Designated as style LT16ER14NPTCB in grade KC5025, it produces right-hand NPT threads at 14 threads per inch (TPI). The insert is manufactured from solid carbide and coated with TiAlN via a PVD process, providing wear resistance and thermal stability during threading operations. With a 3\/8-inch inscribed circle and a thickness of 0.1430 inches (3.44 mm), this insert seats into standard LT16 laydown toolholders. It is intended for installation by machinists and toolroom technicians running CNC or manual lathes.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for external NPT threading applications across a variety of workpiece materials, including steel, stainless steel, cast iron, superalloys, and titanium. Typical use cases include threading pipe fittings, hydraulic components, and instrumentation connections to NPT standard. The chipbreaker geometry (CB) helps manage chip evacuation during threading passes. The right-hand cutting orientation makes it compatible with conventional lathe spindle rotation for external thread generation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade KC5025 solid carbide construction with PVD-applied TiAlN coating for extended tool life on ferrous and difficult-to-machine materials\u003c\/li\u003e\n  \u003cli\u003eRight-hand external NPT thread form at 14 TPI for standard pipe thread applications\u003c\/li\u003e\n  \u003cli\u003eInsert style LT16ER with 3\/8-inch inscribed circle seats in standard LT16 laydown toolholders\u003c\/li\u003e\n  \u003cli\u003eChipbreaker (CB) geometry aids chip control during threading passes\u003c\/li\u003e\n  \u003cli\u003eThickness of 0.1430 inches (3.44 mm) for consistent seating and repeatable thread form\u003c\/li\u003e\n  \u003cli\u003eHole diameter of 0.1551 inches (3.94 mm) for secure mechanical clamping\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement threading insert for LT16 laydown toolholders accepting ER-style inserts.

Power down and lock out the machine spindle before changing inserts. Seat the insert fully in the toolholder pocket and torque the clamping screw per the toolholder manufacturer specification using a calibrated torque wrench. Inspect the insert seating surface and pocket for chips or debris before clamping to prevent insert rocking and thread form error.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: LT16ER (Laydown)\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: NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: External\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 14 TPI\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: 0.0430 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\u003eChipbreaker\u003c\/strong\u003e: CB\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: 0.0095 pounds\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: 1712618\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51738025263410,"sku":"1712618","price":646.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4d1fda69f9bddb0d85ce062d54b6c2fb.jpg?v=1788795717","url":"https:\/\/voomisupply.com\/products\/kennametal-1712618-threading-insert-14-tpi-npt-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
