Built from solid carbide and finished with a PVD-applied TiAlN\/TiN coating, this insert delivers wear resistance and thermal stability across a working pitch range of 5.50 to 10.00 mm, corresponding to 4.5 to 2.5 TPI. It carries a 60-degree included angle and a 15.88 mm inscribed circle, fitting the Snap Tap series insert system. Licensed machinists and tool-and-die professionals install this insert in CNC lathes and threading toolholders configured for internal threading applications. Manufacturer grade is CP300.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for internal threading of steel components in precision machining environments, including production turning centers and manual lathes equipped with compatible Snap Tap series toolholders. The 26NR insert style targets partial-profile internal thread forms where the thread root geometry is controlled by the workpiece bore rather than the insert tip. Typical applications include threading hydraulic fittings, valve bodies, pipe couplings, and similar steel components requiring ISO-standard thread forms at coarser pitches.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with PVD TiAlN\/TiN coating for extended tool life on steel\u003c\/li\u003e\n  \u003cli\u003eRight-hand internal partial profile, 60-degree included angle thread form\u003c\/li\u003e\n  \u003cli\u003eWorking range of 4.5 to 2.5 TPI (5.50 to 10.00 mm pitch) for coarse threading\u003c\/li\u003e\n  \u003cli\u003e15.88 mm inscribed circle with 0.3102 inch thickness for secure seating in Snap Tap holders\u003c\/li\u003e\n  \u003cli\u003eISO-standard geometry; primary workpiece material code P (steel)\u003c\/li\u003e\n  \u003cli\u003eCP300 manufacturer grade optimized for coated carbide threading performance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement insert for Snap Tap series internal threading toolholders accepting 26NR-style laydown inserts.
