Seco 00067911 Threading Insert 5 Tpi Un Solid Carbide CP500

Product Description

The SECO 00067911 is a laydown-style threading insert designed for external UN thread forms at 5 threads per inch. Manufactured from solid carbide in the CP500 grade, this insert features a PVD-applied TiAlN/TiN coating for wear resistance and extended tool life across a wide range of workpiece materials. The 22ER insert style with a 60-degree included angle is engineered for right-hand external threading operations on CNC lathes and turning centers. At 0.1854 inches thick with a 0.5-inch inscribed circle, it seats securely in compatible 22ER toolholders. Machinists and toolroom technicians install this insert in production threading applications where consistent thread geometry and repeatable surface finish are required.

This insert suits general-purpose external threading across multiple material categories including cast iron, stainless steel, non-ferrous alloys, high-temperature alloys, and steel. The universal material compatibility rating covers workpiece material codes K, M, N, P, and S per ISO classification. It is well suited for both production turning environments and job-shop operations requiring a single threading insert grade capable of handling varied material types. The Snap Tap series design supports quick indexing to minimize downtime during high-volume threading runs.

Key Features

• Solid carbide construction in CP500 grade for rigidity and edge stability
• PVD TiAlN/TiN coating for improved wear resistance and thermal protection
• 5 TPI right-hand external UN thread form with 60-degree included angle
• ISO-compliant 22ER insert style with 0.5-inch inscribed circle
• Universal workpiece material compatibility across ISO codes K, M, N, P, and S
• Snap Tap series design for fast, repeatable indexing

Compatibility

Designed for use in 22ER-compatible external threading toolholders. Suitable for right-hand external UN thread applications at 5 TPI. Verify toolholder pocket geometry and clamping style against the 22ER insert specification before installation.

Installation Notes

Installation is performed by qualified machinists or CNC toolroom personnel. Power down and lock out the machine spindle before indexing or replacing inserts. Ensure the toolholder pocket is clean and free of chips before seating the insert, as debris under the insert will affect thread geometry. Handle solid carbide inserts carefully to avoid chipping the cutting edge prior to use.
