1. The indicated speeds and feeds are for drilling with water soluble oil. 2. When using non-water soluble oil, reduce the drilling speed by 20%. 3. When entering on a curved or inclined surface, reduce the feed rate accordingly. 4. When using a coated tool, the drilling speed can be increased by 1.2 times the value in the table.
