WNMG 080408 AH120 — Turning indexable insert, PVD-coated cemented carbide, 80° trigon (Tungaloy)

The WNMG 080408 AH120 is an ISO-standard turning insert designed for external and internal turning where a sharp cutting edge and high process reliability are required.

• PVD-coated carbide for high wear resistance
• Sharp cutting edge with process reliability
• 80° trigon with cylindrical hole for secure clamping

High wear resistance that extends tool life and uptime

The insert is a PVD-coated grade based on cemented carbide, specifically the AH120 formulation, which is engineered to resist flank wear and chipping during turning. This hardness and coating combination delivers consistent results across interrupted cuts and varying workpiece materials, reducing unscheduled tool changes. For production environments where every minute on the spindle counts, the PVD-coated surface preserves the cutting geometry and supports longer tool life without compromising surface finish.

ISO conformity and secure mounting for predictable set-up

Designed to the ISO WNMG080408 specification, the geometry ensures predictable seating and orientation in compatible holders. The 80° trigon shape with a cylindrical hole and a thickness of 4.76 mm provides reliable clamping and repeatable location, while the 0° clearance frees the insert for robust contact at the cutting edge. When replacing inserts, match form, free angle, tolerance class, fixation method, size and thickness to the holder to maintain process stability and avoid set-up issues.

Chip control and cutting-edge geometry for stable machining

The integrated chipbreaker TH was conceived for efficient chip formation in both external and internal turning. Combined with the sharp cutting edge of this grade, it supports consistent chip flow and reduces the risk of built-up edge. The result is improved surface quality and lower cutting forces in many applications. Select the chipbreaker and grade according to workpiece material and machining strategy to gain the greatest benefit from the insert’s design.

Proven productivity benefits for production turning

By using this insert in standardised holders and matching the AH120 performance profile to the workpiece, shops can expect reduced downtime, fewer insert changes and steadier cycle times. The grade’s resistance to fracture contributes to predictable tool life and fewer interruptions, which supports higher throughput and cost-efficiency in series production. For CNC turning centres and jobbing shops seeking consistent machining results, this insert brings measurable productivity advantages.

FAQ

What materials is this insert suitable for?
The WNMG080408-TH AH120 insert, with its PVD-coated cemented carbide grade, is intended for general turning tasks where wear resistance and a sharp cutting edge are required; select the chipbreaker and cutting data according to the specific workpiece material.

How does the chipbreaker TH influence machining?
The chipbreaker TH on the insert promotes controlled chip formation and evacuation in turning operations, improving surface finish and reducing the likelihood of entangled chips during continuous and interrupted cuts.

How to ensure the insert fits the toolholder?
Compatibility depends on the insert form, free angle, tolerance class, fixation, size and thickness; use holders that accept WNMG080408-TH geometry and confirm the 4.76 mm thickness and 80° trigon seating for correct clamping.

What is the main advantage of the AH120 grade?
AH120 is a PVD-coated grade designed for wear and fracture resistance in turning, offering stable cutting performance and extended tool life under typical production conditions.

Can this insert be used for internal turning?
Yes, the WNMG080408-TH AH120 is suitable for both external and internal turning when the holder geometry and reach allow for the trigon insert and the chipbreaker requirements are met.
