Seco 00068204 Threading Insert 7 Tpi Un Solid Carbide

Product Description

The SECO 00068204 is a laydown threading insert designed for external UN thread cutting at 7 threads per inch. It is manufactured from solid carbide in the micrograin grade and carries the CP500 manufacturer grade designation. The insert features a TiAlN/TiN PVD coating for improved wear resistance and heat performance across a broad range of workpiece materials. With a 0.5-inch inscribed circle and a 0.1854-inch thickness, this 22ER-style insert fits Snap Tap series toolholders. Right-hand orientation makes it suitable for standard external threading operations on CNC lathes and turning centers. Machinists and tool-crib technicians working in production environments will find this insert suited to general-purpose threading across ferrous and non-ferrous materials.

This insert is rated for universal primary workpiece material compatibility, covering material codes K, M, N, P, and S per ISO classification. It is suited for external UN thread form applications in both job-shop and production turning environments. The 60-degree included angle conforms to the UN thread standard, making it appropriate for inch-series threading on components requiring unified thread profiles. Installation is typically performed on a CNC lathe or manual turning center by qualified machinists or toolroom personnel.

Installation Notes

Installation should be performed by a qualified machinist with the machine powered down and the spindle locked before insert indexing or replacement. Use the appropriate torque wrench and insert screw specified for the Snap Tap toolholder to avoid over-torquing the clamp screw. Inspect the insert seat and toolholder pocket for debris or damage before seating the new insert. Follow applicable shop safety procedures and machine-specific maintenance guidelines during any tooling change.
