Applications
Thanks to its specialized geometry, the RTHX indexable insert is highly suited for fine finishing operations under stable machine conditions. The tool supports efficient workflows on modern CNC milling machines and can be flexibly used for machining steel, stainless steel, and cast iron. It is a practical choice whenever strict requirements for dimensional accuracy and final surface quality must be met.
Special features
The combination of a positive rake angle and a double clearance angle results in a very smooth cutting action, effectively reducing mechanical loads during the machining process. This sharp yet sturdy design minimizes potential vibrations, encourages efficient chip evacuation, and supports continuous and reliable finishing cycles.
