Vargus 53671 Threading Insert 56 Tpi Un Solid Carbide

Product Description

The VARGUS 53671 is a solid carbide laydown threading insert designed for external UN thread cutting at 56 threads per inch. It carries a TiAlN coating applied via PVD process, delivering heat and wear resistance across a wide range of workpiece materials. The insert follows the 3ER style with a 9.53 mm inscribed circle, a thickness of 3.60 mm, and a 60-degree included angle. It is intended for use on CNC lathes and threading machines by machinists and toolroom technicians working to ANSI B1.1:74 thread standards.

This insert is suited for right-hand external UN threading operations in both production and job-shop environments. Its universal material compatibility rating covers ferrous, non-ferrous, and exotic alloy workpieces, making it a practical single-insert choice for shops threading a variety of stock. The 3ER insert style fits standard 3ER-series toolholders. Typical applications include threading bolts, studs, shafts, and other externally threaded components to UN specifications.
