              Mounting Instructions
            1 Insert the chamfering ring on the drill body
              and slide to the desired position .
                                   (1)
            2 Rotate the ring clockwise until the stopper
              engages the flute edge.                                         Min. 1 mm
            3 Tighten the ring screw according to the maximum
              tightening torque indicated on page 137.
            4 Mount the chamfering insert.
            5 Mount the CHAMDRILL head.

              User Guide
              Recommendations for better stability:
            1  Use 3xD drill instead of 5xD, if possible.
            2  Mount the chamfering ring as close
              as possible to the drill shank.
            3  For better chamfering insert life, apply a
              coolant to the chamfering insert, in addition
              to the internal and/or external coolant.
            4  A wider gap “X” between the drill and the head size is                           X
              preferred (i.e. for a 14.6 mm head, use a 14 mm body                          (maximize)
              rather than 14.5 mm). A slightly larger “X” dimension
              can dramatically increase the chamfering insert life.
              (1)  The “L” dimension shown is relative to the common 1 mm chamfer.
              For other sizes, adjust “L” accordingly.
