For easy chip flow air-cooling rev. minimal quantity lubrication is recommended. Above cutting parameter are only suited for standard tools (SEF F). For tools with long flutes (SEF F-L) ap 3.0D at ae 100 n 50 und Vf 50 %. Tool overhang should be as small as possible. Number of revolutions and feed rate should be reduced to minimise vibrations.
