DNMG 110408 AH6225 Turning insert — PVD-coated carbide, 55° rhombic form (Tungaloy)

DNMG 110408 AH6225 is an ISO-format turning insert optimised for medium machining, offering a sharp yet stable cutting edge for stainless-steel applications.

• DNMG geometry for versatile external and internal turning
• PVD-coated carbide grade AH6225 for stainless steels
• 55° rhombic form with 0° clearance angle
• Cylindrical-hole design for secure clamping

Consistent cutting performance for stainless steels

The PVD-coated carbide in grade AH6225 combines a sharp cutting profile with increased edge stability, making it well suited to the demands of stainless steels under variable conditions. The surface layer produced by the PVD process improves wear resistance and helps control built-up edge formation, which extends tool life in interrupted cuts and when feed or speed fluctuate. For workshops seeking predictable cycle times and fewer insert changes, this indexable grade offers a reliable balance between edge retention and toughness.

Optimised geometry for secure clamping and stable cuts

The DNMG rhombic shape with a 55° included angle and a corner radius of 0.8 mm provides a favourable combination of approach angle and strength for medium-depth turning. The insert’s 0° clearance supports a stable contact surface and the cylindrical hole enables repeatable clamping with many common ISO-compatible holders. Because compatibility with a toolholder depends on form, clearance angle, tolerance class, fastening, size and thickness, the system approach — insert plus holder, shim and replacement screw — ensures a secure assembly and consistent cutting forces, reducing vibration and improving surface finish.

Simple integration into ISO turning systems for higher productivity

As an ISO-standard indexable insert, the DNMG 110408 variant slots into established turning systems with minimal adjustment. The double-sided chipbreaker design allows the insert to be rotated and reused, which supports economical tooling practices and reduces inventory variety. Typical setups comprise the ISO insert, a matching external holder or boring bar, a shim or clamp set and spare screws. For manufacturers prioritising throughput and reproducibility, the combination of a stable geometry and the AH6225 grade provides a pragmatic route to higher productivity and predictable process windows.

FAQ

Which materials is this insert suitable for?
The DNMG 110408 AH6225 turning insert from Tungaloy is optimised for stainless steels, designed for medium machining where a sharp, stable edge is required.

How does compatibility with holders work for this insert?
Compatibility depends on the insert form, clearance angle, tolerance class, fastening method, size and thickness; the DNMG110408 format fits standard ISO DNMG holders when matching those parameters.

What are the key dimensions and identifiers for ordering?
Key data: DNMG110408 designation, corner radius 0.8 mm, thickness 4.76 mm, angle 55°; order using SKU 6903186-Tungaloy or manufacturer SKU TUN6903186.

Is the insert indexable and reversible?
Yes — the insert is double-sided with a chipbreaker on both faces, allowing rotation and reuse to extend service life.

What coating and grade does it use and why does that matter?
The insert uses a PVD-coated cemented carbide in grade AH6225, providing a wear-resistant surface and the edge properties required for reliable stainless-steel machining.
