Seco 00731890 Threading Insert 8 Tpi Api Round Solid Carbide

Product Description

The SECO 00731890 is a laydown threading insert designed for internal API Round thread cutting at 8 threads per inch (TPI). Built from solid carbide in the CP300 grade, it features a TiAlN/TiN PVD coating applied through physical vapor deposition, which extends tool life when cutting steel workpieces. The insert follows the 27NR style with a 15.88 mm (0.6252 inch) inscribed circle and a thickness of 6.15 mm (0.2421 inch). It carries a 60-degree included angle and is configured for right-hand internal threading operations. Licensed machinists and CNC tooling technicians install this insert into compatible Snap Tap series toolholders.

This insert is suited for internal API Round thread profiles, commonly encountered in oil and gas pipe and coupling applications where API threading standards are required. With a primary workpiece material designation of P (Steel), it is engineered for ferrous machining environments. The 8 TPI pitch and right-hand configuration make it appropriate for producing standard API Round internal threads in production or maintenance machining settings. It conforms to ISO standards and is packaged individually, with a minimum order quantity of 2 units.

Compatibility

Designed for use in SECO Snap Tap series toolholders accepting the 27NR insert style. Verify toolholder pocket specifications before installation to confirm proper seating and clamping.

Installation Notes

Installation should be performed by qualified CNC machinists or tooling technicians. Ensure the machine spindle is fully stopped and locked out before changing inserts. Seat the insert fully into the pocket and torque the clamping screw per the toolholder manufacturer's specification. Inspect the insert seating and cutting edge condition before resuming operation.
