TNMG 160412 AH6225 triangular turning insert — Tungaloy, PVD-coated carbide, 60°

TNMG160412 AH6225 Tungaloy turning insert for medium turning of stainless steels and general turning tasks, designed for ISO-compatible holders and stable chip control

• TNMG 160412 geometry, 60° included angle
• PVD-coated carbide AH6225 for stainless steels
• 1.2 mm corner radius for a robust cutting edge
• Double-sided insert with cylindrical hole for secure clamping

Consistent performance for stainless-steel turning

The insert offers a PVD coating on a carbide substrate (grade AH6225), engineered for reliable edge stability during medium-duty machining of stainless steels. The combination of coating and substrate reduces flank wear and improves resistance against built-up edge, which translates into more consistent surface finish and fewer tool changes. As an ISO-format turning insert, it fits established toolholders when form, clearance angle, tolerance class, fixing method, size and thickness match, so integration into existing tooling systems is straightforward and predictable.

Designed to deliver reproducible cutting and service life

A 1.2 mm corner radius and a 60° triangular geometry balance cutting strength and versatility: the edge supports interrupted cuts and variable engagement while still permitting fine finishing passes where required. The double-sided chipbreaker and reversible design allow indexation to a fresh edge, extending usable life per insert. Choosing the correct chipbreaker and grade for the workpiece and machining parameters maximises productivity and reduces overall tooling cost by lowering the frequency of insert replacement.

Practical system compatibility and operational benefits

The ISO-series construction means the insert functions as part of a system: an appropriate external holder or boring bar, a matching shim/clamping set and replacement screws complete the assembly. The cylindrical hole ensures secure clamping and simple changeover, while the 4.76 mm thickness and 16 mm size provide stability for common turning tasks. For mixed-production environments where stainless steels are frequent, this insert offers a balance of wear resistance and edge sharpness that supports both roughing and finishing operations when cutting data are adapted to material and machine rigidity.

FAQ

What materials is this insert best suited to?
The TNMG160412 AH6225 insert is formulated for stainless steels and performs well in environments where a sharp but stable edge is required.

How does the coating improve performance?
The PVD coating on the AH6225 grade increases wear resistance and reduces adhesion, supporting longer cutting intervals and more consistent surface quality with this Tungaloy indexable insert.

Is the insert indexable and reversible?
Yes, the triangular geometry is double-sided and reversible; both sides can be indexed to present a fresh cutting edge when needed.

Which parameters determine holder compatibility?
Compatibility depends on plate form, clearance angle, tolerance class, fixing method, size and thickness; matching these ensures the insert seats and clamps securely in the chosen holder.

What benefits does the 1.2 mm corner radius provide?
A 1.2 mm corner radius improves edge strength for interrupted cuts and variable engagement while still allowing acceptable surface finish for medium machining tasks.
