DNMG150616 AH6225 indexable turning insert by Tungaloy — PVD-coated carbide, for turning

The DNMG150616 AH6225 is an ISO‑standard rhombic indexable insert designed for external and internal turning, offering a PVD‑coated carbide grade optimised for stainless steels and variable machining conditions

• ISO rhombic turning insert DNMG form
• PVD-coated carbide AH6225 grade for stainless steel
• Double-sided chipbreaker for stable cutting
• Central hole (cylindrical) for secure clamping

Reliable cutting performance for stainless steels and variable conditions

The rhombic indexable geometry combined with the PVD-coated carbide AH6225 creates a balance between sharpness and edge robustness that is especially useful when machining stainless steels. The coating reduces built-up edge and thermal wear, while the substrate maintains strength under intermittent cutting. In practice this means more consistent surface finish and longer intervals between index changes; the design supports medium cutting parameters where both finish and tool life matter. The integrated chipbreaker promotes predictable chip formation, lowering the risk of stringing or entanglement and simplifying chip evacuation.

Secure clamping and compatibility explained for straightforward tool selection

Compatibility with a toolholder depends on several measurable characteristics — form, clearance angle (0°), tolerance class, fastening method, size and thickness — all of which determine seating and stability. The insert features a cylindrical central hole and a plate thickness of 6.35 mm, enabling positive clamping and repeatable positioning. The standardised ISO designation ensures that the component can be matched to any holder accepting the DNMG150616 form; when selecting a holder, check the corner radius 1.6 mm and the insert pocket geometry to maintain correct cutting edge projection and minimise chatter. Clear specification reduces set‑up time and supports reproducible results across machines.

Practical productivity gains and recommended application approach

Using a double‑sided insert with a corner radius of 1.6 mm and a robust grade like AH6225 yields economical use of the insert area while preserving edge integrity during varied cuts. For turning operations, start with conservative feeds and speeds aligned to the workpiece material, then increase until the desired combination of surface finish and tool life is reached; the PVD layer helps tolerate moderate increases in cutting speed. Choose the matching chipbreaker variant according to material ductility and depth of cut — the included double‑sided breaker supports a wide range of chip volumes and promotes reliable chip control, contributing to stable cycle times and reduced rework.

FAQ

What materials is this insert suitable for?
The DNMG150616 AH6225 insert is formulated for machining stainless steels and performs well under medium machining conditions thanks to its PVD‑coated carbide composition.

How does the chipbreaker benefit production?
The double‑sided chipbreaker on this indexable insert supports consistent chip formation, reducing risks of entanglement and improving evacuation in turning operations.

Which holders are compatible with the DNMG150616 form?
Holders designed for the DNMG ISO form with matching pocket geometry, correct projection and clamping for a cylindrical central hole will be compatible; ensure the holder accepts a 15 mm plate size and 6.35 mm thickness.

What is the corner radius and why is it important?
The insert has a corner radius of 1.6 mm; this radius influences surface finish and strength of the cutting edge and should be matched to the intended feed and depth of cut.

Can the insert be used for internal turning?
Yes, the rhombic shape and securing hole allow use in both external and internal turning; select an appropriate holder to ensure rigidity and clearance.
