WNMG080412-SA AH120 — ISO indexable turning insert for turning, PVD-coated AH120 (Tungaloy)

WNMG080412-SA AH120 is an ISO-standard indexable insert designed for reliable external and internal turning in industrial machining environments, compatible with standard holders that accept the WNMG form and dimensions.

• WNMG geometry for ISO turning holders
• PVD-coated carbide AH120 for wear resistance
• SA chipbreaker for stable chip control
• 80° trigonal insert with 1.2 mm corner radius

Durable cutting edge for long production runs

The combination of a PVD-coated surface and a carbide substrate provides enhanced wear resistance, extending the interval between index changes and reducing downtime. The AH120 grade is engineered to resist both flank wear and chipping under intermittent loads, which supports predictable tool life and repeatable batch quality. For operations where a sharp cutting edge and consistent performance are central, this configuration reduces scrap rates and contributes to a steady production flow.

Predictable chip control for safer machining

The SA chipbreaker geometry was selected to promote controlled chip formation during turning, which helps maintain machine uptime and operator safety. A defined chip shape reduces the risk of entanglement and eases chip evacuation from the cutting zone, improving surface finish and preventing workpiece damage. By favouring stable chips, the insert supports higher process reliability and simplifies post-process handling in busy shop-floor conditions.

Practical compatibility and integration benefits

As an ISO-standard insert with a trigonal plate form and an 80° included angle, the component fits a wide range of external holders and boring bars when matched by form, clearance angle, tolerance class, fastening and thickness. The 1.2 mm corner radius balances edge strength with achievable surface quality, and the presence of a cylindrical hole ensures secure fastening. This system-oriented approach makes the insert easy to incorporate into existing tooling setups, enabling quick changeover and predictable performance in both roughing and finishing turning operations.
