DNMG 150404 AH6225 indexable turning insert (rhombic, 0° rake) — Tungaloy

The DNMG150404 AH6225 is an ISO rhombic indexable insert for external and internal turning, engineered for medium machining of rostfreier Stahl with a focus on consistent edge life and reliable chip control.

• PVD-coated carbide grade AH6225
• ISO DNMG 150404 rhombic profile
• Double-sided chipbreaker, cylindrical hole

Proven edge performance for medium turning operations

The combination of a PVD-coated surface and a carbide substrate delivers a durable cutting edge that balances sharpness and stability. The applied coating AH6225 reduces flank wear and supports stable chip formation when machining rostfreier Stahl, which helps to maintain part accuracy over longer production runs. This leads to fewer interruptions for insert changes and a more predictable tool life, making the solution attractive for series production and mixed-batch work.

Geometry and clamping: predictable compatibility and secure fixation

Built to the ISO DNMG 150404 shape with a rhombic form and a 0° rake, the insert gives a mix of cutting versatility and edge robustness. The geometry requires a matching holder by form, clearance angle, tolerance class, fastening method, size and thickness; correct pairing reduces vibration and secures repeatable results. The cylindrical hole and standard fastening allow use in many commercial DNMG-capable toolholders, simplifying stocking and holder management across turning centres and lathes.

Practical chip control and material adaptability for reliable machining

The double-sided chipbreaker supports effective chip segmentation in medium cuts, improving evacuation and surface finish while extending usable edge life through indexed turning. Because the grade is specified for rostfreier Stahl, the cutting edge sustains performance across changing conditions, such as variable feed or interrupted cuts. For customers less familiar with coatings: PVD (physical vapour deposition) places a thin, wear-resistant layer on the carbide substrate to improve adhesion and thermal resistance without sacrificing edge sharpness.

FAQ

Which materials is this insert designed for?
The DNMG150404 AH6225 insert is specified primarily for rostfreier Stahl and performs well in medium turning tasks where a balance of sharpness and edge stability is required.

How does the AH6225 coating improve performance when machining rostfreier Stahl?
The AH6225 PVD coating increases wear resistance and thermal stability, promoting consistent chip formation and reducing flank wear during extended machining of rostfreier Stahl.

What must be checked to ensure holder compatibility?
Compatibility depends on the holder's form, clearance angle, tolerance class, fastening type, size and plate thickness; matching these parameters ensures secure clamping and repeatable machining.

Is the insert reversible or indexable on both sides?
Yes, the double-sided design provides two usable cutting edges per index, extending the effective life before replacement.

What are the manufacturer's article number and SKU for ordering?
The article number is 6825893 and the manufacturer SKU is TUN6825893 for the DNMG150404 AH6225 indexable insert.
