Seco 00049833 Threading Insert 14 Tpi 3/8 in Ic Un Carbide

Product Description

The SECO 00049833 is a laydown threading insert designed for external UN thread cutting on CNC lathes and turning centers. Built from solid carbide in the CP500 grade with a PVD-applied TiAlN/TiN finish, this insert delivers consistent thread form and tool life across a wide range of workpiece materials. It carries a 60-degree included angle to match the UN thread standard and produces right-hand external threads at 14 threads per inch. The inscribed circle measures 3/8 inches and the insert thickness is 0.1366 inches. Licensed machinists, toolroom operators, and CNC programmers specify this insert for precision threading operations where dimensional accuracy and edge integrity are critical.

This insert is suited for external UN threading in production and job-shop environments. The CP500 carbide grade with PVD coating handles universal workpiece materials, including cast iron, non-ferrous alloys, stainless steel, and superalloys as indicated by the material codes K, M, N, P, and S. It belongs to the Snap-Tap series and is classified under ISO standards, making it a practical choice for shops that standardize on ISO-compatible tooling systems and need reliable 14 TPI UN thread output on turning equipment.

Installation Notes

Installation and indexing should be performed by a qualified machinist or toolroom technician with the machine in a fully stopped and locked-out state. Ensure the toolholder pocket and clamping screw are clean and free of chips before seating the insert. Verify insert orientation matches the right-hand cutting direction before resuming spindle operation. Follow the toolholder manufacturer's clamping torque guidance and consult applicable shop safety procedures when handling carbide inserts.
