8 Diamond Abrasive Wheels
– on the packaging (table with recommendations
for use) is an aid to selection
STIHL diamond abrasive wheels are suitable,
depending on the version, for cutting the follo‐
wing materials:
– Asphalt
– Concrete
– Stone (hard stone)
– Abrasive concrete
– Fresh concrete
– Clay brick
– Clay pipe
Do not cut any other materials – Risk of accident!
Never use diamond abrasive wheels with side
plating as they jam in the cut and can result in
extreme kickback – Risk of accident!

8.2
A faultless spindle bearing of the cut-off machine
is necessary for a long service life and efficient
functioning of the diamond abrasive wheel.
Using the abrasive wheel on a cut-off machine
with a faulty spindle bearing can lead to devia‐
tions in radial and axial run-out.
An excessively high radial run-out deviation (A)
overloads individual diamond segments, which
overheat in the process. This can lead to stress
cracks in the parent wheel or to annealing of indi‐
vidual segments.
Deviations in axial run-out (B) result in higher
thermal loading and wider cuts.
