Built from micrograin solid carbide and finished with a PVD-applied TiAlN\/TiN coating, this insert delivers sharp cutting edges and extended tool life across a broad range of workpiece materials. It belongs to the Snap Tap series and carries the CP500 grade designation. With a 3\/8-inch inscribed circle and a thickness of 0.1366 inches, the insert fits standard toolholders configured for 16ER-style laydown inserts. Licensed machinists and toolroom professionals use this insert for precision thread-forming on pipe fittings, valve bodies, and related components requiring NPTF sealing threads.\u003c\/p\u003e\u003cp\u003eThis insert is suited for external right-hand NPTF threading operations in both production and job-shop environments. The 60-degree included angle and a corner radius of 0.0020 inches support accurate thread form. The universal material grade compatibility — covering ISO material groups K, M, N, P, and S — makes it appropriate for a wide range of metals including cast iron, stainless steel, aluminum, carbon steel, and heat-resistant alloys. It is a practical choice wherever tapered pipe thread standards require a pressure-tight seal without a thread sealant compound.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide substrate for improved toughness and edge retention\u003c\/li\u003e\n\u003cli\u003ePVD TiAlN\/TiN coating provides wear resistance and thermal stability\u003c\/li\u003e\n\u003cli\u003e11.5 TPI NPTF thread form with 60-degree included angle for accurate pipe thread geometry\u003c\/li\u003e\n\u003cli\u003eRight-hand external cut for standard tapered pipe thread applications\u003c\/li\u003e\n\u003cli\u003eUniversal material compatibility across ISO groups K, M, N, P, and S\u003c\/li\u003e\n\u003cli\u003eSnap Tap series design for consistent laydown insert seating and repeatability\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-compatible replacement or production insert for 16ER-style laydown threading toolholders used in external NPTF pipe thread operations.

Ensure the machine spindle is fully stopped and the toolholder is secured in the turret before changing inserts. Inspect the insert pocket and clamping screw for wear or debris prior to seating the insert.
