Seco 00073109 Laydown Threading Insert CP500 Carbide

Product Description

The SECO 00073109 is a solid carbide laydown threading insert designed for internal right-hand threading operations. Carrying the 22NRN60 insert style designation and manufactured to the CP500 grade, it features a TiAlN/TiN PVD coating for improved wear resistance and thermal stability during cutting. The insert profiles a 60-degree partial thread form across a 7-5 TPI range, making it well suited for threading operations where multiple thread pitches within that band are encountered. At 0.1854 inches thick with a 1/2-inch inscribed circle, this insert seats securely in compatible laydown toolholders. Sold in a minimum order quantity of 2, with a package quantity of 1 per unit.

This insert is intended for use in internal threading applications on CNC lathes and turning centers. The 60-degree partial profile thread form covers unified and metric-adjacent thread standards within the 3.50-5.00 mm pitch range (7-5 TPI). It is typically used by machinists and toolroom professionals threading bores in steel, stainless, and similar materials where a PVD-coated solid carbide insert provides adequate tool life and surface finish.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Ensure the machine spindle is fully stopped and the toolholder is secured before seating or replacing the insert. Use the correct torque wrench and clamping screw specified by the toolholder manufacturer to avoid insert rocking or seat damage. Inspect the toolholder pocket for wear or debris before installing a new insert.
