TNMG 160404 AH6225 — Turning insert by Tungaloy, PVD‑coated carbide, 60°

TNMG160404 AH6225 is a triangular ISO turning insert designed for external and internal turning in variable production conditions

• PVD‑coated carbide grade AH6225
• ISO TNMG 160404 form with 60° cutting angle
• 0.4 mm corner radius for general turning
• Double‑sided chipbreaker with cylindrical hole

Consistent medium‑duty performance for rostfreier Stahl

The PVD‑coated carbide cutting grade AH6225 was developed for a balance of edge sharpness and robustness in medium machining. Its geometry offers a 60° approach suited to general turning tasks where surface quality and consistent tool life matter. Thanks to the combination of coating and substrate, the insert maintains a stable cutting edge under variable conditions, reducing unplanned tool changes and supporting predictable cycle times.

Easy integration into ISO tool systems

The insert follows the ISO TNMG 160404 standard, which simplifies selection for compatible holders and boring bars. Compatibility depends on form, clearance angle (0°), tolerance class, fastening, size (16 mm) and thickness (4.76 mm), and the plate comes with a cylindrical hole for secure clamping. This standardisation enables straightforward replacement and inventory management within established turning tool systems.

Improved chip control and process reliability

A double‑sided chipbreaker promotes effective chip formation and evacuation, contributing to more consistent surface finishes and lower rework rates. The PVD layer increases wear resistance and thermal stability compared with uncoated grades, extending useful life under interrupted cuts or mixed batches. For operations aiming at higher productivity, this translates into fewer tool interventions and steadier output quality.

Practical system advice for trouble‑free turning

Typical setups include the ISO insert, a suitable external holder or boring bar, and the correct shim/clamping set with spare screws. The cutting edge radius of 0.4 mm suits general turning; for heavy roughing or precision finishing, select a different radius or chipbreaker adapted to the workpiece rigidity. The insert works well for both external and internal turning when paired with a holder matched to its ISO form and dimensions.

FAQ

Which materials are best machined with this insert?
The TNMG160404 AH6225 insert is optimised for rostfreier Stahl; its PVD‑coated carbide composition also provides versatility across other medium‑duty stainless steel turning applications.

How is the insert mounted and can it be indexed?
The TNMG160404 form features a standard ISO shape with a cylindrical hole for positive clamping; the insert is double‑sided and can be indexed according to the holder’s instructions to extend usable life.

What are the key benefits of the AH6225 PVD coating?
PVD coating on the AH6225 grade increases wear resistance and thermal stability, improving tool life and surface finish consistency during medium turning operations.

How to ensure compatibility with an existing holder?
Compatibility is determined by insert form, clearance angle (0°), tolerance class, fastening method, size and thickness; check these dimensions against the holder specification before fitting the TNMG160404 AH6225 insert.
