Seco 00050209 Threading Insert 16ERG60 CP500 14-8 Tpi

Product Description

The SECO 00050209 is a laydown threading insert designed for external thread-cutting operations on CNC turning centers and manual lathes. Built to the 16ER insert style, this solid carbide insert carries the CP500 manufacturer grade and features a PVD-applied TiAlN/TiN coating for extended tool life across a wide range of workpiece materials. It cuts a partial profile 60-degree thread form, covering a TPI range of 14 to 8 (equivalent to 1.75 to 3.00 mm pitch), making it suitable for both inch-series and metric threading applications. The inscribed circle measures 3/8 inches and the insert thickness is 0.1366 inches.

This insert is part of the SECO Snap-Tap series and is rated for universal primary workpiece material compatibility, including workpiece material codes K, M, P, and S — covering cast iron, stainless steel, carbon and alloy steel, and high-temperature alloys. It is intended for right-hand external threading and is a practical choice for shops that need a single insert to handle a broad pitch range in production or job-shop turning environments. The insert conforms to ISO standards and carries UNSPSC code 23291804.

Compatibility

Designed for use in 16ER-compatible laydown threading toolholders. The partial profile 60-degree geometry supports both Unified (UN) and ISO metric thread forms within the 14-8 TPI (1.75-3.00 mm pitch) range. Compatible with workpiece materials classified under ISO codes K, M, P, and S.

Installation Notes

Installation is performed by machinists or CNC tooling technicians. Power down or stop spindle rotation completely before indexing or replacing the insert. Seat the insert firmly in the toolholder pocket and verify torque on the clamping screw per the toolholder manufacturer specification. Confirm thread pitch and TPI selection against the part drawing before initiating a threading pass.
