The indicated speeds and feeds are for drilling with water-soluble oil or MQL. 4. Make a pilot hole before using in accordance with recommended operation. (We do not recommend mist drilling with stainless steels.) 5. A clogged oil hole can lead to breakage. Make sure that a filter is attached to 2. Water-soluble oil (20-30 times dilution) is recommended. the oil feeder. 3. When using non-water-soluble oil, set the cutting speed between 70-100% of 6.
