DNMG110402 AH6225 ISO turning insert — rhombic 55° for turning by Tungaloy

A DNMG110402 AH6225 is an ISO rhombic indexable turning insert designed for external and internal turning, optimised for stainless steels with a stable cutting edge and universal mid-range performance

• PVD-coated carbide grade AH6225 for stainless steels
• Sharp, stable cutting edge for medium-duty turning
• Rhombic DNMG shape with 55° cutting angle
• Double-sided chipbreaker with cylindrical hole

Consistent performance and extended tool life

The combination of PVD-coated carbide and the AH6225 grade targets stable wear behaviour during turning of stainless steels. The coating provides wear resistance and reduces built-up edge under variable cutting conditions; the substrate carbide maintains edge integrity. As a result, machining runs show fewer tool changes and a more predictable interval between regrinds or replacements, contributing to lower process costs and higher uptime. The design supports steady surface quality during medium-duty operations while retaining a reasonably sharp geometry suitable for mixed batch production.

Seamless integration into ISO tool systems for reliable set-up

Built to ISO dimensions, the insert’s compatibility with holders is determined by form, relief angle, tolerance, clamping and thickness — all of which are matched by standard ISO external holders and boring bars. The rhombic DNMG geometry with a 55° cutting angle offers a good balance between axial and radial cutting forces, while the 4.76 mm thickness and 0° relief ensure a rigid connection in the pocket. A cylindrical hole provides secure clamping and repeatable positioning. These characteristics simplify fixture selection and reduce set-up iteration, improving process stability across batch runs.

Controlled chips and practical handling in production environments

The double-sided chipbreaker is configured for consistent chip formation and evacuation when machining stainless steels; this reduces the risk of entanglement and helps maintain surface finish. The insert is indexable, allowing rotation to a fresh cutting edge without tool replacement, which lowers tooling cost per component. With a 0.2 mm corner radius, the geometry balances edge strength and surface finish; small radii reduce cutting forces for lighter cuts while still delivering acceptable edge durability for medium cuts. The result is efficient chip control, fewer interruptions and reproducible workpiece quality.

FAQ

What materials is the insert suited for?
The DNMG110402 AH6225 indexable turning insert from Tungaloy is optimised for stainless steels; the AH6225 grade provides a wear-resistant PVD-coated carbide suited to variable cutting conditions in turning operations (SKU TUN6947107).

Is the insert double-sided and indexable?
Yes, the insert features a double-sided chipbreaker and is indexable, allowing rotation to a fresh cutting edge to extend service life and reduce tooling costs per component.

Which holder characteristics determine compatibility with this insert?
Compatibility is governed by insert form, relief angle, tolerance class, clamping method, size and thickness — for this design, the rhombic form, 0° relief and 4.76 mm thickness are key parameters when selecting an ISO holder or boring bar.

How does the chipbreaker affect machining performance?
The double-sided chipbreaker controls chip shape and evacuation, reducing risk of chip-related interruptions and supporting consistent surface finish during stainless-steel turning.

What corner radius does the insert have and what finish can be expected?
With a 0.2 mm corner radius, the geometry offers a compromise between edge strength and finer surface finish for medium-duty cuts, enabling smoother part surfaces while maintaining acceptable tool life.
