DNMG 150604 AH6225 Turning insert by Tungaloy — PVD-coated carbide, 55° rhombic

The DNMG150604 AH6225 indexable turning insert is designed for external and internal turning of stainless steels, offering a sharp yet robust cutting edge for varied medium-duty operations.

• PVD-coated carbide grade AH6225
• Optimised for stainless steel machining
• Double-sided chipbreaker for consistent chips
• Rhombic DNMG shape, 15 mm size

Reliable cutting performance for stainless steels

The insert’s PVD-coated carbide substrate (grade AH6225) combines surface hardness and thermal stability to reduce flank wear and resist built-up edge under changing cutting conditions. The coating reduces adhesion and improves heat resistance, which means the cutting edge remains sharper for longer and process stability is increased. For production environments where repeatability and consistent surface finish are essential, this geometry supports steady metal removal rates and fewer tool changes, contributing to predictable cycle times and lower unit costs.

Geometry and dimensions that simplify setup and inventory

The rhombic DNMG form with a nominal 55° cutting geometry and a 0.4 mm corner radius provides a balanced compromise between strength and edge acuity. The insert measures 15 mm across with a plate thickness of 6.35 mm and a 0° clearance angle, and it features a cylindrical hole for secure mounting. The double-sided chipbreaker enables indexing to refresh the cutting edge, improving utilisable tool life and reducing spare-part variety. Compatibility with holders is governed by form, clearance angle, tolerance class, fastening method, size and thickness, so selection of a matched ISO holder ensures correct seat and repeatable clamping.

System integration and machining economy

In practice the insert is used as part of an ISO tooling system comprising a suitable external holder or boring bar, a clamp or shim set and replacement screws. The insert’s universal grade and chip control allow a single grade to cover a wide range of stainless steels and mixed batches, reducing tooling complexity. When combined with stable machine setup and appropriate feeds and speeds, the result is improved process security and good surface quality. The insert’s design supports quick indexation, straightforward inventory management and consistent results across short and mid-length production runs.

FAQ

Is this insert suitable for stainless steels?
The DNMG150604 AH6225 insert from Tungaloy is formulated specifically for stainless steel applications; the AH6225 grade and PVD coating provide edge stability and good wear resistance during turning of rostfreier Stahl.

How is the insert mounted in the holder?
The insert uses a cylindrical hole and must be clamped in a compatible ISO external holder or boring bar; correct compatibility depends on form, clearance angle, tolerance class, fastening method, size and thickness.

What does double-sided chipbreaker mean for tool life?
A double-sided chipbreaker allows the insert to be indexed to present fresh cutting edges on both faces, extending effective cutting life and reducing the frequency of replacements for the same Tungaloy insert.

Which operations are typical for this geometry?
The rhombic DNMG geometry with a 55° approach is suited to both external and internal turning tasks where a balance of edge sharpness and robustness is required; it is suitable for medium-duty machining and mixed-production environments.

Are there special requirements for selecting feeds and speeds?
Feeds and speeds should be chosen according to the machined stainless steel grade, toolholder rigidity and machine capability; the AH6225 grade is tolerant to varying conditions but benefits from consistent clamping and appropriate coolant or lubrication strategies.
