Take advantage of the combination of a CVD-coated carbide grade for extended wear resistance, precise ISO compatibility and a fine 0.4 mm nose radius for consistent surface finish. Order the VNMG insert directly via Metav Werkzeuge or ask the consultants for cutting-data recommendations.

VNMG 120404 T6215 – ISO rhombic turning insert by Tungaloy (CVD-coated carbide, TM chipbreaker)

VNMG 120404 T6215 – ISO rhombic turning insert by Tungaloy is an ISO‑standard insert designed for general turning of stainless steels under stable to lightly interrupted conditions

• CVD-coated carbide grade T6215
• Designed for stainless steel turning
• ISO rhombic insert, 35° lead angle
• Cylindrical hole for secure clamping

Extended wear life and consistent chip control for stainless steels

The combination of a CVD‑coated surface and a wear‑resistant carbide substrate in grade T6215 provides a clear advantage when machining stainless steels: improved flank wear behaviour and prolonged tool life under continuous operation. The TM chipbreaker geometry supports reliable chip formation, reducing the risk of tangled chips in long or interrupted cuts. This leads to higher process stability and fewer unplanned tool changes, which directly improves productivity and cost efficiency in production environments.

Geometry that promotes accuracy and surface quality

A rhombic insert with a 35° lead angle and a 0° clearance angle offers a well-balanced compromise between cutting force distribution and accessibility in external and internal turning. The fine 0.4 mm nose radius contributes to a superior surface finish while maintaining acceptable cutting forces for small to medium depths of cut. The ISO rhombic form ensures interchangeability across ISO‑compliant holders, enabling repeatable setups and predictable results on turning centres and lathes.

Practical guidance for selection and integration in tool systems

Compatibility with a holder is determined by the insert form, free angle, tolerance class, fixing method, size and thickness; confirming these parameters avoids setup issues. The recommended system consists of an ISO insert, an appropriate external holder or boring bar, a shim/clamp set and correct fastening screws. For typical turning tasks, select the TM chipbreaker and T6215 grade for stable to slightly interrupted stainless‑steel applications; alternatively adjust the grade and chipbreaker to match workpiece alloy and rigidity of the setup. Where higher toughness is required, consider grades optimised for interrupted cuts.

FAQ

What materials is this insert suited for?
The VNMG 120404 T6215 insert is designed primarily for machining stainless steels; the T6215 grade and CVD coating help resist abrasive wear and stabilise chip formation.

How does the TM chipbreaker affect machining?
The TM chipbreaker on the VNMG120404E‑TM promotes short, controllable chips and improves evacuation during continuous and slightly interrupted turning operations.

Which holders are compatible with this ISO insert?
Compatibility depends on insert form, free angle, tolerance class, fixing and size; the VNMG120404E‑TM fits ISO‑compliant rhombic external holders and boring bars designed for VNMG inserts.
