TNMG 160402 AH6225 Turning insert (TNMG160402) — 60° triangular indexable insert by Tungaloy

TNMG160402 AH6225 is an ISO-compliant triangular indexable insert designed for medium turning operations on stainless steels, offering a balanced mix of edge sharpness and wear resistance for changing machining conditions.

• PVD-coated carbide grade AH6225
• Optimised for stainless steels
• 60° triangular geometry, 0.2 mm corner radius
• Double-sided chipbreaker, cylindrical hole

Consistent performance with a universal PVD-coated grade

The PVD-coated carbide grade AH6225 is formulated as a universal solution for machining stainless steels, combining a sharp cutting edge with sufficient robustness to withstand interrupted cuts and variable feed rates. This balance reduces edge chipping and improves tool life under medium machining parameters, which in turn supports predictable cycle times and fewer tool changes. Selecting a universal grade simplifies inventory while maintaining surface quality on common stainless alloys.

Geometry and mounting that suit ISO tool systems

A 60° triangular geometry with a 0.2 mm corner radius and 4.76 mm plate thickness provides a stable contact face and good support in compatible toolholders. The insert is supplied with a cylindrical centre hole and a double-sided chipbreaker design, enabling reversible use and twice the effective cutting edges per insert. Compatibility with a holder depends on form, clearance angle, tolerance class, fixing method, size and thickness; matching those parameters ensures secure clamping and repeatable cutting performance in ISO-standardised systems.

Process benefits: chip control and surface integrity

The double-sided chipbreaker and grade pairing deliver improved chip control and a consistent surface finish during both external and internal turning. For semi-finish to medium finishing passes the combination of edge geometry and chipformer reduces built-up edge tendency on demanding stainless alloys, helping to maintain dimensional accuracy and minimise rework. The indexable format supports rapid edge changes, lowering downtime and increasing effective machine utilisation.

Practical handling and economy in daily shop use

As a reversible indexable insert, TNMG160402 AH6225 allows economical edge rotation and simple stock keeping. Correct clamping and the use of the appropriate screw and spacer ensure safe operation; inserts with a central hole require the matching screw and seat geometry. The universal grade reduces the need for multiple specialised inserts, supporting a cost-effective tooling strategy while preserving process reliability in varied turning applications.

FAQ

What materials is this insert designed for?
The TNMG160402 AH6225 insert is formulated for machining stainless steels; the PVD-coated AH6225 grade provides a compromise between edge sharpness and wear resistance for a broad range of stainless alloys.

Can the insert be used on internal contours as well as external profiles?
Yes, the triangular indexable design with a 60° geometry and a 0.2 mm corner radius supports both external and internal turning operations when paired with a suitable holder.

How many cutting edges are available per insert?
The insert is double-sided with a central hole, allowing reversible indexing and effectively providing multiple usable cutting edges before replacement.

What should be considered when choosing a compatible toolholder?
Compatibility is determined by holder form, clearance angle, tolerance class, fixing method, size and plate thickness; ensuring these parameters match the ISO TNMG160402 profile is essential for secure clamping and repeatable results.

Is the coating and grade indicated on the product?
