For wet applications.
Economic benefit is improved and
premature wear can be avoided by
choosing and using the correct diamond
cutting wheel. The short name (see
following explanation)
– on the label and
– on the packaging (table with
recommended uses)
can help to ensure the correct choice.
STIHL diamond cutting wheels are
suitable, depending on the version, for
cutting the following materials:
– Asphalt
– Concrete
– Stone (hard rock)
– Abrasive concrete
– Green concrete
– Clay bricks
– Clay pipes
– Ductile iron
– Structural steel up to 10 mm thick
Do not cut any other materials. Cut-off
machines are not suitable for cutting
certain metals and other substances.
Never use diamond abrasive wheels
with abrasive material on their sides,
since in a pinch situation, they can result
in extreme kickback – Risk of severe or
fatal injury.
Short names
The short name is a combination of
letters and numerals with up to four
digits:
– The letters indicate the main area of
use for the cutting wheel.
– The numerals indicate the
performance class of the STIHL
diamond cutting wheel.
Radial and axial run-out
A correctly mounted spindle bearing on
the cut-off machine is essential for a
long service life and efficient operation
of the diamond cutting wheel.
Using a cutting wheel on a cut-off
machine with defective spindle bearing
can lead to axial and radial run-out.
Excessive radial run-out (A) causes
individual diamond segments to be
overloaded and to overheat. This can in
turn lead to stress cracking in the wheel
core or to softening of individual
segments.
Axial run-out or spindle wobble (B)
results in higher thermal stress and
wider cuts.
