Note: 1. The indicated speeds and feeds are for drilling with water-soluble oil or MQL . (We do not recommend mist drilling with stainless steels.) 2. Water-soluble oil (20-30 times dilution) is recommended. 3. When using non-water-soluble oil, set the cutting speed between 70-100% of the lowest limit. 4. Make a pilot hole before deep drilling; recommended operation is on pages 310-311.
5. A clogged oil hole can lead to breakage. Make sure that a filter is attached to the oil feeder. 6. Peck drilling of 1D-2D is strongly recommended in high hardness materials. 7. If, after piloting with ADO-5D and drilling with ADO-40D/50D, hole condition or accuracy is poor or machining is difficult, ADO-20D/30D may be used as an intermediate drilling step. This three-step process may improve accuracy and condition as well as permit more aggressive parameters than stated above.
