DNMG150616 AH6225 Tungaloy turning insert — PVD-coated carbide, 55° rhombic

The DNMG150616 AH6225 is an ISO rhombic indexable insert designed for external and internal turning, offering a stable cutting edge for medium machining of stainless steels.

• PVD-coated carbide AH6225 for stainless steel
• 55° rhombic shape for versatile turning
• 1.6 mm corner radius for robust edge
• Double-sided insert with cylindrical hole

Consistent performance for stainless steels and mixed conditions

The insert uses a PVD-coated substrate of carbide formulated as AH6225, created to balance a sharp cutting edge with durability in variable cutting situations. The coating reduces built-up edge and increases wear resistance, which translates into more stable tool life during medium turning operations on stainless steels. The integrated chip control geometry, specified as double-sided, helps to produce predictable chips and reduces interrupted cuts, supporting smoother cycle times and less downtime for chip clearing.

Geometry that combines surface finish and edge security

A 55° rhombic profile with a 1.6 mm corner radius gives a practical compromise between edge strength and surface quality. The moderate radius contributes to improved edge robustness under fluctuating cutting forces while still allowing good surface finish on turned components. The insert’s ISO rhombic form is widely supported by standard external holders and boring bars, enabling reliable clamping and repeatable positioning in production settings — a clear advantage when consistency and repeatability are required.

ISO compatibility and economical indexing for production environments

As an ISO-standard indexable insert, the DNMG150616 fits conventional holders when matched by form, clearance angle and size; the insert features a cylindrical hole and a plate thickness of 6.35 mm, facilitating secure fixing and straightforward replacement. Being double-sided, the insert offers multiple cutting edges per insert which reduces cost per edge and simplifies inventory management. The combination of standard sizing and the universal AH6225 grade supports productive turning of various components without frequent tool changes, increasing machine uptime.

Practical application and handling guidance

For optimal results select a holder and clamping assembly that matches the insert’s 0° clearance angle and 55° lead geometry, and choose cutting parameters tuned for medium-duty turning of stainless steels. The PVD-coated carbide construction is particularly suitable when encountering variable material batches or mixed production runs, as the coating and substrate combination moderates wear while maintaining cutting performance. Where chip control is critical, the double-sided chipbreaker design helps prevent long, stringy chips and supports safer machining.

FAQ

What materials is this insert best suited for?
The DNMG150616 AH6225 insert is formulated for machining stainless steels and performs well in medium turning applications, benefitting from the AH6225 grade and PVD-coated carbide.

How many cutting edges are available per insert?
The insert is double-sided and indexable, providing multiple usable edges before replacement and improving cost efficiency per cutting edge.

Is the insert compatible with standard ISO holders?
Yes, the ISO designation and the rhombic form ensure compatibility with standard holders when matching form, clearance angle and size.

What are the key dimensions to check for holder compatibility?
Check the plate size (15 mm), thickness (6.35 mm), corner radius (1.6 mm) and the 55° geometry to ensure correct seating and clamping in the chosen holder.

Does the PVD coating affect cutting parameters?
The PVD-coated surface enhances wear resistance and reduces built-up edge, allowing stable cutting at the recommended medium machining parameters for stainless steels.
