* For ap, in case of cutting pre-drilled workpieces (same as when using a Boring Bar).
Drill type 2D~3D type 4D~5D type e.g.) In case of cutting using DRZ3090-10 (3D type)
ap 0.1D or less Not recommended For milling, pre-drilled hole should be cut bigger than 24 (30-0.1x30x2)
For turning, ap should be set under ap = 3mm (0.1x30)
For ap in case of using outer coolant system
• In case of using outer coolant system, chip evacuation will be bad.
Therefore ap should be measured within 1.5times (1.5xD) of cutting diameter (D).
