Widia 3607824 Threading Insert Size 3 Nt-k TN6025 Carbide

Product Description

The WIDIA 3607824 is a carbide threading insert designed for precision thread-cutting operations on CNC lathes and turning centers. Built to the NT-K style with a TN6025 grade carbide substrate, it features an AlTiN finish applied via PVD coating process for improved wear resistance and thermal stability at the cutting edge. The insert handles both internal and external threading applications, covering an external pitch range of 1.25 to 4.0 and an internal pitch range of 2.0 to 5.0. The 60-degree V thread standard makes it suitable for unified and metric V-form thread profiles. A corner radius of 0.0065 decimal inch (0.17 mm) delivers consistent thread form geometry.

This insert is suited for production and job-shop environments where right-hand threading on a range of materials is required. It fits clamp-style toolholders that accept NT-K series inserts. The K chipbreaker geometry is intended for controlled chip evacuation during threading passes. Typical applications include threading on steel, stainless, and similar workpiece materials in both internal and external configurations. The AlTiN PVD coating supports higher cutting speeds and extended tool life compared to uncoated carbide inserts.

Compatibility

Designed for use in NT-K series clamp-style threading toolholders accepting size 3 inserts. ANSI and ISO code NT3RK. Verify toolholder specifications before installation.

Installation Notes

Threading inserts should be installed by a qualified machinist or tooling technician. Power down and lock out the machine spindle before seating or replacing the insert. Use the appropriate torque wrench and clamping screw for the toolholder to secure the insert without cracking the carbide substrate. Inspect the insert pocket for debris or damage before installing a new insert.
