Kennametal 1712612 Threading Insert 32 Tpi Un Carbide

Product Description

The KENNAMETAL 1712612 is a laydown threading insert designed for external UN thread forms on CNC lathes and turning centers. Manufactured from solid carbide in the KC5025 grade with a PVD-applied TiAlN coating, this insert handles right-hand external threading at 32 threads per inch. The LT16ER32UNCB ISO code identifies the ER insert style with a CB chipbreaker geometry. Carbide construction with a TiAlN finish provides wear resistance and thermal stability during threading operations. The insert seats in standard LT16 laydown toolholders and is suited for machinists and CNC operators running production threading cycles.

This insert is applied in threading operations on steel, stainless steel, cast iron, superalloys, and titanium workpieces. The right-hand cutting orientation and external thread configuration make it a direct fit for external UN 32 TPI threading passes in job shop, production machining, and aerospace component work. It is packaged as a single insert and must be ordered in multiples of 10 to meet minimum order requirements.

Installation Notes

Installation and indexing of threading inserts should be performed by a qualified CNC machinist or toolroom technician. Ensure the machine spindle is fully stopped and the toolholder is secure before seating or replacing the insert. Use a torx or hex key of the correct size for the insert clamp screw and do not overtighten. Verify thread form and pitch against the workpiece drawing before running the first threading pass.
