Areas of application
The DSWS15 is an electrically-powered wire saw which,
by means of its diamond wires, is capable of sawing
through construction materials ranging from heavily
reinforced concrete to metre-thick masonry. Equipped
with the appropriate accessories, it can be used to cut
openings of all kinds and for the technical demolition of
construction components of any shape, thus present-
ing almost limitless application possibilities. Sawing
operations are normally carried out wet, using water
cooling, but masonry can also be sawn dry.
DS WS 15 basic system units
The basic equipment consists of the following compo-
nents: drive unit, control unit, compressor, 2 single-pair
pulley stands, 1 toolbox containing tools and acces-
sories, 2 water supply nozzles.

DS-WS-SPP single-pair pulley stand
The basic equipment includes 2 single-pair pulley
stands. These are adequate for most applications but
it is also possible to use more than 2 single-pair pul-
ley stands for applications where access is difficult
(in cellars, corners, shafts).
Toolbox containing accessories and tools
Long water supply nozzle
For use at the rear of the object being cut, deep in the
saw kerf.
쐆Flexible water supply nozzle
For use at the wire entry point on the return side (slack
side) located at the front of the object being cut.
