This table is a guideline for selecting cutting parameters. Adjust them as needed according to the machine and workpiece conditions. Be sure to use safety enclosures, as chips may scatter. Do not use oil-based cutting fluid, as there is a risk of fire. Dry cutting is recommended for stainless steel as well; however, wet cutting may extend insert life in case severe built-up edge occurs. ! CAUTION
