- The cutting parameters shown in the table are a starting guideline.
Values should be varied depending on the power or rigidity of the machine.
Optimum conditions should be selected depending on the actual chip control or damage on edges. - When using the smaller diameter tools in each range, set the feed “f” to the lower values.
- When drilling with a depth deeper than L/D = 3, a pecking cycle or dwell operation should be considered depending on the actual chip control.
