DNMG 150608 AH6225 indexable insert for turning, 55° rhombic – Tungaloy

DNMG150608 AH6225 is an ISO-format turning insert for external and internal turning, designed for stainless steel with a balance of sharpness and edge stability

• DNMG 150608 format, 55° rhombic geometry
• PVD-coated carbide grade AH6225
• Double-sided chipbreaker, cylindrical hole
• 0° clearance angle, corner radius 0.8 mm

Consistent cutting performance with AH6225 for stainless steel

The AH6225 grade is a PVD-coated carbide developed for universal use on stainless steel where conditions vary and edge stability matters. The coating reduces built-up edge and improves wear resistance during intermittent cuts, while the substrate provides sufficient toughness for medium machining. As a result, the insert maintains a sharp yet durable cutting edge, which translates into predictable tool life and fewer machining pauses for tool changes. This stability supports higher productivity in batch production and mixed-series turning.

Geometry and clamping deliver dimensional reliability

The 55° rhombic shape and 0° clearance combine to give controlled cutting forces and accessible cutting edges for both external and internal operations. The corner radius 0.8 mm smooths chip formation and increases edge strength, reducing the risk of edge chipping under variable feeds. The cylindrical hole and standard ISO DNMG interface ensure secure seating in compatible holders, so clamping repeatability supports consistent part tolerances and surface finish without extra set-up time.

Practical system compatibility and handling benefits

As an ISO-DNMG insert, the component integrates into common turning systems: matching holders, shims and fasteners determine compatibility by form, free-angle and thickness. The 6.35 mm plate thickness and 15 mm inscribed circle mean straightforward replacement in standard tool posts. The double-sided design offers two indexed cutting edges per side, extending the number of usable edges and improving cost-efficiency per edge. Because the insert is reversible, inventory needs are reduced and machine downtime for tool changes is minimised.

Improved process security and productivity in daily use

Using the DNMG150608 AH6225 indexable insert supports a predictable machining process thanks to the combination of geometry and coating. The double-sided chipbreaker aids consistent chip control during medium-duty turning, lowering the likelihood of chip entanglement and protecting the workpiece surface. Process planners benefit from the insert’s versatility across varied stainless steel grades, enabling faster set-up times and fewer trial cuts. For operations where repeatability and surface quality are priorities, this grade offers a cost-effective compromise between edge life and cutting performance.

FAQ

What machining tasks suit this insert best?
This indexable insert is optimised for external and internal turning operations, particularly where stainless steel is processed and a balance of sharpness and edge stability is required.

How many cutting edges are available per insert?
The double-sided design provides multiple indexed edges; each side can be rotated to a fresh edge, extending usable life and improving cost-efficiency.

Is the insert compatible with common DNMG holders?
The insert follows ISO DNMG geometry; compatibility depends on holder form, free-angle, tolerance class, fastening and plate thickness—verify holder specifications against DNMG150608 AH6225 dimensions.

What benefits does the AH6225 grade offer?
AH6225 is a universal PVD-coated carbide grade for stainless steel, offering a stable cutting edge, good wear resistance and consistent performance under variable cutting conditions.

Which chip control can be expected?
The double-sided chipbreaker supports controlled chip formation during medium machining, reducing the risk of chip-related interruptions and improving surface quality.
