High-Performance TNMG-PF Turning Inserts for Professional Machining

The TNMG-PF RT325G indexable insert was specifically developed to achieve excellent chip formation when machining steel materials. It reliably covers the range from finishing to medium machining and excels particularly with soft and tough material characteristics. Equipped with a CVD-coated P25 carbide grade, it offers high wear resistance, making operations highly reliable in both continuous and slightly interrupted cuts. The economical design (supplied in packs of 10) makes this turning insert an efficient solution for regular turning tasks in industrial applications.

Applications

The TNMG-PF RT325G is the ideal choice for turning processes on steel workpieces that require clean surfaces and dependable chip breaking. Because the geometry is precisely tailored to handle soft and tough materials, it is highly suitable for finishing and medium applications in both single-part and series production. Even with light cutting interruptions, the robust coating delivers consistent results without premature tool wear.

Special features

The combination of the specific PF geometry and the RT325G carbide makes this cutting insert a true problem-solver for chip control. Optimized chip formation not only protects the workpiece from scratches caused by chip jamming but also significantly contributes to achieving the required surface finishes. This effectively supports efficient and smooth workflows in metalcutting manufacturing.
