Seco 00064422 Threading Insert 14 Tpi Npt Carbide CP500

Product Description

The SECO 00064422 is a laydown threading insert designed for internal NPT thread cutting at 14 threads per inch. Built from solid carbide in the CP500 grade, it features a PVD-applied TiAlN/TiN coating for wear resistance across a wide range of workpiece materials. The insert follows a 16NR geometry with a 3/8 inch inscribed circle and measures 0.1366 inches thick. It is engineered for right-hand internal threading operations and suits CNC lathes and turning centers equipped with compatible toolholders. Licensed machinists and CNC operators install these inserts in production threading applications.

This insert is suited for threading NPT pipe connections in both production and job-shop environments. The 60-degree included angle and 14 TPI specification make it appropriate for standard NPT taper pipe thread profiles. The CP500 carbide grade with PVD coating supports universal workpiece compatibility, including ferrous, non-ferrous, and stainless materials. It is part of the Snap-Tap series, which is intended for laydown-style threadmill and threading insert holders used on CNC turning equipment.

Compatibility

Designed as a replacement or production-run insert for Snap-Tap series laydown threading toolholders that accept the 16NR insert style. No specific toolholder model numbers were provided in the product data.

Installation Notes

Insert seating and clamping should be performed with the machine powered down and the spindle locked. Use the torque specifications provided by the toolholder manufacturer when securing the clamp screw. Verify insert orientation for right-hand internal cutting before engaging the workpiece. Inspect the insert seat for chips or debris before each insert change to prevent premature edge failure.
