WNMG 080408 AH120 ISO trigon indexable insert for turning (Tungaloy)

WNMG080408-SA AH120 is an ISO-standard trigon insert designed for external and internal turning, providing a sharp cutting edge and consistent process security in industrial machining.

• PVD-coated carbide AH120 durable wear resistance
• Trigon insert, 80° geometry, 0.8 mm radius
• SA chipbreaker for controlled chips
• Cylindrical-hole for secure clamping

Reliable cutting performance for continuous production

The combination of a PVD-coated surface and the AH120 grade delivers improved resistance against abrasion and microchipping while maintaining a sharp cutting edge. For machining operations that require tight tolerances and steady metal removal rates, the cemented carbide substrate ensures dimensional stability at elevated cutting temperatures. This balance of toughness and hardness supports reproducible cycle times and reduces unscheduled tool changes, contributing to uninterrupted production flow.

Simple integration with ISO tool systems

As an ISO-design insert, compatibility depends on insert form, clearance geometry, tolerance class, attachment method, size and thickness. The trigon form and 0° clearance make this insert suitable for a wide range of standard external holders and boring bars when the seating matches the trigon pocket. The cylindrical hole aids secure clamping and repeatable positioning; selecting the correct top clamp and screw ensures stable cutting conditions and minimises vibration-related wear.

Stable chip control and process security

The SA chipbreaker is geared toward reliable chip formation under varying cutting conditions, facilitating smooth evacuation and reducing the risk of re-cutting. When paired with the AH120 grade, the insert is particularly effective where a sharp edge and high process security are required. Consistent chip control shortens cycle interruptions and supports better surface finish, making the insert suitable for both semi-finishing and finishing passes when appropriate cutting parameters are chosen.

Practical handling and selection guidance

Indexable inserts must be matched to the machining task and clamping system. The WNMG geometry offers multiple cutting edges by indexing; checking the insert seating, screw specification and holder compatibility avoids downtime. The insert’s label and manufacturer article numbers facilitate correct reordering and traceability for tool management systems, while routine inspection of the cutting edge helps to plan replacements proactively and keep workpiece quality constant.
