Manufactured from solid carbide with a PVD-applied TiAlN coating, this insert delivers consistent thread form on a wide range of workpiece materials. The right-hand configuration suits standard external threading operations on CNC lathes and turning centers. The 16ER insert style seats in compatible laydown threading toolholders. The 60-degree included angle matches the standard UN thread profile. A 9.53 mm inscribed circle and 3.68 mm thickness (0.1449 inches) define its seating geometry. This insert is installed and indexed by machinists and CNC operators in production and maintenance turning environments.\u003c\/p\u003e\u003cp\u003eThis insert is suited for external UN threading applications across a broad range of materials, including steel, stainless steel, non-ferrous alloys, and non-metallic workpieces, consistent with its universal primary workpiece material rating. The TF series designation and PR1115 grade make it appropriate for both light and moderate threading passes on CNC turning equipment. The TiAlN coating supports performance across varying cutting speeds where heat resistance and edge integrity matter.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction with PVD TiAlN coating for heat and wear resistance\u003c\/li\u003e\n\u003cli\u003e13 TPI external UN thread standard, 60-degree included angle\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting orientation for standard external threading\u003c\/li\u003e\n\u003cli\u003e16ER insert style for laydown threading toolholder compatibility\u003c\/li\u003e\n\u003cli\u003e0.25 mm (0.0098 inch) corner radius for controlled thread root form\u003c\/li\u003e\n\u003cli\u003eUniversal workpiece material rating covering steel, stainless, non-ferrous, and non-metallic materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a laydown threading insert for use in 16ER-style threading toolholders.
