TaeguTec has expanded its Rhino-Turn range with the introduction of the VNGX-ST chip breaker, a double-sided, four-corner insert developed for heavy-duty turning applications. The latest addition is designed to increase productivity, extend tool life and reduce tooling costs by maximising insert utilisation.
Joining the company’s recently introduced ST chip breaker family, the VNGX-ST combines advanced chip control with the versatile VNGX platform to deliver faster machining while maintaining excellent surface finish and dimensional accuracy.
Compatible with Rhino turning holders, the insert features four indexable cutting edges, doubling the usable corners compared with conventional two-edge heavy-duty turning inserts. The result is fewer insert changes, reduced downtime and lower carbide consumption, helping manufacturers improve overall machining efficiency.
Despite its 35° rhombic geometry, typically associated with finishing operations, the VNGX-ST is capable of handling depths of cut up to 3 mm. This capability enables the insert to perform everything from finishing through to heavy roughing, reducing the need for multiple tooling changes and improving process reliability.
A high 25° rake angle lowers cutting forces, minimising vibration while allowing higher cutting parameters and improved surface quality. Reduced mechanical and thermal loading also extends tool life and enhances component accuracy by limiting tool deflection.
TaeguTec recommends the VNGX-ST for use on Swiss-type sliding-head lathes, particularly machines equipped with servo oscillation technologies such as Citizen’s LFV and Star’s HFT or SCP systems, where effective chip control is critical for precision machining.
Available in six variants with either sharp or micro-honed cutting edges, the insert is suitable for machining steel, stainless steel and more demanding alloys. PVD-coated TT9020 and TT4430 grades provide high wear resistance, making the VNGX-ST well suited to high-volume production in sectors such as medical, aerospace and automotive manufacturing.
