1.1 Intended use
Usage
The thread cutting device is mainly used for pillar drilling machines and bench drills.
The direction of rotation is changed via the integrated reversing gear by retracting the machine
spindle.
Advantages:
Time saving due to shorter cycle times.
Handling the machine with care.
Energy saving due to almost constant power consumption.
The prerequisite for using the thread cutting device is that it is mounted in a driven machine
spindle. After insertion into the machine, the retaining bar must be secured against twisting in
both directions of rotation. The thread cutting device is equipped with a length compensation in
tension and compression direction. This compensates for differences between spindle feed and
tap pitch. An overload clutch is integrated into the thread cutting device. The taps are picked up
and centred via flexible collets.
The torque generated during the thread cutting process is transmitted via adjustable and
floating driving cams.
The thread cutting device is not designed for internal coolant supply.
The thread cutting device is suitable for cutting right-hand and left-hand threads.
We will not be held liable for any damages resulting from any operation which is not in
accordance with the intended use.
1.2 Safety instructions
WARNING!
Before using the thread cutting device, make sure
that there is no danger to persons
and no damage to property.
Avoid any unsafe work methods:
Make sure that your operation does not create a safety hazard.
The rules specified in these operating instructions must be observed during assembly,
operation, maintenance and repair.
Do not work on the thread cutting device, if your concentration is reduced, for example,
because you are taking medication.
Observe the accident prevention regulations issued by your Employers Liability Insurance
Association or other supervisory authorities applicable to your company.
Inform the supervisor about all hazards or faults.
Use the prescribed personnel protective equipment. Wear tight-fitting clothes and a hair net
if necessary.
The instructions of the machine tool manufacturer still apply.

CAUTION!
The machine tool must be secured against
restarting when the thread cutting device is
mounted. Follow the instructions of the
machine tool manufacturer.
Img.1-4: Securing assembly
Mount the thread cutting device in the receptacle of the machine spindle.
Secure the support bar against twisting in both directions.
Ensure free guidance of the support bar for the entire spindle travel.
1.7 Operation
INFORMATION
This device is intended for use on drilling machines without a tapping device with
automatic reversal of the direction of rotation. The speed of the machine used for thread
cutting should therefore be kept as low as possible, but not exceed 200 rpm.
Manual retraction of the drilling sleeve in time to reverse the direction of rotation of the
tapping attachment is hardly possible if the speed of the drilling machine is too high.
The slipping clutch is active for too long and thus heats up too quickly and too much.
1.8 Insert tap
The tap is clamped by
adjustable and floating drive
cams. The tap is centred via
the collet chuck.
Unscrew the clamping nut
from the thread cutting
device.
Place the required collet in
the clamping nut.
Screw the clamping nut with collet onto the thread of
the clamping head
Push the tap into the collet.
Tighten the clamping nut firmly using an open-ended
spanner.
Img.1-5: Tap installation
The integrated overload clutch interrupts the torque transmission between machine spindle and
tap during the tapping process if the set torque is exceeded. This protects the tap from damage.
WARNING!
Torque adjustment may only be carried out when the machine is switched off.
The torque setting depends on various factors, e.g. speed, material, lubrication. Therefore, no
torque values can be given.

1.9 Torque adjustment
Loosen the grub screw in the
torque adjustment ring.
Set the torque adjustment ring
to the lowest torque value (turn
clockwise as far as it will go).
Make a test thread before you
start cutting a larger number of
threads.
Img.1-6: Overload clutch
If the clutch slips. Increase the torque via the adjusting ring and fix the setting by tightening
the grub screw.
Cut the thread again.
Reduce torque turn clockwise.
Increase torque turn counterclockwise.
After reaching the thread depth, retract the tool spindle. The spindle of the tapping
attachment reverses the running direction.
After leaving the cut thread, the tapping attachment automatically switches back to the previous
direction of rotation.
ATTENTION!
When retracting the tool spindle, make sure that the length compensation is not pulled
out completely on tension. Avoid jerky retraction of the spindle.
The direction of rotation is changed in counterclockwise rotation (left-hand thread) and
clockwise rotation (right-hand thread).

1.10 Maintenance and servicing
Clean the tapping attachment with a hand cloth.
Do not use aggressive solvents.
Do not use fibrous materials.
The thread apparatus is not lubricated.
Spray or rub the tapping attachment with a preservative oil to prevent rusting and to
preserve the running of the tapping attachment.
Remove all coolant residues and machining residues before storage.
