APPENDIX “A”
Factors which influence the number of holes that can be made according to the tool
used:
– Hardness of the material to be drilled.
– Thickness to be drilled.
– Stability of the drill clamping and correct assembly of the drilling tool.
– Suitable lubrocooling (lubrication/cooling) to keep the temperature of the tool low so
as not to compromise the efficiency of the cutting edges, whilst at the same time
facilitating the removal of the swarf.
– Contact time of the cutting edges of the tool with the material to be drilled; bear in
mind that the faster the hole is made the greater the efficiency.
– Observance of these basic rules:
1) Commence drilling by exerting light pressure on the advancing lever,
progressively increasing and then relaxing it when the tool is in the exit phase.
2) Avoid pressure surges and advance according to the diameter of the drilling diameter,
to avoid scratching the material or damaging the cutting edges of the tool.
3) Remember that a tool with efficient cutting edges requires a lower pressure than one
with which a certain number of holes have already been made.
4) When holes are made close to raised lettering on the rails, commence drilling
with very light pressure until the lettering disappears, to avoid possible breakage
of the tool.
5) Bear in mind that when operating on very hard rails, as in the case of quality 1100
steel, it is advisable to increase the lubrocoolant flow rate.
3.1) Battery pack
Two different battery power packs are
available to feed the drill:
– type BP 24-10 (24 V - 10 Ah)
weight: 11 kg
– type BP 24-16 (24 V - 16 Ah)
weight: 17 kg

14.1) Regularly check for correct tightening (torque) of the fixing screws of the drilling tools
and positioning shoes.
14.2) Avoid pressure jolts on the advancing lever during drilling.
14.3) Always make sure that the drilling swarf is properly removed before starting to drill a
new hole.
14.4) Incomplete clamping of the drill on the rail to be drilled may lead to the breakage or
accelerated wear of the drilling tool and damage to the spindle shaft bearings.
14.5) If it is necessary to operate the drill without the cutter inserted, remove the locking grub
screws from the spindle shaft.
14.6)
Avoid leaving the SR 5000 tank under pressure and exposed to sunlight for long
periods of time.
14.7)
Should the clamping device be removed, make sure that by reassembling it, the
two locking screws are firmily fastened.
14.8) After use, always put protection cap (22) back onto connecting plug (21) of
the drill.
