Thread cutting
The machine is equipped with a reversible direction of rotation
and can also be used for cutting threads.
Proceed as follows for cutting threads:
Drill the hole for the thread.
Switch o the machine and select the lowest gear stage and
speed.
Set the direction of rotation to clockwise (right = R) at
switch (23).
Chuck the thread tap in the machine using the appropriate
drill tap adapter.
Switch on the machine and set the thread tap onto the drilled
hole.
Guide the machine slide down at hand lever (11) without ex-
erting pressure until the desired thread length has been cut.
Switch o the machine and set the direction of rotation to
anti-clockwise (left = L) at switch (23).
Switch on the machine again and allow the thread tap to
come completely out of the workpiece. Then guide the ma-
chine slide upwards at hand lever (11) to avoid damaging the
start of the thread.
Reaming/counter-sinking
Thanks to its wide range of operating speeds, the machine can
also be used for reaming or counter-sinking.
