1. GENERAL INFORMATION
Portable drilling machines with electromagnetic bases are fast becoming very
universal power tools not only at steel fabricating workshops or steel building sites
but also at every factory maintenance workshop, truck manufacture & repair
company, military equipment service, onboard ship maintenance shop etc.
But full advantages of electromagnetic drilling machines can only be achieved
with optimal tooling. Milling cutters are designed and manufactured specifically for
use with these machines and offer a whole range of advantages such as 3 inch
diameter holes through more than 2 inch steel, in one pass and with precision not
otherwise attainable without heavy stationary equipment.
The MAGBEAST HM40 machine is capable of milling 40 mm holes through 2
inch plate what is totally unique for an electromagnetic drill of that size and weight.
The MAGBEAST HM40 is equipped with a powerful verified for many years of
exploitation drive and electromagnet with field control system.
Before you start work with the machine, please read these instructions
carefully. Take special note of safety recommendations.

Important rules of safe use of drilling machine
1) Before attempting to work with the machine check condition of electrics
including power cord and plug.
2) The drilling machine should be connected to an installation equipped with
protection circuit (neutral or ground) and protected with a 16 A fuse for 220V
and 32 A fuse for 120V. When used on building sites, it must be supplied
through a separation transformer made in the second class of protection
3) Machine can be used outdoors, but is not weatherproof. Do not expose to rain,
snow or frost.
4) Machine should not be used on: rusty surfaces, steel plates covered with thick
paint, uneven surfaces, or next to a welding machine.
5) In all cases always use a safety chain/strap /see drawing 1/. The safety chain
mustn't be loose! To avoid this situation the safety chain should be wrapped
around the element it is hooked to.

Safety chain can also secure the drill through
the handle.
6) Do not use the machine in explosive environmental areas.
7) Do not start work if the machine has excessive play on guide slides.
8) Always wear safety goggles and ear protection.
9) Do not remove metal chips with bare hands.
10) Do not touch the spindle and the cutter during work.
11) Tools must be fastened firmly. When a milling cutter is used, check before start
of work if tool holding screws are screwed tight.
12) It is not permitted to use blunt of damaged tools.
13) Do not use milling cutter without pilots, and arbors without ejection spring.
Do not touch or replace the tool with power source on –while
electromagnetic base is being used.
14) Use tools recommended in Operator’s Manual only.
15) After use, always clean drilling machine from metal chips and coolant.
16) Always unplug machine from power supply during any work on the machine.
17) Before each use the machine should be checked for the presence of damage
and the proper and consistent use. Check whether any of the parts are broken

18) In the case that the machine falls on a hard surface, from a height, is wet or is
subjected to other unfortunate events that could affect its technical state - work
should be terminated immediately and the machine should be sent to service for
inspection as soon as possible.
Caution should be taken when machining plates with thickness lower
than 10 mm (0.4’’) because adhesion force depends on material thickness
and is significantly lower for thin plates. The whole surface of machine base
must stick to working material. Before every positioning, wipe working
surface with coarse-grained sandpaper.
Please keep all recommendations.

4. START UP AND OPERATION
4.1 Cutters and optional equipment features.
This drilling machine’s spindle has a Weldon Shank type socket 3/4” or
19,05 mm and is specifically designed for use with milling cutters.
Milling cutter (2) is located inside arbor body (1) and is fastened with screws
(3). While fastening the cutter in the socket, be aware that screws should be screwed
tight so that they could not come unscrewed. It is important to position the cutter in
relation to the socket in such a way that fixing flats on the cutter shank are positioned
opposite to the fixing screws (3). Both fastening screws(3) should be used to fasten
the cutter. Pilot (5) is located inside the cutter. It makes it easier to position milling
cutter over centre of a planned hole. During drilling as the cutter goes deep into steel,
the pilot moves back into the arbor body and tightens discharge spring (4). That
spring ejects slug which is a by-product of milling a hole with a centre free cutter.
Basically milling cutters are designed to make through holes. On occasions when
there is a need for an overlapping hole pilot should not be used.

4.3 Before you cut
Before positioning the machine on the work piece always make sure that:
-work piece is made of steel;
-thickness of work piece is at least 3/8” (10 mm)
-surface of steel under the magnet is flat
-wipe, brush or sand down clean surface where you intended to place the
drilling machine, so that you remove rust, paint, dirt etc which would reduce adhesive
power of the electromagnetic base.
Install drill bit, milling cutter or other tooling such as tap or reamer in the machine
before plugging it into mains. Then plug it in and position where you wish to use it.
Place the machine so that the tool is over the centre of the hole you intend to make
and turn the magnetic base ON.
Prior to use always make sure that the machine is secured from falling
down with original chain (as described in paragraph 4 “Important rules of safe
use of drilling machine”).
4.4 Cutting
- Cutting lubricant is highly recommended when cutting with twist drill and
annular cutters.
It’s allowed to use of emulsions formed from a mixture of water and drilling oil.
Do not use clean water for cooling and cutting lubricant.
The cooling system is an integral part of the machine and should always be used.
(see point 4.9)
Warning: The cooling system can only be used when drilling machine is
in vertical position. In other positions additional external source of cooling
should be used, for example: a coolant bottle with a long nozzle or JEI Turbo
Endurance + spray/paste
-Check working condition of cooling system. Open coolant reservoir’s tap and
apply pressure on the pilot by turning spokes counter clockwise. As the pilot starts to
sink into the cutter, the cutting lubricant should start to run down cutters inner wall. If
there is no liquid flowing down check if the tap is fully opened. It may take a few
seconds for cooling liquid to fill the whole system.
-Turn the motor on.

Bring the cutter gently into contact with the work piece and slowly start to
apply pressure on the cutter.
Making a hole with a milling cutter should ideally be done in one pass. It
makes the cutter work better and easier to eject the slug after the hole is completed.
If you experience slugs getting stuck inside a cutter after hole is complete try to
reduce pressure on the cutter or use different coolant. Do not allow excessive swarf
build up around the cutter and arbor.
WARNING: when the milling cutter goes through the material the
slug can be pushed out often with considerable strength.
Pay attention to avoid injury.
-After a hole is made the cutter should be withdrawn back and both the motor
and the electromagnet should be switched OFF.
-When work with the machine is finished the power cord should be
disconnected from the power source, the machine should be cleaned up from swarf,
coolant etc and the cutter should be removed and cleaned.
-The tool should be removed from drill chuck before inserting to the toolbox.
4.5. Types of a ground material
As shown on the graphs [Drawing 6] magnetic clamping force of the
electromagnetic base to the ferromagnetic ground depends on its magnetic
properties. Steel with increased carbon content and some other alloying ingredients
has lower magnetic permeability, what causes a decrease in the clamping force. Also
a thickness of a work piece, on which the drill is placed, is significant.
Maximum clamping force of the electromagnetic base to a 5 mm thick work
piece surface is only about 25% of a clamping force obtained from a smooth,
plane, 22 mm thick standard plate.
If such thin ground material does not bow, one can try to carry out drilling
of a hole, although with keeping the strictest precautions. Particularly a
magnitude of a pushing force on a feed handle should be very limited.
Appropriate rpm should be adjusted depending on if drilling would be carried
out with a drill bit, or with trepan type metal cutter and a metal cutter’s diameter. A
drive is equipped in mechanical 1-step reducing gearbox of a motor rpm. A general
dependence between drilling diameter and drilling speed is shown in drawing 7,
detailed guide is supplied by manufacturer of used drilling tools. The graph is just a
general guide and the shown dependence applies to average structural steel. One

should remember that during the drilling a cooling has to be used in a form of oil
emulsion in a titer of 5 -10%.
Cooling agent is fed gravitationally from a coolant bottle through an arbor to an
inside of the metal cutter. For horizontal and overhead positions special cooling
pastes have to be used.
4.6 Electromagnetic base clamping force control system
This system for security reasons is an integral part of each drill type
MAGBEAST. It works by constant monitoring of the electromagnetic force base
adhesion value to the substrate. In the case of fall the force value below to guarantee
safe operation of the machine, the system automatically switches off the drive drill. It
also does not allow to enable drive which does not guarantee the proper clamping
force. Clamping force depends on: type and thickness of substrate, thick coatings on
the substrate, rust or other contaminants, lack of flatness of the substrate, excessive
roughness of the surface, excessive wear of the lower part of the electromagnetic
base.
If there’s a problem to enable drive after turn on of the electromagnetic base
so drive works only after START button is pressed, and after release the drive is off -
it means that system works properly. The system didn’t allow to for further work due
to insufficient clamping force drills.
4.7 How to use the special functions
There are many causes which can reduce magnet holding force. These can be:
insufficient work piece thickness, paint coating, rust or dirt, uneven and rough
surfaces, extensive wear of the magnets bottom surface etc.
If after turning drills electromagnet ON the motor would not start it can be
caused by machines safety system which had detected insufficient magnets
holding power. Motors operation can then be executed by holding the green
Start “I” button pressed continuously. After release of the Start button the
motor will stop. To eliminate this situation it is necessary to improve magnetic
properties of the work piece or recondition the magnetic base.
To operate this machine you should push on the main switch in position ”I”. Then
you should turn on the green button ”I” to turn on the motor. To stop the motor you
should push on red button “O” (It causes the motor off, the magnet still holds). To
move on the machine to drill in another place you should stop the motor and then
push on the main switch in position “I”.
