SNMG 120408 AH6235 indexable insert for turning by Tungaloy — PVD‑coated carbide, 0° clearance

The SNMG120408 AH6235 Tungaloy insert is an ISO‑standard, square indexable insert designed for external and internal turning, optimised for stainless steels and interrupted‑cut applications.

• PVD-coated carbide grade AH6235
• Optimised for stainless steels and interrupted cuts
• Double-sided chipbreaker for stable chips
• ISO SNMG120408 with cylindrical hole

High edge security for demanding turning operations

The combination of a PVD‑coated surface and a tougher carbide substrate in grade AH6235 increases resistance to chipping and flank wear under unstable cutting conditions. For components made from stainless steel or where interrupted cuts are frequent, this translates into longer edge life and fewer indexings per workpiece batch. The result is a measurable improvement in process stability and consistent surface finish, reducing scrap rates and helping maintain tight tolerances in production.

Predictable chip control that reduces secondary operations

The double-sided chipbreaker geometry is engineered to produce short, controllable chips across a range of feeds and depths of cut. With a corner radius of 0.8 mm and the defined geometry of the insert, the cutting forces are distributed in a way that improves vibration behaviour and surface integrity. This leads to fewer downstream operations such as rework or manual deburring and contributes to overall cycle‑time savings on both turning centres and turret lathes.

ISO compatibility and straightforward toolroom handling

As an ISO‑standard SNMG120408 insert with a cylindrical hole, the part is compatible with a broad range of ISO external holders and boring bars; compatibility depends on form, relief angle, tolerance class, fastening method, size and thickness. The 4.76 mm plate thickness and square form offer simple indexing and a clear replacement routine, which limits machine downtime and simplifies inventory management. Where tool systems are shared across several machines, the standardised interface helps ensure predictable mounting and repeatable cutting performance.

Practical benefits for series production and mixed batches

Designed for turning applications where material mix and interrupted cuts occur, this insert offers a cost‑effective way to balance tool life and part quality. The robust grade minimises unplanned tool changes under difficult cut conditions, while the coated surface supports elevated cutting speeds when process stability allows. For production planners, this means a lower total cost of machining and more reliable lead times.

FAQ

What materials is this insert best suited for? This SNMG120408 AH6235 insert is optimised for machining stainless steel and performs well in interrupted cutting conditions.

Is the insert reversible or single-use? The SNMG120408 AH6235 is double-sided, allowing reversible indexing to extend the usable life of the insert.

How does the AH6235 grade affect cutting parameters? The AH6235 grade provides increased toughness and chipping resistance; as a result, reliable performance can be achieved at moderate to elevated cutting speeds with reduced risk of edge failure.

Which holder types are compatible with SNMG120408? Compatibility depends on the holder’s form, clearance angle, tolerance class and fastening method; SNMG120408 follows ISO dimensions and fits standard ISO external holders with a cylindrical hole interface.

What operational benefits does the PVD coating provide? The PVD coating enhances wear resistance and reduces built‑up edge formation, improving tool life and surface finish during production turning.
