The insert features a 60-degree included angle and a TiN (titanium nitride) coating applied via PVD process, which helps extend tool life across a broad range of workpiece materials. With an inscribed circle of 9.53 mm (3\/8 inch) and a thickness of 3.60 mm, this is a right-hand, single-tooth insert in the standard series. It is used by machinists and CNC operators producing precision UNJ-standard internal threads in aerospace, defense, and general machining applications.\u003c\/p\u003e\n\u003cp\u003eThe VARGUS 52406 is suited for internal threading operations on a wide range of workpiece materials, including aluminum, cast iron, stainless steel, non-ferrous metals, steel, and high-temperature alloys, corresponding to material codes H, K, M, N, P, and S. The UNJ thread standard, governed by MIL-S-8879C, is commonly specified in aerospace and military fastener applications where thread root radius is critical. This insert fits standard laydown toolholders accepting the 3IR insert style.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in demanding threading operations\u003c\/li\u003e\n  \u003cli\u003eTiN coating via PVD process for extended tool life and reduced built-up edge\u003c\/li\u003e\n  \u003cli\u003eRight-hand internal thread cutting at 12 TPI with a 60-degree included angle\u003c\/li\u003e\n  \u003cli\u003eUNJ thread form compliant with MIL-S-8879C and ISO 9001:2008 quality standard\u003c\/li\u003e\n  \u003cli\u003eUniversal workpiece material compatibility across six material groups (H, K, M, N, P, S)\u003c\/li\u003e\n  \u003cli\u003eInscribed circle of 9.53 mm (3\/8 inch) in the standard 3IR laydown insert format\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard laydown toolholders accepting the 3IR insert style for internal right-hand threading at 12 TPI to the UNJ thread standard.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or CNC programmers. Power down and lock out the machine before seating or replacing the insert. Use the appropriate torx or insert-clamping wrench specified by the toolholder manufacturer to secure the insert  -  do not overtighten by hand or with unapproved tools.
