) inscribed circle and a thickness of 0.1430 inches (3.44 mm). The PVD-applied TiAlN coating delivers high heat resistance and edge wear protection during interrupted cuts and high-speed threading passes. Machining professionals and toolroom technicians select this insert for its consistent thread form accuracy and long tool life on difficult-to-machine materials.\u003c\/p\u003e\u003cp\u003eThis insert is suited for internal threading operations on steel, stainless steel, cast iron, superalloys, and titanium. It is commonly used in production turning environments where UNJ thread forms are required for aerospace, fluid-system, and high-fatigue fastener applications. The NR insert style seats in compatible LT-style laydown threading toolholders designed for 16-size inserts. Its geometry and coating make it a practical choice for both roughing and finishing passes on the thread forms listed above.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide substrate with PVD TiAlN coating for extended wear resistance at elevated cutting temperatures\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, internal UNJ thread form at 16 TPI for aerospace and high-fatigue thread applications\u003c\/li\u003e\n\u003cli\u003e3\/8 inch (9.53 mm) inscribed circle, NR insert style, size code 16\u003c\/li\u003e\n\u003cli\u003eThickness of 0.1430 inches (3.44 mm) for stable laydown seating in compatible toolholders\u003c\/li\u003e\n\u003cli\u003eHole diameter of 0.1551 inches (3.94 mm) for secure mechanical clamping\u003c\/li\u003e\n\u003cli\u003eManufacturer grade KC5025 formulated for steel, stainless steel, cast iron, superalloys, and titanium\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in LT-style laydown threading toolholders accepting size 16 NR inserts.

Seat the insert fully in the toolholder pocket and confirm the clamping screw torque is within the toolholder manufacturer's specification before starting the spindle. Inspect the insert seating surface and pocket for chips or debris before each insert change, as contamination can affect thread form accuracy. Replace the insert at the first sign of edge chipping or surface finish degradation to prevent thread form errors.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: LT16NR16UNJ\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: UNJ\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: 16 TPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NR\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: 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\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: 0.0350 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFace of Insert to Tip Centerline\u003c\/strong\u003e: 0.0430 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\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.95 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: 1817050\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51730947277106,"sku":"1817050","price":74.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f9030558114fa507a18108748aa7f7a6.jpg?v=1788725171","url":"https:\/\/voomisupply.com\/products\/kennametal-1817050-threading-insert-16-tpi-unj-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
