attachment method used with the diamond-tipped segments of the REMS
Universal diamond core drilling crown has been modified so that smal-
ler diameters can also be drilled efficiently with the REMS Picus S1.
The turning speed of the REMS Picus S3 can be selected by means of a
three-speed stepped drive to ensure that in concrete it always operates
within the optimum drilling speed range. The correct speed can be taken
from the machine rating plate (Fig. 7) of the REMS Picus S3. The first co-
lumn of the table shown there covers speeds 1 to 3, the second column
shows the corresponding turning speeds, the third column the core bit dia-
meters for masonry and the fourth column contains core bit diameters for
steel-reinforced concrete. It shows, for example, that a Ø 102 mm core-
drilling operation in masonry should be carried out in third speed, while
drilling into steel-reinforced concrete requires the use of first speed.
The turning speed of REMS Picus S2/3,5 can be selected by a 2-step
switching gear so that it always drills in an optimum area. The right ge-
ar can be read from the rating plate (Fig. 8) of REMS Picus S2/3,5. The
table there shows gears 1 and 2 in the first column and the correspon-
ding speeds in the second column and the drill crown diameters for ma-
sonry and steel-reinforced concrete in the third column.
Important: Wait for the machine to come to a halt before engaging the
transmission. Never try to do this during operation or outflow. If you can-
not engage a particular speed, turn the handle grip (39) and rotate the
drive spindle/diamond core drilling crown by hand at the same time. Pull
out the mains plug first!
2.3. Universal diamond core drilling crowns REMS UDKB
The cutting characteristics of the diamond core drilling crown are de-
termined by the quality of the diamonds, the particle-size and shape of
the diamonds, and also by the bonding agent – the metal powder in
which the diamond particles are set. Users who need to carry out a va-
riety of core-drilling operations should keep a range of diamond core
drilling crowns of different sizes to hand in order to optimise the cutting
process. It is often only possible to ascertain onsite which diamond core
drilling crown is ideal, in terms of cutting performance (operating speed)
and service life, for a particular drilling task. You may even have to contact
the manufacturer of the diamond core drilling crown on various occa-
sions in order to find out which bit should be used.
REMS has developed the Universal diamond core drilling crown for use
in common drilling operations. These bits are universally applicable for
both dry and wet drilling, either manually-controlled or with drill upright.
The connection thread of the REMS Universal diamond core drilling
crown UNC 1 1 / is compatible with the REMS Picus S1 and REMS Picus
4
S3, and with suitable drive units from other suppliers. If the connection
thread proves to be incompatible with the drive unit, special adapters
are available as accessories (22).
2.3.1. Fitting the diamond core drilling crown
Unplug from the mains power supply. Screw the selected diamond core
drilling crown onto the drive spindle (11) of the drive unit, and lightly
hand-tighten. It is an advantage to insert the quick-release ring (art. no.
180015) between the diamond core drill crown and the drive spindle.
There is no need to tighten it with a wrench. Note that the threads on
the drive spindle and diamond core drilling crown must be clean.
2.3.2. Removing the diamond core drilling crown
Unplug from the mains power supply. Use an SW 32 wrench to hold the
drive spindle (11) and an SW 41 wrench to loosen the diamond core
drilling crown (48).
Always unscrew the diamond core drilling crown from the drive unit when
the drilling task is finished. With wet-drilling operations in particular, there
is also a danger of the diamond core drilling crown becoming corroded,
making it difficult to remove.
Important: The casing pipes of the diamond core drilling crown are not
hardened. Hitting (with tools) and impact (during transport) on the casing
pipe will lead to damage that is likely cause the diamond core drilling
crown and/or drilling core to become seized. The diamond core drilling
crown may then be rendered unusable.
2.3.3. Sharpening the diamond core drilling crown
REMS diamond core drilling crowns are supplied ready-sharpened. If
feed pressure is kept at the correct level, the diamond-tipped segments
will sharpen themselves. Incorrect feed pressure can lead to the dia-
mond-tipped segments becoming „polished", which causes their cutting
performance to diminish. If this occurs, use the diamond core drilling
crown to drill 10 mm to 15 mm into sandstone, asphalt or a sharpening
stone (available as an accessory) in order to sharpen the diamond-
tipped segments once more.
2.4. Manually-controlled dry boring REMS Picus S1 and
REMS Picus S3
Secure the holder-up (12) to the drill collar (13) of the drive unit.
Important: Never carry out manually-controlled drilling without first
fitting the holder-up. DANGER OF ACCIDENTS!
The water supply system (15) gets in the way of manually-controlled dry
boring, and it should therefore be disconnected. Remember to shut off
the water inlet with its sealing cap (14) to prevent dust from getting into
the machine.
Important: Always wet drilling for steel-reinforced concrete!
2.4.1. Tapping tool
Manually-controlled tapping is made considerably easier, thanks to the
REMS tapping tool (49). This is fitted with a conventional hardened-
metal Ø 8 mm masonry bit, which is secured in place with an SW 3 hexa-
gon socket head wrench. The G
tool into the spindle of the drive unit, where it is gently tightened with an
SW 19 wrench.
2.4.2. Dust extraction REMS Picus S1 and REMS Picus S3
We recommend the use of a dust extraction system to remove drilling
dust from the machine during core-drilling operations. This consists of
the REMS suction rotor for dust extraction (available as an accessory)
and a fine-dust suction extractor designed for industrial use. The suc-
tion rotor (46) is screwed to the drive spindle (11) of the drive unit using
the G 1 / connector. The combined annular core bit connector (47) on
2
the opposite side permits the fitting of diamond core drilling crowns with
female thread UNC 1 1 / and the attachment of the tapping tool (49).

If the dust produced by dry boring is not removed, the diamond core
drilling crown may overheat and suffer damage. There is also a danger
of the compressed drilling dust in the gap causing the diamond core
drilling crown to become blocked.
2.5. Wet boring
Optimum drilling performance will only be achieved if the diamond core
drilling crown is provided with a constant supply of water. This keeps the
diamond core drilling crown cool and allows drilled-out material to be
swilled from the bore hole. To connect the water supply system (15), re-
move the cover (14) and attach the water supply system with the fillister
head screw supplied. The quick-action coupling with water shutoff de-
vice should be fitted with a
exceed 4 bar.
If there is no direct water connection available, water throughflow can
be achieved using the water pressure tank (51) (accessory). Be aware
that there is sufficient water flow.
A water extractor unit (44) (accessory) should be used if required. This
consists of a water-collection ring and a pressure ring which is secured
to the foot of the boring trestle (1). The water-collection ring is to be
connected to a wet-suction extractor designed for industrial use. The
size and shape of the rubber gasket (45) in the water-collection ring must
exactly match the diameter of the annular bit.
2.6. Boring with a drill upright
Good results can be obtained by operating with a drill upright. The pur-
pose of the drill upright is to guide the drive unit. Its power transfer rack-
and-pinion drive system ensures both hole-tapping with „feel" and po-
werful infeed of the diamond core drilling crown. REMS Picus S1 and
REMS Picus S3 can be mounted optionally on the REMS Simplex or
REMS Duplex drill stands. REMS Picus S2/3,5 must be mounted on
REMS Duplex 300.
In the case of the REMS Simplex, the feed slider (2) supplied with the
unit must be inserted into the boring trestle (1), along with the feed lever
and clamping angle, and advanced by turning the feed lever (4). The
two reverse adjustment screws (5) should also be screwed in.
With the REMS Duplex, the clamping angle (10) and short fillister head
screws (supplied with the unit) should be screwed to the feed slider (2).
