Consistent cutting performance for stainless steel turning

The combination of a PVD coating and a wear‑resistant carbide substrate provides an excellent compromise between edge sharpness and durability. This configuration reduces flank wear during interrupted cuts and helps maintain a repeatable tool life under changing conditions. For workshops aiming to keep cycle times stable, the AH6225 grade is formulated to handle the demands of stainless steel turning without frequent insert changes, delivering predictable removal rates and surface quality.

Better chip control and geometry that simplifies setup

The double-sided chipbreaker geometry is engineered to produce controlled chips across a range of feeds and depths of cut, which lowers the risk of built‑up edge and improves surface finish. The insert’s 0.8 mm corner radius supports fine contouring while the 60° cutting angle contributes to balanced cutting forces. For those less familiar with insert specs: a smaller corner radius enables finer detail, whereas the chipbreaker helps break and evacuate chips to protect both the workpiece and the toolholder.

Designed for straightforward compatibility and secure clamping

As an ISO standard insert, the form, relief angle, tolerance class, fixing method, size and thickness determine compatibility with holders. This insert features a cylindrical centre hole, triangular shape and a 4.76 mm thickness, so it mates with common TNMG‑style turning holders. The standardised geometry simplifies inventory management and reduces the risk of mixing incompatible parts, making it easier to select the correct holder and fastening hardware for routine production tasks.

Grade and coating advantages that support productivity

The AH6225 grade is a PVD‑coated option optimised for a broad range of stainless steels; it emphasises stable edge behaviour and broad material coverage. A hard, low‑friction coating helps resist adhesion and reduces the frequency of regrinds or insert changes. In practice, this leads to steadier component quality and can contribute to lower overall tooling costs through extended service intervals and fewer process disruptions.

FAQ

What materials is this insert suitable for?
The TNMG160408 AH6225 indexable insert is formulated primarily for stainless steel machining; the AH6225 grade provides broad coverage for various austenitic and duplex grades.

How does the 0.8 mm corner radius affect component finish?
A 0.8 mm corner radius offers a balance between fine detail and edge strength, producing good surface finish while still tolerating moderate cutting forces when using the TNMG160408 AH6225 insert.

Is the insert reversible or single-use per edge?
This is a double-sided, triangular indexable insert, so it provides multiple usable cutting edges before replacement, improving economy in serial production.

Which holder characteristics determine compatibility with this insert?
Compatibility depends on holder form, relief angle, tolerance class, fixation method, size and thickness; the TNMG160408 geometry and a cylindrical centre hole are standard for TNMG holders.
