DNMG150416 AH6225 Tungaloy indexable insert — ISO DNMG 150416, PVD-coated carbide for turning

DNMG150416 AH6225 Tungaloy is an ISO‑standard indexable insert for external and internal turning, engineered for medium machining of stainless steels and variable workshop conditions

• ISO DNMG 150416 geometry for stable turning
• PVD-coated carbide grade AH6225 for stainless steels
• 1.6 mm corner radius for medium roughing and finishing
• Rhombic insert with cylindrical hole, double-sided chipbreaker

Long-lasting, efficient cutting for mixed turning tasks

The combination of a PVD-coated surface and a carbide substrate provides a balance between wear resistance and edge sharpness that supports consistent cycle times. As a member of the ISO DNMG150416 family, this indexable insert is intended for medium cutting depths and varying feed rates; the AH6225 grade is tuned for reliable performance when machining stainless steels. The protective coating reduces flank wear in interrupted cuts and at elevated temperatures, which often translates into fewer insert changes and lower total tooling costs per component. For production planners, this means predictable tool life and stable part quality in mixed-batch environments.

Secure mounting and straightforward compatibility with holders

Compatibility with toolholders is determined by form, clearance angle, tolerance class, fastening and the insert’s size and thickness. The insert is specified with a thickness of 4.76 mm and a nominal size of 15, with a 0° clearance angle and a 55° included angle, so matching the holder seat and clamp is crucial for repeatable accuracy. The central cylindrical hole and standard rhombic form allow quick indexing on most DNMG-compatible external holders; choosing a holder that matches the insert’s tolerance class ensures correct clamping force and minimises vibration. For workshop staff unfamiliar with insert‑to‑holder matching, check the holder data sheet for seat geometry and tolerance to ensure correct fit.

Improved edge stability and chip control for stainless steel machining

The 1.6 mm corner radius and integrated double-sided chipbreaker are selected to balance strength and finish: the radius supports edge robustness during medium turning passes, while the chipbreaker helps create controllable, segmented chips in ductile stainless steels, reducing the risk of entangling swarf. The rhombic shape provides two effective cutting edges on each side, allowing economical indexing and prompt return to dimensionally consistent cuts. In practice, this configuration helps maintain surface quality and reduces the incidence of built-up edge, so parts leave the machine within tolerance more often and post‑process rework is minimised.

FAQ

Which materials are best suited to this insert?
The DNMG150416 AH6225 Tungaloy indexable insert is optimised for machining stainless steels, offering a coating and grade combination that reduces built‑up edge and extends usable life in such materials.

How does the AH6225 grade affect machining results?
The AH6225 grade balances a sharp cutting edge with edge stability, improving surface finish and lowering the frequency of insert changes during medium turning operations.

What should be checked when fitting the insert to a holder?
Ensure the holder’s seat geometry matches the insert’s shape and 0° clearance angle, verify the clamp or screw fits the cylindrical hole, and confirm tolerance class compatibility to maintain clamping stability.

How many indexable edges are available per insert?
This rhombic, double‑sided insert provides two usable edges per side, allowing multiple repositions before replacement and helping to reduce tooling costs.

Is this insert suitable for internal as well as external turning?
Yes, the ISO DNMG geometry and AH6225 grade make the insert suitable for both external and internal turning applications, provided the holder and cutting parameters are appropriate.
