This solid carbide insert carries a dual PVD coating of TiCrAlN and TiAlN under manufacturer grade 1125, providing wear resistance suited for threading steel, stainless, and similar ferrous materials. Key cutting geometry includes a 60-degree included angle, 14 threads per inch (TPI), a chipbreaker designation of A, and a single tooth per side configuration. The insert measures 3\/8 inches inscribed circle and 5\/32 inches thick. Installation and tool selection are handled by licensed machinists and CNC operators working to print on threading operations.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for internal UN thread-form applications on machine tools equipped with compatible CoroThread 266 toolholders. The right-hand cutting orientation suits standard internal threading passes on through-holes and blind bores where UN thread standards are specified. Typical applications include production threading on turned components in manufacturing environments. The grade 1125 with PVD coating is positioned for general-purpose threading across a range of ferrous workpiece materials at moderate to higher cutting speeds. This insert is sold individually but carries a minimum order quantity of 10 units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with dual PVD coating: TiCrAlN and TiAlN for wear resistance\u003c\/li\u003e\n  \u003cli\u003eRight-hand internal UN thread form, 14 TPI with 60-degree included angle\u003c\/li\u003e\n  \u003cli\u003eCoroThread 266 series insert style, size code 16\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch (9.53 mm) inscribed circle; 5\/32 inch (3.97 mm) thickness\u003c\/li\u003e\n  \u003cli\u003eSingle tooth per side with chipbreaker style A geometry\u003c\/li\u003e\n  \u003cli\u003eHole diameter 0.1732 inches (4.40 mm) for secure clamping in compatible holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CoroThread 266 series toolholders that accept size 16 laydown threading inserts.
