DNMG150408 AH6235 Tungaloy – ISO turning insert, PVD-coated carbide for stainless steel

DNMG150408 AH6235 Tungaloy is an ISO‑standard rhombic insert for external and internal turning, optimised for interrupted cuts and applications with increased breakout risk

• PVD-coated carbide grade AH6235
• Optimised for stainless steel machining
• Double-sided chipbreaker for stability
• ISO DNMG150408, rhombic 55° form

High‑performance grade for demanding stainless‑steel turning

The DNMG150408 AH6235 Tungaloy insert combines a tougher carbide substrate with a PVD-coated surface to resist notch wear and reduce built‑up edge when machining stainless steel. The AH6235 grade is formulated for applications where material adhesion and intermittent engagement increase edge stress; the result is a noticeably more stable cutting edge and extended in‑service intervals. This engineered combination delivers predictable tool life and consistent surface quality in batch production and repair work alike.

Secure seating and repeatable geometry for fast set‑up

Designed to the ISO DNMG form, the rhombic 55° geometry with a cylindrical hole and standard fastening dimensions ensures compatibility with a wide range of external holders and boring bars. The insert’s 55° approach angle provides a compromise between cutting force and accessible clearance, while the standard tolerance class and thickness support repeatable positioning. Specifying an insert that matches the holder form, clearance angle and thickness reduces set‑up time and minimises indexing errors, improving overall process reliability.

Stability and chip control for productive turning

A double‑sided chipbreaker on this insert gives two usable cutting edges and stable chip formation under varied conditions, supporting higher material removal rates with fewer interruptions. The 0.8 mm corner radius balances edge strength and surface finish, lowering the risk of chipping on interrupted cuts. The 4.76 mm plate thickness contributes to rigidity, helping to absorb machining loads and reduce vibration. Together, these features enhance productivity and lower per‑component tooling cost through extended edge use.

Coating and material technology explained for practical selection

The PVD coating applied to the AH6235 grade enhances wear resistance and thermal stability, especially important when machining adhesion‑prone alloys. PVD films provide a hard, thin barrier that reduces flank wear and improves edge retention without compromising toughness. For best results, select the chipbreaker style and grade to match the workpiece, cut type and machine stability—this insert is particularly suited for stainless steel and interrupted operations where edge robustness is decisive.

FAQ

What materials is this insert best suited for?
The DNMG150408 AH6235 insert is optimised for stainless steel and similar adhesion‑prone alloys; the AH6235 grade is formulated to resist notch wear and edge breakdown in interrupted cutting.

Is this insert compatible with standard DNMG holders?
Compatibility depends on holder form, clearance angle, tolerance class, fastening and thickness; the DNMG150408 conforms to ISO dimensions and fits standard DNMG external holders when specifications match.

How many cutting edges are available per insert?
This version features a double‑sided chipbreaker, providing two usable cutting edges before indexing.

What does the PVD coating provide in practical terms?
The PVD coating improves wear resistance and thermal stability, reducing flank wear and built‑up edge for longer, more consistent cutting performance in tough materials.

Can this insert be used for internal turning and boring?
Yes; the rhombic 55° form and ISO sizing allow use in both external and internal turning, provided the holder geometry and assembly suit the required reach and rigidity.
