Seco 00064423 Threading Insert 14 Tpi Nptf Solid Carbide CP500

Product Description

The SECO 00064423 is a solid carbide laydown threading insert designed for cutting internal NPTF threads at 14 threads per inch. Part of the Snap Tap series, this insert uses a 16NR style profile with a CP500 manufacturer grade and a PVD-applied TiAlN/TiN coating. The micrograin carbide substrate delivers edge stability and wear resistance across a broad range of workpiece materials. At 0.3750 inches inscribed circle and 0.1366 inches thick, the insert is sized for standard laydown toolholders used in CNC lathes and turning centers. Licensed machinists and toolroom technicians are the primary installers of this insert type.

This insert is suited for producing right-hand internal NPTF tapered pipe threads on parts machined from universal workpiece materials, including cast iron, non-ferrous metals, non-metals, steel, and high-temperature alloys corresponding to material codes K, M, N, P, and S. Typical applications include threading pipe fittings, fluid connectors, and hydraulic manifold ports in both production and job-shop environments. The 60-degree included angle and 0.0020-inch corner radius conform to the ISO standard profile for NPTF thread form generation.

Key Features

• Solid carbide micrograin substrate for edge stability and extended tool life
• CP500 grade with PVD TiAlN/TiN coating for heat and wear resistance
• Right-hand 16NR insert style cuts internal NPTF tapered pipe threads at 14 TPI
• 60-degree included angle with 0.0020-inch corner radius for accurate thread form
• 3/8-inch inscribed circle fits standard laydown threading toolholders
• ISO-standard geometry compatible with universal workpiece material classes

Compatibility

Designed as an OEM-style replacement or direct-use insert for standard 16NR-style laydown threading toolholders producing internal NPTF threads at 14 TPI. Compatible workpiece material codes include K, M, N, P, and S as specified in the product attributes.

Installation Notes

Installation is performed by a qualified machinist or CNC toolroom technician. Power down and lock out the machine spindle before seating or replacing inserts. Use the correct torx or clamp screw driver as specified by the toolholder manufacturer — do not overtighten the clamp screw. Verify thread pitch and insert orientation against the toolholder specification sheet before running the first part.
