Vargus 50330 Threading Insert 2IR 12 Tpi Un Carbide

Product Description

The VARGUS 50330 is a solid carbide laydown threading insert in the 2IR style, engineered for cutting internal UN-standard threads at 12 threads per inch (TPI). Coated with TiAlN via a PVD process, this right-hand insert delivers wear resistance and thermal stability in demanding threading operations. The 60-degree included angle matches the UN thread form precisely, and the inscribed circle measures 1/4 inch (6.35 mm) with a thickness of approximately 0.125 inch (3.17 mm). It is used by machinists and toolroom professionals running CNC lathes or manual turning equipment.

This insert is suited for internal threading operations on ferrous and non-ferrous workpieces where UN-standard threads are required. The 2IR laydown style seats in compatible laydown boring and threading toolholders. With a single tooth per side and a right-hand cutting direction, it is a straightforward replacement for production shops running UN internal thread profiles at 12 TPI. This SKU ships individually but is subject to a minimum order quantity of 10 pieces.

Installation Notes

Threading inserts should be installed by qualified machinists following the toolholder manufacturer's torque and seating procedures. Power down and lock out the machine before changing inserts. Inspect the insert pocket and clamping screw for debris or wear before seating the new insert. Always verify thread pitch and cutting direction against the workpiece specification before beginning the threading cycle.
