              Drilling Process on Machining Centers              1 Drill a 15 mm pilot hole flat bottom
              and Lathe Machines
                                  +0.05
            1  Drill a 15 mm pilot hole D +0.03 flat bottom

            2  Set the TRIDEEP drill into the pilot hole
              (10 mm depth). Vc=5-10 m/min f=0.5-1.0 mm/rev
            3  Initial cutting at a 25 mm DOC (80% feed rate),
              verify activated coolant (Vc=100%).                                                     15
            4  In case of through hole, drill the full
              hole to a depth of +5 mm.
            5  Retract with slow rotation (5-10 m/min).
                                                                 2 Slow rotation and feed while entering to the pre-hole
