Seco 00064507 Threading Insert 18 Tpi Internal Un CP500

Product Description

The SECO 00064507 is a laydown threading insert designed for internal UN thread cutting at 18 threads per inch. Built from solid carbide in the CP500 grade, it features a TiAlN/TiN PVD coating that extends tool life across a broad range of workpiece materials. The insert follows the 16NR style geometry with a right-hand cutting orientation and a 60-degree included angle. With a 3/8-inch inscribed circle and a thickness of 0.1366 inches, it fits standard laydown threading toolholders used in CNC turning centers and manual lathes. Machinists and tool-and-die professionals install this insert for high-precision internal thread production.

This insert is suited for internal threading operations on materials classified under universal workpiece material codes K, M, N, P, and S, covering cast iron, stainless steel, non-ferrous metals, steel, and heat-resistant superalloys. The Snap-Tap series geometry is optimized for producing clean UN-standard thread profiles in bore and through-hole applications. It is appropriate for both production machining environments and job-shop turning work where consistent thread form and insert-to-insert repeatability are required.

Installation Notes

Installation is performed by machining professionals familiar with CNC turning or manual lathe tooling. Power down and lock out the machine before seating or replacing the insert. Use the appropriate torx or hex key as specified by the toolholder manufacturer to secure the insert clamp to the recommended clamping torque. Inspect the insert pocket for debris or damage before installation to ensure proper seating and thread form accuracy.
