3.7) BROACH CUTTERS
These cutters rapidly produce high quality, accurate holes
in a single pass.The automatic lubrocooling system reduc-
es friction and eliminates heat build up during the drilling
operation. Under standard conditions a broach cutter can
drill 40-50 holes, depending on the hardness of the rail.

The type SR5000 coolant unit consists of a tank complete with tube and maximum pressure
valve (01), fitted with a pump device for pressurisation, which must be connected to the attach-
ment (35) on the drill by means of its quick-coupling (03).
The delivery and shut-off of the lubrocoolant are controlled automatically, when drilling
with a broach cutter, by the guide bit; when drilling with a spiral bit, delivery and
shut-off of the fluid must be effected manually by operating the tap (02). The use of
the lubrocoolant supplied by CEMBRE, in the recommended concentrations, guarantees
optimum use of the drilling tools.
Consumption of the lubrocoolant depends both on the variable degree of opening
of the tap (02) and the inner pressure of the tank: it is therefore advisable to open
the tap a little when the tank is at maximum pressure, while it must be fully opened
when the pressure in the tank is low.
When using the coolant system, pay careful attention to the instructions on the tank label.
Warning:
When the tank is not under pressure, check that the bush on the maximum pressure valve is
screwed right down.
To fill tank with lubrocoolant, turn handle anticlockwise approximately 2 turns to release
handle locking mechanism. Remove handle/piston assembly from tank.

ARE adaptor
FIG. 5 – ARE ADAPTOR
FIG. 4
The drill is equipped with a coolant attachment valve (35) and a vent valve (17)
which are located as shown (Fig. 3).
If under certain operating circumstances they need to be interchanged, proceed
as follows:
– Using a 17 mm hexagonal spanner unscrew the vent valve from its seat.
– Using the 4 mm allen key provided with the drill, remove the appropriate coolant valve
from its seat and fit into the vent valve seat.
– Fit the vent valve into the into the vacant coolant valve seat.
When temperatures fall below 32° F (0° C)
the lubrocoolant may freeze which could
cause damage to the seals contained in
the drill coolant system.
It is therefore advisable, when storing
the drilling machine, to empty the
lubrocoolant system completely.
Proceed as follows (Fig. 4):
– Disconnect the quick coupling (03)
from the coolant attachment (35) on
the drilling machine.
– Tilt the machine so that the coolant
attachment is at its lowest point - allowing
for natural drainage.
– Operate the advancing lever (36) to advance
and retract the drilling spindle.
– Gently shake the machine to expel all fluid.
4.1) ARE adaptor
For use with type SR5000 coolant unit. The ARE adaptor is inserted in the quick-coupling of the
tank tube (ref. to Fig. 5), it may be used to provide manual external cooling when cutters are
used to enlarge existing holes, or when using spiral bits not designed for automatic cooling.
If necessary the ARE adaptor can also be used to clean various parts of the drill, by means of the
lubrocoolant pressure jet, e.g. parts such as the tool clamping seat in the spindle shaft, seats
for the fixing screws, etc.

5. SPINDLE ADVANCE LEVER (Ref. to Fig. 6)
FIG. 6
The spindle is advanced by moving the lever
(36) (See Fig. 6 a). The lever is fitted with a re-
lease pawl (39) which, when pressed, renders it
independent of the hub and hence the spindle;
the operator can therefore easily vary the an-
gular position of the lever without movement
of the spindle (Fig.6).
FIG. 7
5.1) Adjustment of the advance lever
The movement of the lever must never be
loose, for adjustment proceed to tighten it
by loading the cup springs by means of the
associated self-locking nut, after removing
the protective cap (see Fig. 7).
6b - With the release pawl (39) pressed, the lever is
released from its hub and can repeat the previ-
ous travel without the spindle moving.
6c - With the hub released, moving the lever
towards the operator causes a corre-
sponding advance of the spindle.
6a - Moving the lever (36) towards the operator;
corresponding advance of the spindle.

6.1) Assembling broach cutters (Ref. to Figs. 8-11).
6.1.1) Insert the pilot bit in the cutter from the side of the spigot.
6.1.2) Using the lever (36), position the spindle shaft (07) so that both grub screws (18)
become accessible and sufficient space is provided to insert the cutter; if necessary
rotate the spindle shaft manually and sufficiently by inserting the 4 mm male hexagon
key in the appropriate intermediate gear housing (33) in the crankcase of the drill
(see Fig. 11).
6.1.3) Insert the cutter in the spindle shaft so that the two engaging dogs on the cutter
spigot line up with the grub screws (18).
6.1.4) Clamp the cutter by fully tightening the grub screws by means of the 4 mm allen key.
6.1.5) Check that the guide bit slides freely by applying slight pressure on it.
FIG. 8 – ASSEMBLING BROACH CUTTERS
6.2) Assembling special spiral bits (Ref. to Figs. 9 - 11)
6.2.1) Using the advance lever, position the spindle shaft so that both grub screws become
accessible and sufficient space is provided to insert the spiral bit; if necessary rotate
the spindle shaft manually and sufficiently by inserting the 4 mm male hexagon key
in the appropriate intermediate gear housing (33) in the crank-case of the drill cor-
responding to the feed handle (see Fig. 11).

6.2.2) Insert into the spindle shaft, the DPE spacer required to activate the coolant system.
If it necessary to use an APE... adaptor, the bit must first be fitted into the corre-
sponding APE adaptor and locked with the appropriate grub screw, then the DPE
spacer inserted.
Note: Adaptors type APED… (e.g. APED 3/8Y) do not require use of DPE spacer.
6.2.3) Insert the bit-spacer unit in the spindle shaft so that the two engaging dogs on the
bit spigot line up with the grub screws. Press the bit-spacer unit home against
the inner seat of the spindle: this will enable the DPE spacer to open the
coolant circuit (see Fig. 10).
6.2.4) Clamp the bit by fully tightening the two grub screws (18) using the 4 mm male allen
key.

The special shape of the positioning shoes, each corresponding to the type of rail, enables
the drill to be positioned quickly, accurately and safely on the element to be drilled.
To position the drill, complete with the clamping termination (§ 7.1) and the positioning
template (§ 7.3) suitable for the type of rail to be drilled, proceed as follows:
7.4.1) Withdraw the spindle shaft (07) completely by means of the lever (36).
7.4.2) Bring the moving arm (03) of the clamping device into the fully open position by
means of the handwheel (11).
7.4.3) Place the drill on the rail at the point where the drilling is to be carried out, and
clamp it by tightening the handwheel (11) right down: the positioning shoe will
automatically position the cutter or spiral bit in line with the desired axis; if accurate
positioning relative to the longitudinal axis of the rail is required, use the reference
pin (18).

FIG. 17 – DRILLING
N.B.: switch on the cooling system before starting the drill (§ 4)
8.1) Drill fitted with “short” type broach cutter (depth of cut 7/8").
The drilling sequence may be started with the drill fitted with the broach cutter (§ 6.1),
positioning jig (§ 7.2), the drill being clamped to the rail (§ 7.3), as follows:
8.1.1) Connect the female quick-coupling of the SR5000 cooling system to male coupling
(35) on the drill.
8.1.2) Open the tap (02) fitted on the tank tube.
8.1.3) Using the lever (36) bring the guide bit almost in contact with the rail (Fig. 17a);
keeping the release pawl (39) pressed, release the lever from its cup and return it
to the initial position (Fig. 17b), which will enable the travel of the lever (36) to be
used in the most advantageous way.
