VCMT 160402 AH6225 ISO turning insert for turning – Tungaloy

A VCMT 160402 AH6225 is an ISO indexable turning insert designed for external and internal turning, optimised for medium machining of stainless steels with a TM chipbreaker.

• PVD-coated AH6225 for stainless steels
• TM chipbreaker for medium cutting conditions
• 0.2 mm corner radius for versatile profiles
• ISO rhombic insert 16 mm with secure hole

Stable cutting performance for variable stainless-steel work

The insert combines a PVD-coated cemented carbide grade with a geometry tuned for stability in mixed conditions. The AH6225 grade is formulated to provide a sharp yet durable cutting edge, which reduces edge breakdown during interrupted cuts and varying feed rates. Improved edge retention and thermal resistance from the coating translate into fewer insert changes and increased machine uptime, supporting a steady production flow.

Defined geometry that controls chip formation and clamping

A rhombic form with a nominal size of 16 mm and a 0.2 mm corner radius balances profile definition and edge strength, allowing medium-depth passes while avoiding premature chipping. The 7° clearance angle reduces flank rubbing and helps maintain surface finish, while the 35° approach supports cutting stability. The insert features a cylindrical hole with a single-side countersink (40°–60°) for secure clamp engagement; compatibility with a given holder depends on form, clearance angle, tolerance class, clamp type, size and thickness, as it is part of an ISO indexable insert system.

Broad applicability and practical advice for process optimisation

Engineered for both external and internal turning, the TM chipbreaker provides controlled chip formation for many stainless-steel machining scenarios; selection of chipbreaker and cutting data should be matched to material, fixture rigidity and machining strategy. For tailored cutting parameters, holder selection or bespoke recommendations for a specific workpiece, Metav Werkzeuge’s technical team can provide application data and holder compatibility guidance to maximise productivity and tool life.

FAQ

What materials is this insert best suited for?
The VCMT160402-TM AH6225 insert is optimised for stainless steels; the AH6225 PVD-coated cemented carbide offers improved wear resistance and edge stability for these materials.

Which applications are typical for this insert?
Typical applications include both external and internal turning operations where medium cutting conditions and reliable chip control are required; the TM chipbreaker supports controlled chip formation.

How does the 0.2 mm corner radius affect performance?
A 0.2 mm corner radius provides a compromise between profile accuracy and edge robustness, reducing the risk of chipping on interrupted cuts while allowing acceptable surface finish.

How can compatibility with a toolholder be ensured?
Holder compatibility depends on insert form, clearance angle, tolerance class, clamping method, size and thickness; Metav Werkzeuge can advise on matching holders and clamping sets for secure installation.
