Consistent productivity for stainless-steel turning

The combination of a PVD-coated surface and the AH6225 carbide formulation delivers an excellent balance between a sharp cutting edge and robust edge stability. This results in steady cutting forces and reduced flank wear during medium-duty operations on stainless steels, which in turn supports predictable tool life and fewer interruptions for index changes. The 0.8 mm corner radius improves edge strength while maintaining surface finish, meaning one insert can cover a wider range of passes without compromising quality.

Secure fit and simple integration with ISO holders

Compatibility depends on form, clearance angle, tolerance class, attachment type, size and thickness. The ISO-standard TNMG geometry and a cylindrical hole ensure reliable seating in matching external holders or boring bars; the 0° clearance facilitates consistent contact geometry and repeatable clamping. Translating these specs into practice: match the insert’s triangular form and thickness to the holder’s pocket and fastening screw to avoid run-out and to maintain concentricity for tight tolerances.

Improved chip control and predictable machining behaviour

The double-sided chipbreaker is engineered for reliable chip formation across varying feeds and depths of cut, reducing the risk of entanglement and machine downtime. For users less familiar with chipbreakers: this is a small groove or contour on the insert’s rake face that influences how chips curl and break. With the TNMG geometry and AH6225 coating, the insert supports stable cutting in variable conditions, helping to increase process reliability and reduce scrap rates.

FAQ

What materials is this insert optimised for?
The TNMG 110408 AH6225 is optimised for stainless steels, with the AH6225 grade offering a mix of sharpness and edge stability for medium machining.

How does the PVD coating benefit performance?
The PVD-coated surface on this turning insert reduces adhesion, improves wear resistance and helps maintain a sharp edge under fluctuating cutting conditions.

Can the insert be used in standard TNMG toolholders?
Yes; the ISO-standard TNMG geometry and the cylindrical hole make the insert compatible with matching TNMG holders when the pocket, fastening and tolerance class are correctly selected.

What does the double-sided chipbreaker mean in practice?
A double-sided chipbreaker provides chip control on both indexable faces, enabling the insert to be turned over and reused, which extends service life and offers flexibility for varying feeds.

Which dimensional values should be matched when selecting a holder?
Match the triangular form, 11 mm plate size, 4.76 mm thickness, corner radius and the cylindrical-hole fastening to ensure correct seating and repeatable clamping with TNMG holders.
