WNMG 080412 AH6225 — ISO turning insert for turning (Tungaloy)

The WNMG 080412 AH6225 is an ISO-standard trigon turning insert engineered for external and internal turning, featuring a TSF chipbreaker and a PVD-coated carbide grade optimised for stainless-steel machining.

• PVD-coated carbide grade AH6225
• Optimised TSF chipbreaker
• Trigon insert with 80° geometry
• Suitable for stainless-steel machining

Improved process reliability through a stable cutting edge

The PVD-coated carbide grade AH6225 offers a balance between edge sharpness and durability that supports consistent performance in medium turning operations. The PVD coating increases heat resistance and wear performance, reducing the frequency of tool changes and contributing to lower overall machining costs. By combining a stable, sharp cutting edge with a coating designed for adhesion under varying thermal loads, this insert helps maintain surface quality and reduces the risk of built-up edge when machining stainless steels.

Better chip control and predictable results with TSF chipbreaker

The TSF chipbreaker is designed to produce short, controllable chips under a range of cutting conditions, which improves swarf evacuation and minimises workpiece surface contamination. With an 80° cutting geometry and a 1.2 mm corner radius, the trigon shape supports sturdy engagement in external and internal turning, delivering repeatable dimensional results. For workshops less familiar with chipbreaker technology: a chipbreaker is a micro-profile on the rake that forces chips to curl and break, preventing long, hazardous swarf and reducing interruptions during production.

Practical compatibility and selection guidance for reliable setup

Compatibility with a toolholder is governed by form, clearance angle, tolerance class, fixation method, size and thickness; the insert is supplied in the ISO WNMG format and requires a matching external holder or boring bar, shim/clamp set and replacement screws for assembly. The insert is supplied with a cylindrical hole, enabling secure fastening in holders designed for ISO trigon plates. When selecting the chipbreaker and grade, match the AH6225 and TSF combination to the material’s machinability and the stability of the setup to achieve the best balance between tool life and productivity.

FAQ

Which materials is this insert best suited for?
The WNMG 080412 AH6225 is primarily designed for stainless steels; the AH6225 grade and PVD coating are selected to give a sharp, stable edge and effective wear resistance when machining austenitic and similar stainless alloys.

What advantages does the TSF chipbreaker provide?
The TSF chipbreaker on the WNMG 080412 AH6225 promotes short, controllable chips, improving swarf control and surface finish while reducing the risk of built-up edge during medium turning operations.

What are the key geometry specifications to consider?
Important specs are the 80° cutting geometry, 1.2 mm corner radius and 0° clearance angle; these influence engagement, durability and achievable surface quality for the insert.

How is compatibility with holders determined?
Compatibility depends on the insert’s form, clearance angle, tolerance class, fixation method, size and thickness; the insert is an ISO-format trigon plate and requires a matching holder or boring bar, shim/clamp set and replacement screws for secure mounting.

Is this insert suitable for internal turning and boring bars?
Yes; the ISO trigon format and cylindrical hole enable use in appropriate boring bars and holders for internal turning, provided the holder matches the insert dimensions and fastening method.
