Applications
Thanks to its slender, acute design, this VNMG insert is perfectly suited for complex workpiece contours and tight machining spaces. It truly excels when copy turning and profiling steel components that require precise chip guidance and superior surface finishes.
Special features
The specially developed PF geometry acts as a highly effective chip problem-solver. It breaks chips early, protecting the workpiece and the tool holder from scratches or damage caused by stringy swarf. Additionally, the advanced P25 carbide grade provides the necessary toughness to perform reliably even during lightly interrupted cuts.
