Vargus 62075 Threading Insert Un External 20 Tpi 3/8 Inch

Product Description

The VARGUS 62075 is a solid carbide, on-edge threading insert designed for external UN thread forms cut in the right-hand direction. Built to the ANSI B1.1:74 standard, this insert operates at 20 threads per inch (TPI) and features a 3/8 inch inscribed circle (IC). The micrograin carbide substrate is finished with a PVD-applied TiN coating, which extends cutting edge life across a wide range of workpiece materials. The neutral rake geometry and 10-degree rake angle support consistent thread form accuracy. This insert is used by machinists and tool-and-die professionals running CNC lathes or manual threading operations on external fastener profiles and threaded components.

This insert is suited for external threading applications across universal workpiece material categories, including ferrous metals, non-ferrous metals, stainless steels, high-temperature alloys, and plastics. Its broad material compatibility makes it a practical choice for job shops and production environments where a single insert grade needs to cover multiple material types. The insert style code is 3VER with insert size code 16, and it carries a hole diameter of 0.1516 inches and a thickness of 0.1417 inches.

Key Features

• On-edge insert style (3VER) engineered for external UN threading at 20 TPI
• Solid micrograin carbide substrate with PVD TiN coating for extended tool life
• 3/8 inch inscribed circle with neutral rake and 10-degree rake angle for consistent thread geometry
• Compatible with universal workpiece materials: ferrous, non-ferrous, stainless, high-temp alloys, and plastics
• Conforms to ANSI B1.1:74 and manufactured under ISO 9001:2008 quality standards
• Right-hand cutting direction for standard lathe threading setups

Compatibility

Designed as an OEM-style replacement threading insert for toolholders accepting the 3VER insert style in size code 16, used in external UN thread-form applications on CNC and manual lathes.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine before seating or replacing the insert. Use the appropriate torx or hex key driver specified by the toolholder manufacturer to achieve proper clamping torque without cracking the carbide substrate. Verify thread form and pitch against part print before initiating a production run.
