DNMG 150612 AH6225 – ISO indexable insert for turning, 55° – Tungaloy

A DNMG 150612 AH6225 indexable turning insert designed for ISO-compatible holders, offering a universal PVD-coated carbide grade for machining stainless steels in external and internal turning operations.

• PVD-coated carbide grade AH6225
• Optimised for stainless steels
• Sharp yet stable cutting edge
• Rhombic DNMG geometry, 55°

Consistent cutting performance for stainless-steel turning

The PVD-coated carbide grade AH6225 delivers a balance between a sharp cutting edge and edge stability, which is essential when machining stainless steels under variable conditions. The coating reduces flank wear and improves resistance to built-up edge, resulting in longer tool life and more predictable cycle times. Specified as a universal grade, the insert is suited for medium machining where a reliable compromise between surface finish and tool life is required. For practical setups, selecting the correct chipbreaker and machining parameters will directly affect productivity and component quality.

Straightforward holder compatibility and robust geometry

The rhombic DNMG form with a cutting angle of 55° and a corner radius of 1.2 mm provides a familiar geometry for many ISO turning holders. Compatibility with a selected holder is determined by form, clearance angle, tolerance class, fastening method, size and thickness; the insert’s 6.35 mm plate thickness and cylindrical hole permit secure clamping and bidirectional use. The double-sided design extends usable life per indexation and supports efficient stocking. These standard dimensions simplify integration into existing tool systems while maintaining repeatable mounting and concentricity for reliable machining results.

Process efficiency, surface quality and predictable outputs

Using a universal, PVD-coated carbide insert reduces the number of grades required in the tool cabinet and helps to standardise process windows. The AH6225 grade supports stable chip formation and consistent cutting forces, which contributes to improved surface finish and lower rework rates. For production environments, this leads to fewer machine interruptions and clearer process planning: less variability in tool life, fewer unscheduled tool changes, and a smoother production flow. The indexable design allows quick replacement, supporting lean workflows and minimising downtime.

Selection advice and application support

Choose the chipbreaker and grade to match workpiece material, depth of cut and machine stability; for heavy interrupted cuts a larger corner radius and more robust setup are advised, while finishing passes benefit from smaller radii and finer feeds. If uncertain whether this insert fits a specific application, Metav Werkzeuge provides technical advice and additional data on machinability and recommended parameters. Practical considerations such as holder rigidity, spindle power and coolant strategy will determine the final performance more than the insert alone, so pair the ISO-standard insert with a matched toolholder and clamping set for best results.

FAQ

Which operations is this insert intended for?
The DNMG150612 AH6225 indexable insert from Tungaloy is intended primarily for external and internal turning operations, offering a universal solution for medium machining of stainless steels.

How is compatibility with holders ensured?
Compatibility is achieved by matching holder form, clearance angle, tolerance class, fastening, size and thickness; the DNMG geometry and 6.35 mm thickness require an ISO-compatible turning holder with corresponding seat and clamping.

Is the insert reversible or single-sided?
This insert is double-sided with a cylindrical hole and can be indexed to use both cutting edges, extending tool life; see SKU TUN6947240 for ordering and inventory reference.

What materials is the AH6225 grade best suited to machine?
The AH6225 PVD-coated carbide grade is optimised for stainless steels; selection of chipbreaker and cutting data should be adjusted to component stability and finish requirements.

How does the corner radius affect machining results?
A 1.2 mm corner radius offers a compromise between edge strength and surface finish—larger radii improve robustness in roughing, smaller radii favour finer finishes and lower cutting forces.
