DNMG 110404 AH6225 — Indexable turning insert (ISO 110404) | Tungaloy

DNMG110404 AH6225 is an ISO-standard indexable insert for turning, engineered for medium machining of stainless steels with a stable, sharp cutting edge and a double-sided chipbreaker.

• PVD-coated carbide for stainless steels
• Rhombic form with 55° approach angle
• Double-sided chipbreaker for economical use
• Cylindrical hole for secure clamping

Reliable edge and material versatility

The PVD-coated carbide of the grade AH6225 combines a keen cutting edge with sufficient edge stability for medium-duty turning of stainless steels. This balance reduces the risk of edge chipping under varying conditions and supports consistent surface quality. The combination of coating and substrate provides improved wear resistance compared with uncoated grades, which translates into longer intervals between insert changes and lower overall tooling expenditure.

Cost-efficient handling through a double-sided design

Designed as a double-sided indexable insert, the DNMG110404 offers two usable cutting edges, effectively doubling life per insert versus single-sided alternatives. The indexable insert geometry and the rhombic form with a 55° approach angle allow efficient reach into shoulder and profile turns while maintaining rigidity. For workshops aiming to improve uptime, this geometry supports fast, repeatable index changes and straightforward inventory management.

Predictable results through system compatibility

Compatibility with turning holders is determined by form, clearance angle, tolerance class, fastening method, size and thickness. The ISO-standard designation means the insert aligns with established holder interfaces, but correct pairing is essential: choosing a holder with the matching clamp or screw, a suitable shim or seat and an appropriate tolerance class ensures stable clamping and consistent cutting conditions. Stable assembly reduces vibration, improves tool life and yields reproducible part tolerances.

Choosing the right chipbreaker and grade for the job

The double-sided chipbreaker on this insert is tailored to interrupt chips reliably in a variety of cut depths and feeds commonly encountered in stainless-steel turning. Selecting the correct chipbreaker style and the AH6225 grade for the specific alloy and cutting conditions will optimise chip control, surface finish and tool life. When process stability or material grade is uncertain, refer to the model series guidance or consult technical advisors for the best match between insert, holder and machining parameters.

FAQ

What materials is this insert best suited to machine?
The DNMG110404 AH6225 indexable insert is optimised for machining stainless steels; the AH6225 grade delivers a balance of sharpness and edge stability for medium turning tasks.

How is the insert mounted in a holder?
Mounting uses the insert’s cylindrical hole with the appropriate clamp or screw and a matching seat or shim; ensure the holder matches the ISO form, size and thickness for correct fit.

How does the chipbreaker affect performance?
The double-sided chipbreaker on the insert improves chip control across a range of feeds and depths, aiding surface finish and reducing the risk of long, entangling chips in turning operations.

Can the insert be used for both external and internal turning?
Yes; the rhombic 55° geometry and compact dimensions allow the insert to be applied to both external and internal turning when holder geometry permits.

How many usable cutting edges does the insert provide?
As a double-sided indexable insert, the DNMG110404 AH6225 provides two usable cutting edges per insert, enabling economical edge changes.
