It is suitable for drilling into rock, concrete, asphalt and masonry. Through the addition of water through
the diamond drill bit (3) via the ball valve (1a) the drilled material is flushed away and the tool is cooled
(wet drilling). The drilling tool, the diamond drill bit (3), is a tube drill which is fitted with soldered-on or
welded-on segments impregnated with diamond splinters.
If necessary, the flushing water is extracted through a water collecting ring (4) by means of a suction unit.
The machine may not be used for a different purpose or with a different tool.
The SR25/38/65/68/75 is water protected and therefore corresponds to the water protection class IP 55.
The motor is water-cooled, i.e. the cooling and rinsing water flows through the cooling coil of the motor
before being leaded to the drill bit.
On proper use water can not enter the machine. Thus it is possible to drill upwards vertically (overhead
drilling) without any further precautions.
In the SR25/38/65/68/75 an undervoltage trip is integrated, i.e. after a break of the mains voltage the
machine doesn't start accidentally on return of the voltage.
The SR25/38/65/68/75 is fitted with a novel SR-motor (SR = switched reluctance). The commutation
(alternating currenting of the stator poles) is managed by a power electronic which gets its orders from
a microcomputer. The speed is over the whole capacity range almost constant, therefore the start drilling
is made easier.
The SR38/68/75 are fitted with a 3-speed gear box. Besides the three gear speeds, the motor can
additionally be operated in different speeds. Thus the different speeds according to the table below can
be selected.
The speeds of the SR25/65 are only changed via the motor, thereby six motor speeds can be chosen,
which can also be changed while drilling.
