Applications
This insert set is designed for the economical contour machining and the production of internal threads in mechanical engineering and toolmaking. Thanks to the universal grade RT315 (P15-P25 and M10-M25), steel, stainless steel, non-ferrous metals, and special materials can be processed reliably. The different pitches included in the set create favorable conditions for high flexibility during varying thread turning requirements in daily manufacturing practice.
Special features
A decisive feature of these indexable inserts is the specially designed chip former, which actively contributes to controlled chip breaking and thus minimizes disruptions during internal machining operations. The full profile ensures that the thread crest and flank angle are precisely generated in the same pass, supporting high profile accuracy. Furthermore, the multi-layer PVD coating of the RT315 grade contributes to an advantageous tool life even during more demanding cutting tasks.
