The indicated speeds and feeds are for drilling with water-soluble oil or MQL. 4. These conditions are for drilling depth under 8 times the drill diameter. 2. Suitable cutting fluid is water-soluble high density oil (less than 20 times dilution). 5. 1D-2D step feeding may be required for drilling high hardened steels andmid-range (8D) work. 3. When using non-water-soluble oil or water-soluble oil (over 20 times dilution), reduce cutting speed by 30%. 294 Drilling Technical WWW.OSGTOOL.COM
