Seco 00075894 Threading Insert 26NR 2ACME CP300 Carbide

Product Description

The SECO 00075894 is a laydown threading insert engineered for right-hand internal Acme thread cutting at 2 threads per inch (TPI). Manufactured from solid carbide in the CP300 grade with a PVD-applied TiAlN/TiN coating, this insert delivers consistent edge life and wear resistance when threading steel workpieces. The 26NR insert style features a 15.88 mm (0.6252 inch) inscribed circle and a thickness of 7.88 mm (0.3102 inches), fitting standard Snap Tap toolholders. The 29-degree included angle matches the Acme thread form precisely. This insert is intended for use by machinists and CNC lathe operators working to ISO standards.

This insert is suited for internal Acme thread production in steel components, where a 2 TPI coarse thread pitch is required. Typical applications include lead screws, power transmission components, and actuator threads machined on CNC or manual turning centers. The CP300 grade and PVD coating make it well suited to general-purpose steel cutting, including low- to medium-alloy steels classified under ISO P workpiece material. The insert is sold individually per package with a minimum order quantity of 2 pieces.

Installation Notes

Threading inserts of this type are installed by machinist or CNC turning personnel using standard insert torx or hex keys per toolholder manufacturer specifications. Always index or replace the insert with the machine in a safe, powered-down state and the spindle fully stopped. Inspect the toolholder pocket for chips or debris before seating the insert. Do not exceed the chipload or cutting parameters specified for the CP300 grade in the tool manufacturer's application data.
