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

3.8) SPECIAL SPIRAL TWIST BITS
Using these bits guarantees optimum performance during the drilling operations. As a rule, under
normal conditions, a spiral bit can drill 70-100 holes, depending on the hardness of the rail.
For tools of other types, check the dimensional compatibility (particularly the size of the attachment and the length).

Detail of the
max pressure valve
FIG. 3 – COOLANT UNIT
The type SR5000 coolant unit (01) consists of a tank complete with tube and maximum pressure
valve, fitted with a pump device for pressurisation, which must be connected to the attachment
(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.

•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.
ARE adaptor
FIG. 5 – ARE ADAPTOR
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 jig fixing screws, etc.

The spindle is advanced by moving the lever
(36) (See Fig. 6 a). The lever is fitted with a
release pawl (39) which, when pressed, ren-
ders it independent of the hub and hence
the spindle; the operator can therefore easily
vary the angular position of the lever without
movement of the spindle (Fig.6).
6c - With the hub released, moving the lever towards the
operator produces a corresponding advance of this
spindle.
6a - Moving the lever (36) towards the operator produces
a corresponding advance of the spindle.
5.1) Adjustment of the advance lever
Themovementofthe levermustneverbe 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).

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 corresponding to the feed handle
(71) (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 male hexagon
key.
6.1.5) Check that the guide bit slides freely by applying slight pressure on it.
6.2) Assembling spiral bits (Ref. to Figs. 9 - 11)
6.2.1) Using the advance lever, position the spindle shaft so that both grub screws become acces-
sible 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 in the crankcase of the drill corresponding 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 corresponding
APE adaptor and locked with the appropriate grub screw, then the DPE spacer inserted.
Note: Adaptors type APED… (e.g. APED 135/165) 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.

7.4) Clamping to the rail web (Ref. to Fig. 16)
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 shoe (§
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 rod (18).

Check engine oil level before operation (see § 13.2.4)
Switch on the cooling system before starting the drill (see § 4)
8.1) Drill fitted with “short” type broach cutter (for drilling thicknesses of up to 1").
The drilling sequence may be started with the drill fitted with the broach cutter (§ 6.1), clamping
termination (§ 7.1), positioning shoe (§ 7.3), the drill being clamped to the rail
(§ 7.4), as follows:
8.1.1) Connect the female quick-coupling of the SR5000 coolant unit to the male coupling (35)
on the drill.
8.1.2) Open the tap (02) fitted on the coolant unit hose.
8.1.3) Using the lever (36) bring the guide bit
almostincontactwith therail(Fig.17a);
keeping the release pawl (39) pressed,
releasetheleverfromitscupand return
intotheinitial position(Fig.17b),which
will enable the travel of the lever (36)
to be used in the most advantageous
way.
