The indicated speeds and feeds are for drilling with water-soluble oil. 4. These conditions are for drilling depth under 3 times the drill diameter. 2. Suitable cutting fluid is water-soluble high density oil (less than 20 times dilution). 5. For machines that cannot achieve the speeds indicated in the table please set 3. When using non-water-soluble oil or water-soluble oil (over 20 times dilution), rotation as high as possible. Tool life may be reduced. reduce cutting speed by 30%. 298 Drilling Technical WWW.OSGTOOL.COM
