WNMG 080408 AH6235 (WNMG080408-SS) — ISO turning insert, PVD-coated carbide, Tungaloy

The WNMG080408-SS AH6235 is an ISO-standard turning insert designed for external and internal turning, optimised for stainless steel and applications with interrupted cuts.

• PVD-coated carbide grade AH6235
• Optimised for stainless steel machining
• Trigon insert with 0.8 mm corner radius
• Cylindrical hole, 4.76 mm plate thickness

Performance and productivity for demanding stainless steel turning

The combination of a PVD-coated surface and the AH6235 substrate delivers increased edge toughness and thermal resistance, which translates into longer tool life in demanding conditions. As a result, cycle times remain stable when machining stainless steel or when facing frequent interruptions in the cut. The coating reduces built-up edge and improves wear behaviour, while the tougher substrate mitigates chipping during unstable cutting. This balance of hardness and toughness supports higher uninterrupted runtimes and contributes to consistent component quality in series production.

Secure clamping and ISO compatibility minimise setup issues

The insert follows ISO dimensions and form features that determine holder compatibility: shape, clearance angle, tolerance class, fixing method, size and thickness. The trigon form with a cylindrical centre hole ensures positive location in compatible holders, while the 4.76 mm plate thickness increases rigidity during heavier cuts. These design elements reduce the risk of improper seating and the resulting vibration, lowering the chance of premature edge failure. For workshop planners, this means fewer interruptions from re-seating or rejected parts and a smoother production flow.

Predictable surface finish and controlled chip formation

The integrated SS chipbreaker and a 0.8 mm corner radius provide a balance between edge strength and surface quality. The moderate corner radius supports robust cutting edge life and contributes to repeatable dimensional results, while the chipbreaker geometry manages swarf when turning stainless steel or mixed materials. Choosing the correct chipbreaker and grade for workpiece stability is essential: this insert’s combination is particularly suitable where breakage risk is elevated and where consistent part finish is required over longer production runs.

System integration and application guidance for reliable use

This insert is part of an ISO-indexable system comprising the plate, matching external holder or boring bar, backing/clamping set and replacement screws. The 0° clearance angle and the 80° wedge angle influence how the insert interacts with the holder and workpiece; they should be considered when selecting tooling geometry for a task. For best results, pair the insert with a holder that matches the plate form and tolerance class, select feeds and speeds appropriate to stainless steel and interrupted cuts, and use coolant strategies that support chip evacuation and thermal control. Metav Werkzeuge can advise on optimal holder selection and process parameters to integrate the indexable insert into existing setups.

FAQ

What is the ISO designation of the insert?
The ISO designation is WNMG080408-SS; the insert is supplied as WNMG080408-SS AH6235 by Tungaloy and follows ISO form and size conventions.

Which materials is this grade intended for?
The AH6235 grade is formulated for machining stainless steel and is well suited to interrupted cutting where increased edge toughness is required.

What are the key dimensional features to check for holder compatibility?
Check plate form (trigon), size (08), plate thickness (4.76 mm), clearance angle (0°) and the cylindrical centre hole style to ensure compatibility with the chosen holder.

How does the 0.8 mm corner radius affect performance?
A 0.8 mm radius increases edge strength and wear resistance, improving durability under variable cutting loads while maintaining acceptable surface finish for many turning tasks.
