WNMG 080416 AH120 — ISO turning insert, PVD-coated carbide, 1.6 mm radius (Tungaloy)

The WNMG 080416 AH120 is an ISO-standard turning insert for external and internal turning applications, designed for process-stable machining where a sharp cutting edge and resistance to wear and chipping are required

• PVD-coated carbide for long tool life
• Sharp cutting edge for process stability
• Trigon form with 80° lead geometry
• 1.6 mm corner radius for robust cutting

High-performance abrasion resistance for stable series production

The PVD-coated carbide grade AH120 provides a balance of abrasion resistance and edge toughness, making it suitable where both a sharp cutting edge and reliable tool life are demanded. As an ISO turning insert in the WNMG family, the component combines a thin 4.76 mm plate thickness with a hardened cutting edge treatment to reduce flank wear. This results in consistent dimensional control and reduced frequency of insert changes, supporting uninterrupted production cycles and a measurable reduction in tool-change downtime.

Engineered geometry to maintain cutting consistency and chip control

The trigon-shaped plate with an 80° lead geometry and TM chipbreaker is optimised for reliable chip formation in typical external and internal turning tasks. The 0° clearance angle and cylindrical locating hole ensure repeatable seating in compatible holders, while the 1.6 mm corner radius offers a compromise between strength at the edge and the capacity to handle moderate depths of cut. These design elements contribute directly to predictable cutting forces and improved surface finish when the grade and chipbreaker are matched to the workpiece and setup rigidity.

System compatibility and selection guidance for correct tool assembly

Compatibility with the toolholder depends on the insert’s form, clearance angle, tolerance class, fastening style, size and thickness. The ISO designation and the cylindrical hole make the insert suitable for most standard WNMG holders, provided the holder matches the 08-size and the plate thickness of 4.76 mm. Choosing the correct TM chipbreaker and the AH120 grade in the context of the material, machining type and machine stability helps to avoid premature edge chipping and achieves reproducible results across batches.

Practical machining recommendations to increase process security

For best results, pair the insert with a correctly rated cutter body, appropriate shim or clamp set and the specified screw for secure fixation. The insert’s wear behaviour under cutting conditions benefits from coolant strategies that support chip evacuation and temperature control; when higher cutting speeds or interrupted cuts are required, check holder rigidity and machining parameters before increasing feed or depth. The PVD-coated surface reduces built-up edge risk and contributes to consistent surface quality when the combination of grade and chipbreaker is aligned with the application.

FAQ

Is the WNMG 080416 AH120 compatible with standard WNMG holders?
Compatibility is determined by holder form, clearance angle, tolerance class, fastening, size and thickness; the WNMG 080416 AH120 fits standard holders designed for 08-size WNMG inserts with a 4.76 mm plate thickness.

Which machining tasks suit this insert best?
The AH120 grade with TM chipbreaker is intended for general turning tasks requiring a sharp cutting edge and process stability, including both external and internal turning operations.

How does the PVD coating on AH120 influence performance?
The PVD coating improves wear resistance and reduces adhesion on the cutting edge, extending tool life and helping to maintain surface finish consistency under normal cutting conditions.

What should be considered when clamping this insert?
Use the correct clamp, underlay and screw specified for WNMG inserts; the cylindrical locating hole and standard fastening ensure reliable seating when the corresponding holder geometry and tolerance class are observed.

Can the insert handle interrupted cuts or heavy feeds?
The 1.6 mm corner radius and the AH120 grade offer increased edge strength for moderate interrupted cuts or higher feeds, but machine and holder rigidity should be verified to maintain process security.
