WARNING
Wait for the machine to come to a halt before engaging the transmission!
Never try to do this during operation or outfl ow. Pull out the mains plug if a gear
cannot be switched! At the same time, turn the switch handle (39) and move
the drive spindle/diamond core drilling crown by hand.
2.3 Universal diamond core drilling crowns REMS UDKB, REMS UDKB-LS
REMS UDKB – inductively soldered and resolderable
REMS UDKB-LS – laser welded and high temperature resistant
The cutting characteristics of the diamond core drilling crown are determined
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 parti-
cles are set. Users who need to carry out a variety 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 fi nd 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 1¼ is compat-
ible with the REMS Picus S1, REMS Picus S2/3,5, REMS Picus S3 and REMS
Picus SR and with suitable drive units from other suppliers. If the connection
thread proves to be incompatible with the drive unit, special adapters are avail-
able as accessories (22).
2.3.1 Fitting the diamond core drilling crown
WARNING
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 ((54) accessory art. no.
180015) between the diamond core drill crown and the drive spindle. Firm
tightening with an open-ended wrench is not necessary. 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
WARNING
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 fi nished. With wet-drilling operations in particular, there is also
a danger of the diamond core drilling crown becoming corroded, making it
diffi cult to remove.
NOTICE
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 Universal diamond core drilling crowns have roof-shaped diamond
segments and do not have to be sharpened in the as-delivered state. At the
right thrust pressure and possibly by adding water, the diamond segments
sharpen themselves. Unsuitable thrust pressure as well as dry drilling in concrete
leads to the diamond segments being "polished" and no longer being able to
cut. If this occurs, use the diamond core drilling crown to drill 10 mm to 15 mm
into sandstone, asphalt or a sharpening stone ((55) accessory art. no. 079012)
in order to sharpen the diamond-tipped segments once more.
2.4 Manually-controlled dry boring REMS Picus S1, REMS Picus S3 and REMS
Picus SR (fi g. 4)
Secure the holder-up (12) to the drill collar (13) of the drive unit.
WARNING
Only use the tool held by hand with the brace (12) fi tted (danger of injury)!
Never perform hand-held dry drilling with REMS Picus SR in stage 1. The
resulting high torque can lead to injury.
Inhalation of the dusts produced by dry drilling is harmful to the health. Observe
the national regulations. It is recommended to use the suction rotor ((46) acces-
sory art. no. 180160) and a safety vacuum cleaner/dust extractor of dust class
M e.g. REMS Pull M (Art. No. 185501) with suitable fi lter (observe the operating
instructions of the safety vacuum cleaner/dust extractor).
CAUTION CAUTION
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.
NOTICE
Always wet drilling for steel-reinforced concrete!
2.4.1 Tapping tool for REMS Picus S1, Picus S3 and Picus SR
Manually-controlled tapping is made considerably easier, thanks to the REMS
tapping tool (49). This is fi tted 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 ½ thread is used to screw the tapping 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, REMS Picus S3 and REMS Picus SR
(fi g. 4)
WARNING
Inhalation of the dusts produced by dry drilling is harmful to the health. Observe
the national regulations. It is recommended to use a dust extractor to remove
drilling dust from the core bore. This consists of the REMS suction rotor ((46)
accessory art. no. 180160) for dust extraction and safety vacuum cleaner/dust
extractor of dust class M suitable for commercial use, e.g. REMS Pull M (Art.
No. 185501). Observe the operating instructions of the safety vacuum cleaner/
dust extractor. The suction rotor (46) is screwed to the drive spindle (11) of the
drive unit using the G ½ connector. The combined annular core bit connector
(47) on the opposite side permits the fi tting of diamond core drilling crowns with
female thread UNC 1¼ and the attachment of the tapping tool (49).
NOTICE
Always wet drilling for steel-reinforced concrete!
If the dust produced by dry boring is not removed, the diamond core drilling
crown may overheat and suffer damage. There is also a risk of injury when the
drilling dust compressed in the gap blocks the diamond core drilling crown.
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), remove the cover (14) and
attach the water supply system with the fi llister head screw supplied. The
quick-action coupling with water shutoff device should be fi tted with a ½" water
hose. Water pressure should not exceed 4 bar.
If there is no direct water connection available, water throughfl ow can be
achieved using the water pressure tank ((51) accessory art. no. 182006). Be
aware that there is suffi cient water fl ow.
When drilling with REMS Titan or REMS Simplex 2 the water extractor ((44)
accessory art. no. 183606) can be used. See Fig. 10 and 11 for assembly. This
consists of a water collecting ring, a pressure ring and a rubber washer (45).
The water extractor is fi xed to the base of the drilling column (1). The water
collecting ring is connected to a wet vacuum cleaner suitable for commercial
use, e.g. REMS Pull L or REMS Pull M. The rubber washer (45) must be cut
out exactly to fi t the diameter of the diamond core drilling crown.
2.6 Boring with a drill upright
Good results can be obtained by operating with a drill upright. The purpose 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 powerful infeed of the
diamond core drilling crown. REMS Picus S1, REMS Picus S3 and REMS Picus
SR can be mounted optionally on the REMS Simplex 2 or REMS Titan drill
stands. REMS Picus S2/3,5 must be mounted on REMS Titan.
In REMS Titan the clamping angle (10) or the REMS Picus S2/3.5 must be
mounted. The clamping angle (10) or the REMS Picus S2/3.5 must be inserted
in the guide (53) and fastened with the screws (52) for this.
The boring trestle (1) of REMS Titan is infi nitely adjustable up to 45°. This allows
angled core drilling operations to be carried out within this angle range. The
degree marks on the struts (40) serve for orientation. To adjust the angle, the
two screws (31) at the foot of the boring trestle (1) are removed. The hexagon
head screw (37) and all the screws on the two struts must be loosened. The
boring trestle can now be swivelled to the desired position. Retighten all screws
before proceeding. The screws (31) are not installed to produce the angled
core drilling operation(s). The swivel adjustment of the boring trestle causes
the useful stroke range of the feed device of the REMS Titan to decrease more
or less. This means that you may have to use corresponding annular bit exten-
sions ((50) accessory art. no. 180155) (see 3.7).
The feed slide (2) can be locked on the drill stands. Tighten the wing nut (32)
for this. Locking prevents such undesired movements as the accidental lowering
of the drive unit while the diamond core drilling crown is being replaced.
On all drill stands the feed lever (4) can be fi tted to the right or left of the feed
slider (2) according to local conditions (not preassembled in the as-delivered
state of REMS Simplex 2). Lock the feed slider as described above for this.
Unscrew the fi llister head screw (34). Pull the feed lever off the feed shaft and
push it onto the shaft stump opposite. Screw in and tighten the fi llister head
screw (34).
To achieve better stability when drilling with REMS Titan and REMS Picus SR,
the spacer set (38) can be mounted. For this, the clamping angle (10) may
have to be disassembled from the REMS Titan by loosening the screws (52).
Then clamping angle (10) is pushed onto the drill collar (13) of the REMS Picus
SR so that the tapped holes (60) of the gearbox casing of Picus SR are posi-
tioned in relation to the screw holes of the clamping angle (10). Insert the spacer
(without fi llister head screws) and align. Screw in the fi llister head screws
included in the set and tighten. Tighten the fi llister head screws (8) of the
clamping angle (10). Fix the mounted clamping bracket together with Picus SR
to the REMS Titan as described in 3.4.
