Seco 00049827 Laydown Threading Insert 14 Tpi Nptf CP500

Product Description

The SECO 00049827 is a laydown threading insert designed for external NPTF thread cutting at 14 threads per inch. It is manufactured from solid carbide in the CP500 grade and finished with a PVD-applied TiAlN/TiN coating for extended tool life under demanding cutting conditions. The insert features a right-hand cutting orientation and a 60-degree included angle, placing it in the Snap-Tap series. With an inscribed circle of 3/8 inches and a thickness of 0.1366 inches, it seats consistently in compatible laydown-style toolholders. Machinists and tool-and-die professionals use this insert for producing tapered pipe thread forms on CNC lathes and manual threading setups.

This insert is suited for external NPTF tapered pipe thread production across a universal range of workpiece materials, including cast iron, non-ferrous metals, non-metals, steel, and heat-resistant alloys corresponding to material codes K, M, N, P, and S per ISO classification. Typical applications include threading pipe fittings, hydraulic adapter bodies, and pressure-system components where a leak-resistant tapered thread form is required. The CP500 grade and PVD coating maintain edge integrity across both interrupted and continuous threading passes in production environments.

Key Features

• Solid carbide construction in manufacturer grade CP500 for wear resistance in universal workpiece materials
• PVD-applied TiAlN/TiN coating for thermal protection and extended edge life
• Right-hand external NPTF thread profile at 14 TPI with a 60-degree included angle
• Laydown insert style with 3/8-inch inscribed circle for stable, repeatable seating
• ISO-standard geometry; compatible with Snap-Tap series toolholders
• Corner radius of 0.0020 inches for precise thread root form

Compatibility

Designed for use in Snap-Tap series laydown threading toolholders accepting a 16ER insert style with a 3/8-inch inscribed circle. Consult toolholder documentation to confirm seat geometry before installation.

Installation Notes

Installation is performed by qualified machinists following standard CNC or manual lathe tooling procedures. Power down and lock out the machine before changing inserts. Use the correct torque wrench and clamping screw specified by the toolholder manufacturer — do not overtighten, as solid carbide inserts are brittle and can fracture under excess clamping load. Verify insert seating and thread-form alignment with a gauge before resuming production cuts.
