Vargus 13371 Turning Insert Cngp 432FN-EXK V25K

Product Description

The VARGUS 13371 is a CNGP-style carbide turning insert in grade V25K, designed for precision external and internal turning operations on CNC and manual lathes. The CNGP geometry features an 80-degree diamond (rhombic) shape with a neutral clearance angle and a ground tolerance profile, making it well suited for finishing and semi-finishing passes. The FN-EXK chipbreaker geometry helps control chip formation and evacuation across a range of depths of cut and feed rates. This insert is manufactured in solid carbide and is intended for use by machinists and toolroom technicians working in production or job-shop turning environments.

The VARGUS 13371 is used in turning applications where dimensional consistency and surface finish quality are priorities. The V25K grade is formulated for cutting steel and other P-category workpiece materials, including carbon steels, alloy steels, and cast steels. This insert fits standard CNGP 432 toolholders and is appropriate for both CNC machining centers with live tooling and dedicated turning centers. It is a per-piece unit sold in multiples of ten, making it practical for production floor replenishment and tool-crib stocking.

Key Features

• CNGP insert style with 80-degree diamond shape for versatile turning geometry
• V25K carbide grade optimized for steel and P-category workpiece materials
• FN-EXK chipbreaker design promotes controlled chip formation during finishing and semi-finishing
• Ground tolerance (G) for tight dimensional accuracy and consistent seating in the toolholder
• Neutral clearance angle (N) compatible with standard CNGP 432 toolholder systems
• Solid carbide construction for wear resistance in continuous and interrupted cut profiles

Compatibility

Designed as an OEM-style replacement insert for standard CNGP 432 toolholders used in CNC and manual turning applications.

Installation Notes

Carbide turning inserts are installed and serviced by machinists or toolroom technicians. Always power down and lock out the machine spindle before indexing or replacing an insert. Use the correct torque wrench and manufacturer-specified clamping hardware when seating the insert to ensure proper contact with the toolholder pocket. Inspect the pocket and clamping screw for wear or debris before installing a new insert, as a contaminated or damaged pocket will affect cutting performance and tool life.
