Vargus 51922 Laydown Threading Insert 8 Tpi Un

Product Description

The VARGUS 51922 is a solid carbide laydown threading insert designed for external UN thread cutting at 8 threads per inch. It carries a TiN coating applied via PVD process, which improves surface hardness and wear resistance across a wide range of workpiece materials. The insert follows a 3ER style profile with a 60-degree included angle, an inscribed circle of 3/8 inch (9.53 millimeters), and a thickness of 3.6 millimeters. Right-hand orientation is standard. This insert is sized and configured for use in CNC lathes and turning centers, and is typically installed by machinists and toolroom technicians performing precision thread turning operations.

The 51922 is suited for external UN threading applications in production and job-shop environments. Its universal workpiece material classification covers a broad range of metals, including carbon steels, stainless steels, cast irons, non-ferrous alloys, high-temperature alloys, and titanium. The 3ER insert style fits compatible laydown threading toolholders used on CNC turning equipment. This insert is manufactured to ANSI B1.1:74 thread standards and produced under an ISO 9001:2008 quality management system.

Installation Notes

Threading inserts of this type are installed and replaced by machinists or toolroom technicians. Power down and lock out the machine before indexing or replacing any insert. Seat the insert firmly and evenly in the toolholder pocket and secure with the appropriate clamping screw to manufacturer torque specification using a calibrated torque driver. Verify insert orientation and thread profile before resuming cutting operations.
