Kennametal 1712554 Threading Insert Iso Right Hand KC5025

Product Description

The KENNAMETAL 1712554 is a solid carbide laydown threading insert designed for internal ISO thread cutting on CNC lathes and turning centers. It carries the KC5025 grade designation and features a PVD-applied TiAlN coating for wear resistance and thermal stability during threading operations. The right-hand configuration and CB chipbreaker geometry make it suited for consistent chip control on internal thread forms. The insert has a 3/8 inch (9.53 mm) inscribed circle and a thickness of 0.1430 inches (3.44 mm), fitting standard LT16 style toolholders. This insert is installed and qualified by CNC machinists and turning specialists in precision machining environments.

The 1712554 is used in internal threading applications following the ISO thread standard with a 2.00 mm pitch. It is intended for use in production and job-shop environments where consistent thread quality and tool life are critical. The right-hand cutting geometry suits typical internal bore threading passes on compatible LT16NR toolholders. This insert is appropriate for ferrous and non-ferrous materials in residential and industrial component machining where tight thread tolerances are required.

Installation Notes

Installation should be performed by a qualified CNC machinist or toolroom technician. Ensure the machine spindle is fully stopped and the toolholder is clear of the workpiece before indexing or replacing the insert. Use the correct torque wrench and clamping screw specified by the toolholder manufacturer to seat the insert properly. Verify thread pitch and hand orientation match the programmed threading cycle before resuming operation.
