Seco 00076239 Laydown Threading Insert 16ER2.0ISO CP200

Product Description

The SECO 00076239 is a laydown threading insert designed for external ISO threading operations on CNC lathes and turning centers. Part of the Snap Tap series, it is manufactured from solid carbide with a PVD-applied TiAlN/TiN coating that extends tool life across a wide range of workpiece materials. The insert carries the CP200 manufacturer grade, features a 60-degree included angle, a 2.00 mm thread pitch, and a right-hand cutting orientation. At 0.1366 inches thick with a 3/8-inch inscribed circle, it seats securely in compatible laydown threading toolholders. Machinists and CNC operators working in job shops, production turning, and contract manufacturing environments are the primary installers.

This insert is rated for universal primary workpiece material compatibility, covering material codes K, M, P, and S — corresponding to cast iron, stainless steel, carbon and alloy steels, and heat-resistant superalloys. It is suited for single-point external thread turning on both production and prototype parts where ISO thread profiles are required. The 2.00 mm pitch makes it directly applicable to M-series metric fastener threads and similar ISO-standard external profiles. It is equally appropriate for light-production and high-volume turning applications where consistent thread form and finish are critical.

Key Features

• Solid carbide substrate with PVD TiAlN/TiN coating for extended wear resistance
• CP200 grade rated for universal material compatibility across cast iron, steels, stainless, and superalloys
• 2.00 mm pitch, 60-degree included angle for standard ISO external thread profiles
• Right-hand cutting orientation, laydown-style insert geometry
• 3/8-inch inscribed circle and 0.1366-inch thickness for positive, repeatable seating in Snap Tap holders
• Corner radius of 0.0110 inches for controlled thread root form

Compatibility

Designed for use in Snap Tap series laydown threading toolholders accepting 16ER-style inserts with a 3/8-inch inscribed circle. Confirmed for external ISO thread turning across workpiece material codes K, M, P, and S per ISO standards.

Installation Notes

This insert is installed and changed by machinists or CNC setup technicians — machine spindle must be stopped and the program placed in a safe state before indexing or replacing the insert. Use the appropriate Torx or hex key at the manufacturer-recommended seating torque range for threading inserts to avoid over-torquing the clamp screw. Verify insert orientation and hand before resuming cutting, as an incorrectly seated or wrong-hand insert will produce defective thread form. Inspect the toolholder pocket for chips or debris before seating the replacement insert.
