With several nose radii and thickness options, it is suitable for both general production and more detail-oriented turning jobs.
- Application: Semi-finishing turning for steel components with better accessibility than 80° inserts
- Chipbreaker: GM chipbreaker
- Recommended grade note: Typically paired with CVD grades such as HR8105 / HR8115 / HR8225
