understood this manual, specifically the “General safety instructions” and ‘’Specific safety
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
will enable 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;
8. Always use supplied safety chain during any work on non-horizontal surfaces. Magnetic
drilling machine can release from surface;
When using this machine, you MUST wear ear and eye protection.
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.
Caution; the slug may be 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;
10. Only use accessories that are recommended by Holemaker Technology for your machine
model. Accessories that are suitable for one machine may become hazardous when used on
another machine.

WARNING: Always use the safety chain when using machine vertically and/or up-side-down.
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 HMT, 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 HMT or
any authorised HMT 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 HMT 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 HMT or
your HMT 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; the maximum length is
30 meter. When using a cable reel, always unwind the cable completely.

4.2 Electromagnet
Make sure the magnetic drilling machine is placed on a smooth, clean, level and solid surface without
any objects or debris in between to guarantee maximum adhesion.
The workpiece must be at least 5 mm thick for the magnet to stick, but minimal 3 mm thick to hold
the weight of the machine and to drill safely. In case the workpiece is between 3 and 5 mm, make
sure to make a proper base to create a good magnetic field as shown below.
[image 4-2]
The electromagnet will work best on surfaces of at least 10 mm thickness.
The electromagnet may not be able to create a good enough magnetic field. Causes may be:
-Surface not flat
-Workpiece not magnetisable (e.g. aluminium)
-Workpiece coated or painted
-Workpiece not thick enough
In this situation the magnet indicator will light up RED. Make sure to solve any of these matters
before proceeding in any way and creating unsafe situations.
Using the magnet:
1. Connect the machine to the mains/work piece
2. To activate the magnet, press the RED magnet switch
The magnet switch will be lit (RED)
The LED indicator lights up GREEN when generated magnetic force is sufficient
3. To deactivate the magnet, press the same switch again

17
WARNING: Do not use this machine when LED indicator is RED. Magnet may not generate
sufficient attachment force
We need to point out that this is only an indication and not a certainly that the magnet will not
release from the material. HMT accepts no liability ensuring from the magnet indicator 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. HMT magnets have 2 coils; make sure that both coils are in contact with
the material. Do not connect any other machines to the electrical outlet 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 brochure or our website www.holemaker-technology.com pipe clamping
systems are mentioned.
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 Tool lubrication
Horizontal applications
In order to use the lubrication system, the tank must be filled with a cutting fluid or oil
1. Make sure the flow regulator is closed
2. Unscrew the cap
3. Fill the container with cutting fluid or oil
4. Screw the cap back on
•Adjust the fluid flow as required using the flow regulator;
•Add more cutting fluid if 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 cutting paste or HMT SPEEDLUBE lubricant spray
Make sure to use only suitable cutting oil or fluid. HMT offers a wide range of cutting lubricants for
all tool and material combinations. Proper cooling will help you create better and faster results, and
extend the lifetime of your tools.

18
5 Working with operation tools
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 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 work piece, 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 explanatory 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 (1)
-Tighten the screws (2)
[image 5-1]

19
2. Precisely mark the centre of the hole
3. Use the pilot pin to position the machine and in the correct position, with the tip of the pilot
pin to meet the marked center of the hole.
4. Switch on the magnet and verify that the drill is in the right position and that the machine is
pushed tight against the work piece.
5. If your machine is equipped with a auto coolant system, put open the valve to release the oil.
If your machine does not have an auto coolant system, fill the holes of the spindle with oil.
6. Switch the motor on at and allow it to run at the required speed.
7. Turn the arms to start drilling. Apply only a slight pressure when the annular cutter touch the
metal. Do not push the annular cutter with force into the metal.
8. Apply a regular pressure while drilling. The drilling performance does not improve by putting
more pressure on the tool. Too much pressure will overload the motor and your annular
cutter will be worn sooner.
A continuous, non-discoloured iron swarf is a sign of correct drilling speed and a well-
cooled, sharp cutter. Let the cutter do the job and give it time to cut the metal!!!
9. Adjust the oil supply when necessary, if your drill does not have an auto coolant system, stop
drilling regularly, refill the holes of the spindle and continue drilling.
10. Apply less pressure when the drill cuts through the material. The slug will be pushed out of
the cutter by the pilot pin.
11. Turn the arms to put the motor in highest position and switch off the motor unit.
12. Remove the burrs, metal chips and clean the cutter and surface without getting injuries.
Caution: The metal piece drilled out can be sharp and very hot!!

20
5.2 Twist drills
1. Fit the twist drill
a. Straight shank twist drills
Use a Weldon to drill chuck adapter (such as HMT Weldon to ½”x20 UNF) to fit a drill
chuck and straight shank twist drill accordingly.
