DNMG150404 AH6235 – Indexable turning insert for stainless steel, 55° rhombic geometry (Tungaloy)

The DNMG150404 AH6235 is a PVD-coated carbide indexable insert for turning operations, designed for machining stainless steels and interrupted cuts with a focus on stable chip control and tool life.

*PVD-coated carbide AH6235 grade *Optimised for stainless steel and interrupted cuts *Rhombic 55° geometry with 0.4 mm nose radius

Reliable performance for demanding stainless-steel turning

The combination of a PVD-coated carbide substrate and the tougher AH6235 grade delivers consistent performance when machining stainless steels or other adhesion-prone alloys. The insert’s rhombic 55° geometry and 0.4 mm nose radius are designed to balance cutting edge strength and profile accuracy, helping to maintain dimensional stability during external and internal turning. For shops seeking predictable tool life under interrupted cutting conditions, this insert provides a technically sound choice that emphasises process stability and repeatability.

Secure seating and ISO compatibility for flexible tool set-up

Compatibility with a wide range of ISO holders is determined by geometry, clearance angle, tolerance class, fixing method, size and thickness; the insert’s 0° clearance (relief angle) and cylindrical hole allow secure clamping in standard toolholders and boring bars. This simplifies tool changeover in mixed-production environments and reduces set-up time. The standardised ISO designation ensures easy identification in tooling systems and supports efficient inventory management for production planning.

Chip control and edge security reduce scrap and downtime

Equipped with a double-sided chipbreaker, the insert improves chip formation and evacuation during variable cutting conditions, which is particularly relevant when machining stainless steels that tend to produce long, gummy chips. The tougher grade and PVD coating help resist flank and crater wear while providing enhanced resistance to edge chipping in interrupted cuts. The result is fewer unscheduled tool changes, lower scrap rates and more consistent surface finishes on turned components.

Practical selection advice and process considerations

When specifying an insert of this type, select the chipbreaker and grade to match the material, machining method and machine stability; a tougher grade such as AH6235 is preferable for interrupted cuts and workpieces with higher breakout risk. Ensure holder geometry matches the DNMG150404 form and that clamping hardware conforms to the insert’s dimensions (15 mm inscribed circle, 4.76 mm thickness). Monitoring cutting parameters and adjusting feeds and speeds conservatively at the start helps confirm optimal settings without overloading the cutting edge.

FAQ

What materials is this insert best suited for?
The DNMG150404 AH6235 insert is intended primarily for stainless steels and other materials where a tougher grade and good chip control are required; the AH6235 PVD coating supports adhesion resistance in such applications.

Can the DNMG150404 be used for internal turning as well as external turning?
Yes, the DNMG150404 indexable insert is suitable for both external and internal turning when paired with a compatible holder; confirm holder geometry and clamping for secure seating and correct relief.

How does the AH6235 grade affect tool life in interrupted cuts?
The AH6235 grade provides enhanced toughness compared with standard grades, which improves resistance to chipping during interrupted cutting and helps maintain tool life under variable engagement.

Which chipbreaker should be selected for mixed production?
For mixed production including stainless steels and interrupted cuts, the supplied double-sided chipbreaker offers a versatile solution; choose the chipbreaker variant that matches the feed range and surface finish requirements.

What should be checked before installing this insert in a holder?
Verify holder compatibility with the DNMG150404 form, the 55° rhombic geometry, 0° clearance and the 15 mm inscribed circle; ensure correct clamping hardware and tolerance class for secure attachment.
