WNMG 080412 AH120 — Indexable turning insert (trigon), PVD-coated carbide, 1.2 mm radius — Tungaloy

The WNMG080412-TSF AH120 is an ISO‑standard trigon indexable insert for external and internal turning, engineered for process stability where a sharp cutting edge and consistent performance are required.

• ISO-standard trigon format
• PVD-coated carbide grade AH120
• TSF chipbreaker for stable chips
• 1.2 mm corner radius for robust cutting

Optimised cutting edge for stable production

The PVD‑coated carbide grade AH120 combines a wear‑resistant substrate with a thin, hard coating to keep the cutting edge sharp under repetitive loads. This results in more consistent dimensional accuracy and surface finish during extended runs. The TSF chipbreaker actively shapes chips to reduce entanglement and clearances in confined setups, which lowers the risk of workpiece damage and interrupts machining far less frequently. These technical choices translate into fewer tool changes and improved overall equipment effectiveness.

ISO compatibility and application flexibility

As an ISO-standard insert in trigon form, compatibility with holders depends on form, clearance angle, tolerance class, fixing, size and thickness. The 0° clearance angle and 1.2 mm corner radius are suited to operations requiring a strong tip for heavier cuts while maintaining acceptable surface quality; the trigon shape provides three usable cutting edges per index, improving economy. Select the chipbreaker and grade to match the workpiece material, machining strategy and machine–fixture rigidity to achieve the intended process security and repeatability.

Practical system integration and economic benefits

The insert is designed to work within a standard system: an ISO indexable plate plus a matching external holder or boring bar, backing/shim and clamping screws. This enables fast index changes and simple inventory management. Using a PVD-coated grade with a reliable chipbreaker reduces unplanned stoppages, contributing to lower machining costs per component and predictable scheduling. For workshops aiming to balance productivity with tool life, the model series delivers repeatable results and straightforward handling in everyday turning tasks.

FAQ

What machining tasks is this insert intended for?
The WNMG080412-TSF AH120 is intended for external and internal turning where a sharp edge, process security and reliable chip control are required.

Which materials can be machined with this grade and chipbreaker?
The AH120 PVD‑coated carbide with the TSF chipbreaker is chosen for general turning applications; the final selection should match the workpiece material, cutting data and machine rigidity.

How is the insert mounted and indexed?
This ISO‑standard trigon insert is used with a matching external holder or boring bar, plus backing/shim and clamping screws; the trigon form provides multiple usable edges per insert.

What do the dimensions 08 and 080412 indicate?
Size "08" denotes the insert size class; "080412" refers to the ISO designation that includes size and corner radius details for consistent holder compatibility.

Can the insert reduce downtime compared with conventional grades?
Yes, the PVD-coated AH120 and TSF chipbreaker are specified to improve wear resistance and chip control, which helps reduce unplanned tool changes and machine stoppages.
