information’’ , including the figures, specifications, safety regulations and the signs indicating
DANGER, WARNING and CAUTION.
WARNING: When using electrical tools basic safety precautions should always be followed to
reduce the risk of fire, electrical shock and personal injury.
Please also observe the relevant national industrial safety regulations. Non-observance of the safety
instructions can lead to an electric shock, burns and/or severe injuries.
This manual should be kept for later use and enclosed with the magnetic drilling machine, should it
be passed on or sold.
Work area
1. Keep your work area clean and well lit. Cluttered and dark work areas increase the change of
accidents;
2. Do not operate a magnetic drilling machine in explosive atmospheres, such as in the
presence of flammable liquids, gases or dust. A magnetic drilling machine may create sparks
which could ignite the dust or fumes;
3. Keep bystanders, children and visitors away while operating a magnetic drilling machine.
Distractions can cause you to lose control.
Electrical safety
1. A magnetic drilling machine plug must match the outlet. Never modify the plug in any way.
Do not us any adapter plugs;
2. Avoid body contact with grounded surfaces such as pipes, radiators, ranges and refrigerators.
There is an increased risk of electric shock if your body is grounded;
3. Do not expose the magnetic drilling machine to rain or wet conditions. Water entering a
machine will increase the risk of electric shock;
4. Do not abuse the cord. Never use the cord to carry the magnetic drilling machine or pull the
plug from an outlet. Keep the cord away from heat, oil, sharp edges or moving parts. Replace
damaged cords immediately. Damaged cords increase the risk of electric shock;
5. When operating a magnetic drilling machine, use an extension cord suitable for outdoor use,
this reduces the risk of electric shock;
6. If operating a magnetic drilling machine in a damp location is unavoidable, use a residual
current device (RCD), this reduces the risk of electric shock.

5
Personal safety
1. Stay alert, watch what you are doing and use common sense when using a magnetic drilling
machine. Do not use the machine while tired or under the influence of drugs, alcohol, or
medication. A moment of inattention while operating a magnetic drilling machine may result
in serious personal injury;
2. Dress properly. Do not wear loose clothing or jewelry. Keep your hair, clothing and gloves
away from moving parts. Loose clothes, jewelry or long hair can be caught in moving parts;
3. Avoid accidental starting. Be sure the switch is off before plugging the machine in. Carrying a
magnetic drilling machine with your finger on the switch or plugging in a magnetic drilling
machine that has the switch on increases the change of accidents;
4. Never place hands, fingers, gloves or clothing near drilling area or rotating machine parts;
5. Remove adjusting keys or switches before turning the machine on. A wrench or a key that is
left attached to a rotating part of the machine may result in personal injury;
6. Do not overreach. Keep proper footing and balance at all times. Proper footing and balance
enables better control of the magnetic drilling machine in unexpected situations;
7. Use safety equipment. Always wear eye protection. Dust mask, non-skid safety shoes, hard
hat and hearing protection must be used for optimal safety;

drilling machine can release from surface.
WARNING: Wear ear and eye protection when using this machine.
Machine use and care
1. When using the machine on non-horizontal surfaces, you must use cutting paste. Do not use
oil because the oil can drip into the motor unit;
2. While operating the machine, the annular cutter must be cooled and lubricated with high
quality cutting lubricants;
3. Always remove the slug from the annular cutter after each hole.
WARNING: The metal slug can be sharp and very hot!
4. Use clamps or other practical solutions to secure and support the workpiece to a stable
platform. Holding the workpiece by hand or against your body is unstable and may lead to
loss of control;
5. Do not use the machine when the switch does not turn it on or off. Any machine that cannot
be controlled with the switch is dangerous and must be repaired;
6. Disconnect the plug from the power source before making any adjustments, changing
accessories or storing the tool. Such preventive safety measures reduce the risk of starting
the tool accidentally;
7. Store your magnetic drilling machine out of reach for children and other untrained persons.
Tools are dangerous in the hands of untrained users;
8. Maintain your machine with care. Keep cutting tools sharp and clean. Properly maintained
tools, with sharp cutting edges are less likely to break and are easier to control;
9. Check for misalignment of moving parts, breakage of parts and any other condition that may
affect the machine’s operation. If you detect damage have the machine serviced before use.
Many accidents are caused by poorly maintained tools;

6
10. Only use accessories that are recommended by EUROBOOR for your machine model.
Accessories that are suitable for one machine may become hazardous when used on another
machine.

3. Preparation & adjustment
3.1 Assembly
WARNING: To reduce the risk of injury, turn machine off and disconnect from power source
before installing and removing accessories, before adjusting or changing set-ups or when
making repairs. Be sure all switches are in the OFF position. An accidental start-up can cause
injury.
Fitting the feed handles
1. Fit each of the three feed handles by screwing them into the hub in clockwise direction;
2. Tighten firmly by hand.
The handles are supposed to face slightly outward. Be careful not to cross-thread any of the
components.
Mounting the safety guard
The safety guard protects against chippings and accidental contact and must always be mounted
before operation.
1. Hold the guard in front of the magnet, align the slots in the guard with the holes in the
magnet;
2. Fit the screws into the holes located in the side of the magnet.
WARNING: Always use the safety guard.
Fitting the lubrication system
The lubrication system can be used for horizontal drilling applications
(the drill being used vertically).
1. Hang the coolant tank (A) on the coolant tank holder
2. Position and tighten the attachment pin (B)
3. Connect the coolant hose (C) to the fitting on the Gearbox.
Make sure the hose is connected fully and tightly.
4. To disconnect the coolant hose, press the blue ring on the
connection and gently pull out the hose
[Image 3-1]
Fitting the safety chain
1. Pass the safety chain through the frame grip opening;
2. Wrap the chain around the workpiece;
3. Securely close the chain using the lock.
WARNING: Always use the safety chain when drilling vertically and/or up-side-down. The
safety chain does not replace the magnetic force of the magnetic drilling machine: it is simply
used to secure against falling in the event of a magnet malfunction.

14
3.2 Prior to use
Please make sure that the contacting surface for the magnet is level, clean and rust free.
Remove any varnish or primer. When working on materials that are not magnetisable, suitable
fixation devices, obtainable as accessories from EUROBOOR, e. g. suction plate, vacuum plate or
pipe-drilling machine must be used. When working on steel materials with a material thickness of
less than 6 mm, the workpiece must be reinforced with an additional steel plate in order to
guarantee the magnetic holding power.
Check the machine for possible damage. Before using the machine, you must carefully check the
protective components or slightly damaged components to ensure they are operating perfectly and
as intended. Check that moving parts are in perfect working order, do not jam and check whether the
parts are damaged. All parts must be correctly installed and fulfill all conditions necessary to ensure
perfect operation of the machine. Damaged protective components must be repaired or replaced
according to specifications by EUROBOOR or any authorised EUROBOOR dealer.
DO NOT use under wet conditions or in presence of flammable liquids or gases.
DO NOT let children come into contact with the machine. Supervision is required when
inexperienced operators use this machine.
Electrical safety
The electric motor has been designed for one voltage only. Always check that the power supply
corresponds to the voltage on the rating plate.
Your EUROBOOR magnetic drilling machine is designed in class I (grounded) according to EN 61029-1.
Earth wire is required.
If the supply cord is damaged, it must be replaced by a specially prepared cord available at
EUROBOOR or your EUROBOOR dealer.
Extension cable
If an extension cable is required, use an approved 3-core extension cable suitable for the power input
of this machine (see technical data).The minimum conductor size is 1.5 mm² (for 220V) or 14 AWG
(Amperage Wire Gauge for 110V). The maximum length is 37 metre (± 100 ft).
WARNING: When using a reel, always unwind the cable completely!
Useful tips
–Try a few simple projects using scrap material until you develop a ‘’feel’’ for the magnetic
drilling machine;
–Let the machine run in for a period of 8 to 10 hours before starting with big operations. Do
not load the machine too much during this run-in period;
–Never use the machine with serious overload;
–Keep the machine clear from moisture at all times to protect the machine, yourself and
others.

15
4. Using the machine
WARNING: Always observe the safety instructions and applicable regulations.
WARNING: To reduce the risk of serious personal injury, turn the machine off and disconnect
the machine from power source before making any adjustments or removing/installing
attachments or accessories.
4.1 Control panel
The control panel is designed for maximum ease of use and safety.
1. Magnet switch
2. Motor switch
4.2 Two-way electromagnet
Make sure the magnetic drilling machine is placed on a smooth, clean, level and solid surface without
any objects or debris to guarantee maximum adhesion.
The workpiece must at least be 6 mm (1/4") thick for the magnet to stick and to drill safely. In case
the workpiece is between 3 mm (1/8") and 6 mm (1/4"), make sure to make a proper base to create
a good magnetic field as shown below.
[Image 4-1]

16
[Image 4-2]
The electromagnet will work best on surfaces of at least 10 mm (3/8") thickness.
When the electromagnet is not able to create a good enough magnetic field, this may be caused by:
-Surface not being flat;
-Workpiece is not magnetisable (e.g. aluminium);
-Workpiece is coated or painted;
-Workpiece is not thick enough.
2-Way magnet
This machine is equipped with a 2-way magnet function. At half of the magnetic force (600 kg or
1,323 lbs), the magnet sufficiently sticks to the surface to hold the machine in position while not in
use. More importantly, it consumes less energy, generates less heat and as a consequence the
magnet will last longer. Only with full magnetic force (1,200 kg or 2,645 lbs) the machine can be used
for drilling.
Using the 2-way magnet:
1. Place and position the machine on the workpiece;
2. To activate the magnet at half of the magnetic force, press the RED magnet switch. The
magnet switch will be lit (RED);
3. For full magnetic force, press the GREEN motor switch “I” (see next paragraph);
4. To deactivate the magnet, first press the RED motor switch “O” to return to half magnetic
force and then press the RED magnet switch again.

17
We want to point out that above mentioned precautions and indicator do not guarantee that the
magnet will not release from the material. EUROBOOR accepts no liability when it comes to the
magnet not functioning or functioning poorly.
Make sure that the magnet attaches tightly to the work piece before turning on the motor unit of the
magnetic drilling machine. EUROBOOR magnets have two coils; make sure that both coils are in
contact with the material. Do not connect any other machine to the same electrical outlet to which
the magnetic drilling machine is plugged into, as it may result in the loss of magnetic force.
Always use the safety chain included. Drilling above your head is extremely dangerous and is not
recommended. For the use of magnetic drilling machines on pipes, not-flat or non-magnetic
materials, we refer to our catalogue or our website www.euroboor.com where several vacuum
tightening systems, pipe clamping systems and tube machines can be found.
4.3 Switching motor on and off
The motor unit can only be switched ON when the magnet is activated. To switch the motor ON,
press the GREEN button with marking “I”. To switch the motor OFF, press the RED button with
marking “O”.
4.4 GYRO-TEC safety
This EUROBOOR magnetic drilling machine is equipped with GYRO-TEC safety functionality. It
features a gyroscopic sensor which detects acceleration and displacement in any direction.
Whenever the machine recognizes a sudden or unwanted movement the motor will be shut down
automatically by the machine’s electronics. This safety functionality offers protection to the user in
various circumstances, such as:
-Sudden loss of magnetic force while in operation;
-Excessive vibration caused by incorrect drilling procedure, worn-out cutting tools, etc;
-Sudden displacement of the workpiece to which the magnetic drilling machine is attached.
By the motor shutting down automatically, risk of damaging or hurting the machine, tools, workpiece
and operator is reduced.
Every time the motor is started, the machines electronics need a moment to run a systems check and
initiate the safety system. The GYRO-TEC safety feature engages 3 seconds after the motor is started.
It is very important to note that this functionality raises the safety level, but does not prevent the
operator from using the machine incorrectly. The operator should always follow instructions
described in this manual and take all necessary safety precautions.

18
4.5 Power protection
The power protection feature is two-fold; it consists of both power fluctuation protection and power
surge protection. Special safety components built into the electronics of the machine make it more
reliable in situations where power supply can be of varying quality due to factors:
-Around the workplace, for example caused by switching on high power or unreliable
electrical devices, a broken circuit breaker or faulty wiring;
-Outside the workplace, for example caused by an instable power grid or lightning.
A machine with this feature is able to cope with standard rated voltage and frequency fluctuations
ranging from:
-110 Volt to 137 Volt and 45 Hz to 65 Hz, or
-220 Volt to 240 Volt and 45 Hz to 65 Hz
reducing the probability of breakdown and minimising down-time and repair cost.
Power fluctuation protection
When the frequency is too high (above 65 Hz) or too low (below 45 Hz), the motor will not start. If
the frequency of the power supply falls outside the range during your drilling job, the motor will shut
off automatically. The machine will work again normally when the normal frequency has been
restored.*
Power surge protection
Beyond the rated voltage, a machine with this feature is able to cope with voltage spikes up to 4,000
Volt (1-2μs)*. Depending on the height of the spike, it may be necessary to replace built-in fuses, the
control unit or the power switch, but other valuable parts like the motor and magnet will be
protected.
*Disclaimer: Euroboor is not liable for any damage caused to the machine due to electrical
problems in the workplace. Above mentioned protection is not guaranteed in all cases of voltage
spikes and/or frequency fluctuations. Euroboor accepts no liability when it comes to the power
protection not functioning or functioning poorly.
In the situation of the motor being shut off automatically as self-protection, you should:
1. Shut off the magnet;
2. Disconnect the machine from the power source;
3. Fix the source of the problem, by either:
-Making sure the issues with the power source is fixed;
-Connect the machine to a different and reliable power source;
4. Continue using the machine as described in this user manual.

19
4.6 Carbon brushes
This machine is equipped with carbon brushes with two protection features. The purpose of both
features is to schedule timely service and avoid additional costs by unexpected downtime or
unnecessary part replacement.
Carbon brush wear indicator
On top of the motor housing you will find an integrated LED light. Under normal circumstances this
light is off. The LED light will start burning red when the carbon brushes are worn to a level where it
is advised to replace them.
Actual remaining operating time depends on the use of the machine, but can be up to 12 operating
hours. This makes it possible to schedule service of the machine and avoid unexpected downtime.
Automatic shut-off
As additional protection, when the carbon brushes are actually worn to a level where replacement is
needed, the motor will shut off automatically. This prevents the armature from being damaged.
During automatic shut-off, the carbon brush wear indicator is not lit.
For replacement of carbon brushes, see chapter 6. Maintenance.
4.7 Tool lubrication
Horizontal applications
In order to use the lubrication system, the tank must be filled with a cutting lubricant.
1. Make sure the flow regulator is closed;
2. Unscrew the cap;
3. Fill the container with cutting lubricant;
4. Screw the cap back on.
•Adjust the fluid flow as required using the flow regulator;
•Add more cutting lubricant when the shavings (metal chips) become blue.
Vertical and overhead applications
Dip the cutter in cutting paste or apply an appropriate spray.
WARNING: Do not use the lubrication system in vertical or overhead drilling applications.
Instead use EUROBOOR cutting paste or spray.
Make sure to use only suitable cutting lubricants. EUROBOOR offers a wide range of cutting
lubricants for all tool and material combinations. Proper lubrication will help you create better and
faster results, and extend the lifetime of your tools.

20
5. Working with drilling accessories
5.1 Annular cutters
Annular cutters only cut material at the periphery of the hole, rather than converting the entire hole
to shavings. As a result, the energy required to make a hole is lower than for a twist drill. When
drilling with an annular cutter, it is not necessary to drill a pilot hole.
WARNING: Do not touch the cutter or the parts close to the cutter immediately after
operation, as they may be extremely hot and cause burns to the skin. Ensure nobody is in the
work area where the metal core (slug) is ejected.
Drilling conditions
The ease with which material can be drilled depends on several factors including tensile strength and
abrasion resistance. Whilst hardness and/or strength is the usual criterion, wide variations in
machinability can exist among material showing similar physical properties.
The drilling conditions are dependent on requirements for tool life and surface finish. These
conditions are further restricted by the rigidity of the tool and the workpiece, lubrication and
machine power available. The harder the material, the lower the cutting speed.
Some materials of low hardness contain abrasive substances leading to rapid cutting edge wear at
high speeds. Feed rates are governed by rigidity of set-up, volume of material to be removed, surface
finish and available machine power.
Drilling a hole
Now that you have read the information and safety recommendations above, you are ready to
actually start drilling. Follow these 12 steps for best drilling result:
1. Install the annular cutter:
-Place the pilot pin into the cutter;
-Align the flat faces on the cutter shank with the screws in the tool holder;
-Make sure the cutter shank is entered fully and correctly;
-Tighten the screws with the provided Allen key;
[Image 5-1]
2. Precisely mark the center of the hole;
3. Use the pilot pin to position the machine in the correct position, with the tip of the pilot pin
to meet the marked center of the hole;
