2 Description of the machine
2.1 Features
The Pentruder Modular Drill System MD1 is a versatile and powerful drilling system. The 4-speed MG41
gearbox gives the system a very smooth and efficient run and with two exchangeable spindle units it offers
a wide speed range for different sizes of drill bits.
Quick disconnect couplings reduce the set up time. Small and big drill bits can be drilled in a shorter time
than anyone thought possible.
Pentruder MD1 drill system can be driven by a 15, 18 or 22 kW HF-motor. Together with the MG41
gearbox and a ST2 or ST3 spindle unit and a Pentpak HF-power packs up to 1200 mm big holes can be
drilled easily and efficiently.
Pentruder MD1 HF-drilling machine can either be built on the wall saw track (MCCS) or on the 70 mm
column system.
2.2 Modules MD1
•MG41 4-speed gearbox
•ST2 / ST3 (QDC-)Spindle unit for MG41 (quick disconnect coupling for drill bit optional)
•ERMD1 Extension Adapter for MD1 (Extends capacity by Ø 190 mm per adapter and up to 3
pcs can be used.)
MG41 ST2/ST3 ERMD1
2.2.1 MG41 Gearbox
The Pentruder drill system has a 4-speed gearbox to offer a wide speed range for various drill bit
diameters. Performance and safety is increased as the spindle speed cannot be increased over the
adjusted speed during drilling.
2.2.2 ST2 / ST3 (QDC-)Spindle unit
The concept with exchangeable spindle units makes it possible to get a very wide spindle speed range with
only one drilling machine. The ST2 spindle unit gives lower spindle speeds than the ST3 spindle unit. See
chart on page 27 for spindle speeds. The spindle units can be ordered with or without Quick Disconnect
Coupling (QDC) for the drill bit.
2.2.3 ERMD1 Extension adapter MD1
When drilling big diameter holes over Ø 600 mm (23.6”) an extension adapter must be used to extend the
distance between drill column and spindle, giving more clearance for bigger diameter drills. Each adapter

Operator’s manual for the Pentruder MD1 HF-drilling machine and Pentpak - Original instructions Page 4
extends the drill unit 90 mm (3.5”) further away from the column, i.e. gives additional clearance for a 180
mm (7”) bigger drill bit. Up to 3 pcs can be used together.
2.3 Main drive HF-motor and adapter HFMR-MG41
•HFR415, 15 kW HF-motor, 400 V
•HFR418, 18 kW HF-motor, 400 V
•HFR422, 22 kW HF-motor, 400 V
•HFMR-MG41 Adapter for HF-motor on MG41
The same HF-Motor as is used for drilling is also used for wire sawing and wall sawing. We especially
recommend the 15 and 18 kW HF-motors for drilling.

•Mounting and dismounting of the drilling unit and drill bit may only take
place when the drill motor is disconnected from the power pack by
removing the 400V power cable.
•The power pack is water cooled and must be drained from water when
the ambient temperature is in the proximity of or below 0 degrees
Celsius.
•The electric motor of the power pack is water cooled and the water
pressure must therefore be limited to max 5 bar. The incoming water
supply may only be connected to the lower connection on the power
pack. The quick disconnect couplings may not be replaced with
couplings that are not fully open when disconnected.
•Always lift the drill unit ergonomically correct. The Pentpak is not
provided with hooks for lifting. Should this unit need to be lifted with a
crane, this should only be done after permission and instructions have
been given by a person responsible for safety on the site. Contact your
sales agent for instructions on how the lifting can be done in the best
way.
•The base plate must always be securely anchored to perform safe
drilling.
•Never run the drill unit without water cooling. The seals are quickly worn
and water leak can occur. Should the cooling water seize to function,
stop the machine immediately.
•Before drilling is commenced all persons involved must know how the
emergency stop button is working.
•Remember always to cover drilled holes so that no person falls down
and hurts himself.

•Should the drilling machine fall down from the ceiling it could cause
severy injuries. Keep away from the working area of the drilling machine.
•Don’t use any extension or lever to get a higher feeding power.
•A heavy core in a drill bit which rotates outside of the drilled how can
lead to heavy vibrations so that the drilling machine can come loose
from the anchor. Stop the drill bit shortly before it comes out of the drilled
hole.
•Re-bars which have been cut off can be stuck between the core and the
drill bit and block and/or damage the drill bit. Before the drilling is
commenced, make sure that no segments are left in the drilled hole.
•Should the drill bit get stuck, turn off the drill motor and unplug it. Use a
wrench to move the drill bit forwards and backwards until it is
disengaged and can be pulled out of the hole.
•When drilling upwards, make sure the core cannot fall down by securing
it properly. Rope off the working area.
•Only change gear when the main HF-motor is stopped.
•The power pack must only be operated when in an upright position.

4.4 Mounting of drill stand 70 mm column system
4.4.1 Assembly of BE base plate- and CN F/M-70 column
Assembly of BE2 base plate- and CN 0.5 F/M-70 column.
1. Secure the base plate to the floor or wall with an expanding anchor and minimum 12 mm (1/2”)
bolt. Be observant on what material the base plate will be mounted on. For safety it is important
that the base plate is properly secured. If mounted on brick or light concrete we recommend to
secure the base plate with through bolts.
2. When drilling with large drill bits we recommend using two anchors of M16 size to fasten the base
plate.
3. Fit the column on the base plate.
4. Pull out the support legs and check with the level to see that the column stands vertical and steady.
If not, adjust with the screws on the support legs until the column stands correctly.
5. To mount the column on the base plate, or a pivoting head, or to join two columns, an eccentric bolt
is inserted in the hole in the column, and tightened clockwise with an ½” knuckle bar or ratchet.
6. The column is locked by turning the eccentric bolt Clockwise.
7. To release the column, the eccentric bolt is turned Counter Clockwise until it lifts from the cone, the
eccentric bolt is removed and the column can be removed.
WARNING!
•The base plate must be securely fastened to perform safe drilling
•Be careful to clean the mounting hole for the base plate with water or air
before fitting an expander bolt.

4.4.2 Back support for 70 mm column
For most drill operations a back support is needed to give greater stability, for example when drilling with
high pressure and high load. The back support should always be used to stabilize the column, especially
where circumstances are hard and demanding.
4.4.3 Mounting of carriage CE1 on 70 mm column
CE1-70 carriage with PT feed unit CE1-70 carriage with friction brake
1. Loosen the socket on the hydraulic feed unit or the 19 mm Hex bolt on the friction brake.
2. Put the carriage on the column.
3. Adjust the height of the carriage by turning the feed shaft with a knuckle bar.
4. Tighten the socket on the feed unit or the hex bolt on the friction brake until the carriage doesn’t
slide down the column.
5. For optimum preload of the rollers on the column, the rear rollers should be adjusted using a ½”
spanner and a 15 mm wrench. Adjusted correctly, this eliminates all play between the carriage and
the column. Do not set the rollers too hard. The result will be premature wear of the column.
6. Lock the eccentric shafts for correct pre load of the rollers, by tightening the screw with a 15 mm
wrench.
The drill unit (gearbox, spindle unit and hydraulic motor) can mounted on the carriage with the drill spindle
pointing in both directions along the column. Note that the drill unit can be mounted in two positions along
the carriage.

Important!
•Be observant so that the eccentric bolt doesn’t slip out of the column
when the column is put on the pivoting head. It MUST be completely
flush with the column side face.
•When the adjustable male-coupling shall be adjusted please make sure
the teeth are correctly in mesh.
•When the pivoting head is mounted, be sure that the locking screws are
tightened to give enough friction between column and pivoting head, to
keep the pivoting head from sliding down the column in an uncontrolled
way.
