TNMG160408 AH6225 triangular indexable insert for turning — Tungaloy, PVD-coated carbide, 0° clearance

TNMG160408 AH6225 is an ISO‑standard triangular insert engineered for external and internal turning, optimised for rostfreie Stähle and medium cutting conditions

• ISO‑standard triangular insert, 16 mm size
• PVD coating for edge protection
• Double‑sided geometry for extended life
• 0° clearance, 60° included angle

Consistent cutting performance and edge life

The insert’s AH6225 grade and PVD coating deliver a balance of sharpness and toughness that supports stable cutting across variable conditions. Designed for medium machining of rostfreie Stähle, the geometry provides a controlled cutting action and predictable wear behaviour, which reduces unscheduled tool changes and improves process uptime. The combination of a defined corner radius and a reinforced cutting edge helps to maintain surface quality during turning operations while keeping the risk of chipping low.

Simple compatibility and efficient handling

As an ISO‑specified triangular insert, the part fits established holder standards when matched by form, clearance, tolerance class, fastening method, size and thickness. The triangular shape with a cylindrical hole and double‑sided chipbreaker allows economical re‑indexing and predictable seating in the toolholder. Specified dimensions such as the 16 mm size and 4.76 mm plate thickness make mechanical selection straightforward; the insert is intended to be used with a suitable external holder, clamp set and replacement screws as part of the complete system.

Better chip control and process reliability

The dual‑sided chipbreaker geometry supports consistent chip control across a range of feeds and depths of cut, which reduces interruptions and helps maintain cycle times. The carbide substrate, combined with the surface treatment, enhances edge stability under fluctuating conditions, offering repeatable results for both external and internal turning. Choosing this insert promotes a more predictable tool life and contributes to overall machining economy by lowering downtime and improving the ratio between cutting time and tool changes.

Selection advice and practical support

For practical selection, match the insert’s geometry and grade to the workpiece material and machining stability. Where holders or clamping systems vary, compatibility is determined by form, free angle, tolerance class, fastening, size and thickness. If uncertain whether this insert suits a specific application, Metav Werkzeuge provides technical guidance on grade choice and holder matching to ensure optimal performance without unnecessary trial runs.

FAQ

What materials is this insert suitable for?
The TNMG160408 AH6225 insert is optimised for rostfreie Stähle and performs well in medium cutting conditions thanks to its PVD‑coated carbide substrate.

How is compatibility with a toolholder ensured?
Compatibility depends on matching form, free angle, tolerance class, fastening, size and thickness; the insert designation TNMG160408 and ISO code 160408 guide selection for suitable holders.

Is the insert reversible or single‑use per edge?
This triangular insert features a double‑sided chipbreaker and a central hole for secure clamping, allowing re‑indexing of additional cutting edges to extend service life.

Why choose the AH6225 grade for turning?
AH6225 offers a sharp yet stable cutting edge designed for fluctuating conditions; the grade and PVD surface treatment balance wear resistance and edge strength for reliable machining.

What auxiliary components are required for use?
A compatible external holder, an underlay or clamp set and the appropriate fastening screws are required to assemble the complete tooling system for this insert.
