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 be achieved only with optimal
tooling. Milling cutters are designed and manufactured specifically for use with these machines and
offer a whole range of advantages such as 4 inch diameter holes through more than 2 inch steel, in
one pass and with precision not otherwise attainable without heavy stationary equipment.
The COMPACT 75 machine is capable of drilling and reaming holes up to 75 mm diameter
and 76 mm depth with a precision achievable previously only in a workshop.

5. OPERATING INSTRUCTIONS
The drilling machine has a spindle with Morse Taper MT3 to use twist drill (by using the
reduction adapter if necessary) and annular cutters. Arbor mark AMT is mounted in spindle conical
taper to fix annular 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 (Drawing No. 3).

8. MAGNETIC DRILLING MACHINE START UP
The machine is supplied in a metal box with complete standard equipment.
Before first drill:
•Steel elements of the drilling machine are protected for transit and storing with grease film. Before
first start up of the machine all grease should be removed. This especially applies to Morse Taper.
•Before each use all handles should be screwed into pinion.
Before setting the machine on an item make sure that:
•Substrate is a steel and ferromagnetic (some of stainless steel or acid-proof or do not conduct the
magnetic flux);
•Thickness of work piece is at least 10 mm (3/8”);
•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.
Preparation the machine for drilling:
1.Set the drilling machine on the surface of the element which hole is to be drilled.
2.Accurately and securely attach the drill spindle in the nest (see 0).
3.Plug in the drilling machine accordance to the requirements (see 0).
4.Set the axis of the spindle exactly over the place of drilling (the tool is over the centre of the hole).
5.Turn the magnetic base ON.
Prior to use!

Preparation for cutting
1. Place the drilling machine on the working surface.
2. Secure the milling cutter firmly and accurately in the spindle socket
3. Fill the bottle of the cooling system with the cutting fluid.
4. For drill and milling cutter cooling during drilling it is recommended to use cutting fluids available
on the market in the condensed form. It is also possible to use emulsion formed by mixing water
and drilling oil.
Using pure water as a cutting fluid is not allowed.
5. Check operation of the cooling system. To do this loosen bottle nut, set the knob of the small valve
to position ”ON” to initially bend the pilot placed inside the milling cutter by lowering the drive on its
guides. The fluid will fill the system and after short period it will start flowing out from the inside of
the drill.
CAUTION: Cooling system works according to gravitation. Due to
this in another drilling position than vertical the cooling liquid must be
provided manually.
6. Define the direction of the spindle rotation.
7. Set proper rotational speed according to the type of the tool and working material.
8. Connect the drilling machine to electric network according to
9. Set the axis of the spindle right above drilling point (in the case of milling cutter the end of the pilot
helps with alignment).
10. Turn the mounting of the electromagnetic base on.
To be sure check if electromagnetic base is properly secured, in the case of horizontal
works, works on ceilings and on heights secure it by using chain or safety belt.
Preparation for tapping
1. Using a MT3 wedge (included in a set) put the milling head holder (AMT3-U-19/3-3, included in
the set) out of the drilling machine spindle.
2. Mount the tap socket with 1- or 2-axis compensation into the spindle (not included in the set).
3. Choose the right socket adapter to match tipping diameter. Mount tap no. 1 into the adapter and
place it in the compensation socket.
4. In the case of using taps with conical handle, mount it directly into the spindle or by using reducer
with MT3 cone.

Types of a ground material
As shown on the graphs (Drawing 4) 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, and 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 2-step
reducing gearbox of a motor rpm. A general dependence between drilling diameter and drilling speed
is shown in graphs (drawing 5), 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.
Cooling agent is fed gravitationally from a coolant bottle through an arbor to an inside of the metal
cutter. For on-a-wall and on-a-ceiling positions special cooling pastes have to be used.

Electromagnetic base clamping force control system
This system for security reasons is an integral part of each drill type PRO. 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 enabling 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, and
excessive wear of the lower part of the electromagnetic base.
If there is 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.
Working in difficult areas
While working in difficult access areas as well as left-handed operator, there’s a possibility to
change location of the pinion with spoke handles to the other side of drilling machine.
Additional option of machine COMPACT 75
Drilling machine COMPACT 75 is equipped with additional special function which enable to move
upper part of machine about 15 degrees and 15 mm front/back using allen key s=10, without moving
the electromagnetic base.
