Iscar 5903479 Threading Insert Un 16 Tpi IC908 Carbide

Product Description

The ISCAR 5903479 is a TTG-style carbide threading insert designed for external UN thread profiles at 16 TPI. Built to the DecaIQThread series standard, this insert uses an IC908 manufacturer grade carbide substrate with a PVD coating process for wear resistance and edge retention during threading operations. The insert is right-hand oriented and carries an ISO 13399 designation of TTG-16E-16-UN. With a cutting tip width of 0.0830 inches (2.10 mm) and a corner radius of 0.0070 inches (0.19 mm), it is suited for precision external threading on CNC lathes and turning centers.

This threading insert is intended for external UN thread applications in production machining environments. It is used on CNC turning centers and lathes where consistent thread form and tool life are critical. The IC908 grade with PVD coating performs well on a range of steels and alloys in interrupted and continuous cut threading. Installation requires a compatible TTG-style insert pocket and toolholder. Sold individually per package; minimum order quantity is 4 pieces.
