DNMG 150408 AH6225 rhombic ISO turning insert by Tungaloy — PVD-coated carbide, 55° geometry

The DNMG150408 AH6225 is a rhombic ISO indexable insert designed for external and internal turning applications, optimised for stainless steels and medium-duty, variable cutting conditions.

• PVD-coated carbide AH6225
• Rhombic 55° geometry
• Cylindrical hole, double-sided chipbreaker

Continuous productivity through consistent cutting performance

The PVD-coated carbide grade AH6225 delivers a reliable balance between sharpness and edge stability, which translates into steady material removal rates and fewer interruptions for insert changes. The coating reduces built-up edge and improves wear resistance, so the insert maintains a predictable cutting profile over longer cycles. For production environments that require repeatable part quality, this turning grade offers measurable advantages in process stability and surface finish.

Clear guidance on holder compatibility and mounting

Compatibility is determined by the insert's shape, clearance angle, tolerance class, attachment method, size and thickness. The rhombic 55° geometry and 0° clearance angle make the insert suitable for common DNMG holders; the presence of a cylindrical hole enables secure fastening with standard screws and clamp systems. Selecting a matching outer holder and shim set ensures correct seat and flange support, reducing vibration and promoting repeatable results.

Material and application recommendations for reliable results

Designed primarily for machining stainless steels, this indexable insert is a versatile choice for mixed-production environments where materials and cutting conditions change. The double-sided chipbreaker supports controlled chip formation, which helps keep toolpaths clear and protects workpiece integrity. For roughing and medium-finishing passes on stainless steel components, the grade offers a pragmatic compromise between tool life and cutting-edge precision.

Economical life-cycle and practical handling

The ISO-standard plate format and two usable cutting edges per side mean that the insert can be indexed multiple times before replacement, lowering tooling cost per part. The plate thickness of 4.76 mm and a corner radius of 0.8 mm contribute to rigidity under load and consistent reproducibility of contour features. For shops that value predictability and easy inventory management, the standardised geometry simplifies reordering and reduces adaptor complexity.

FAQ

What materials is this insert suitable for?
The AH6225 PVD-coated carbide insert is designed primarily for machining stainless steels and performs well in medium-duty turning operations.

How does the chipbreaker affect machining?
The double-sided chipbreaker promotes controlled chip formation and evacuation, which helps maintain surface quality and reduces the risk of chip entanglement.

Which holders are compatible with this insert?
Compatibility depends on form, clearance angle, tolerance class, attachment and thickness; matching a DNMG-capable external holder with the correct shim and screw ensures a secure fit.

What benefits does the PVD coating provide?
PVD coating enhances wear resistance and reduces edge build-up, extending useful tool life and improving consistency across varying cutting conditions.

How is the corner radius relevant to the finished part?
The 0.8 mm corner radius helps combine edge strength and surface finish; it is suitable for many medium-turning profiles where a balance of robustness and detail is required.
