Indexable insert SNMG...-PM RT225+ for powerful turning processes
The SNMG...-PM RT225+ indexable insert by Rinaldi-Tools is a high-performance cutting solution for professional steel machining. The combination of the robust, square insert shape and the targeted PM chipbreaker creates excellent conditions for efficient chip control during medium machining tasks. The two-color, latest-generation P20 carbide benefits from a resilient CVD coating. This supports reliable performance and makes it a well-conceived choice for continuous turning processes and light interrupted cuts in steel materials.

Applications
Thanks to its negative basic shape and the PM chipbreaker, the SNMG turning insert is predestined for longitudinal and facing operations on steel components. It demonstrates its strengths particularly in medium turning applications. The cutting geometry enables controlled chip evacuation, which increases process reliability, especially in automated turning operations.
The CVD-coated RT225+ carbide grade proves its worth both in smooth, undisturbed cuts and in situations with slight interruptions. The wide range of available corner radii and insert sizes opens up flexible application possibilities for users, allowing them to professionally handle a wide variety of workpiece contours and allowances in daily machine use.
Special features
The square geometry of the turning insert offers the decisive economic advantage of eight usable cutting edges, which effectively optimizes tool costs per component. In combination with the modern two-color coating, the wear status of the cutting edges can be assessed quickly and easily visually, facilitating tool changes and helping to reduce machine downtimes.
