Seco 00049967 Threading Insert 8 Tpi Un Carbide CP500

Product Description

The SECO 00049967 is a solid carbide laydown threading insert designed for external UN thread cutting at 8 threads per inch. It features a CP500 manufacturer grade with a PVD-applied TiAlN/TiN finish that extends tool life across a broad range of workpiece materials. The insert follows a 16ER style geometry with a 60-degree included angle, making it purpose-built for right-hand external threading operations. With a 3/8-inch inscribed circle and a thickness of 0.1366 inches, this insert seats precisely in compatible laydown toolholders. It belongs to the Snap-Tap series and meets ISO standards for threading insert geometry.

This insert is used in CNC lathes and manual turning centers performing external UN thread operations. Its universal primary workpiece material rating covers a wide range of material classes, including cast iron, stainless steel, non-ferrous materials, and steel. It is suited for both production and job-shop threading applications where consistent thread form and insert repeatability are required. Licensed machinists and CNC programmers working in precision manufacturing, maintenance shops, and contract machining will find this insert appropriate for general-purpose external threading at 8 TPI.

Key Features

Compatibility

Designed for use with Snap-Tap series laydown threading toolholders accepting 16ER style inserts. No specific model numbers were provided in the product data.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician with the machine powered down and the spindle locked before insert indexing or replacement. Use the appropriate Torx or insert-clamp wrench to seat the insert fully against the toolholder pocket without applying excessive clamping force that could chip the carbide. Verify thread pitch and insert style match the programmed toolpath before resuming cutting operations. Inspect the insert seating pocket for chips or debris prior to each insert change to maintain positional accuracy.
