workpiece will not become too hot, does not discolour and
no grooves are formed.
Flap disc
With the flap disc (accessory), curved surfaces and profiles
can be worked. Flap discs have a considerably higher service
life, lower noise levels and lower sanding temperatures
than conventional sanding sheets.
Cutting metal
► For cutting metal, always work with the protection
guard for cutting 7.
When cutting, work with moderate feed, adapted to the
material being cut. Do not exert pressure onto the cutting
disc, tilt or oscillate the machine.
Do not reduce the speed of running down cutting discs by
applying sideward pressure.
Cutting stone
► For cutting stone, always work with the cutting guide
with dust extraction protection guard 19.
► The machine may be used only for dry cutting/grinding.
For cutting stone, it is best to use a diamond cutting disc.
As a safety measure against jamming, the cutting guide with
dust extraction protection guard 19 must be used. Operate the
machine only with dust extraction and additionally wear a dust
protection mask. The vacuum cleaner must be approved for
the extraction of masonry dust. Bosch provides suitable
vacuum cleaners.

process and allow the diamond cutting disc to cool by running
the machine for a short time at maximum speed with no load.

are indications of a diamond cutting disc that has become
dull. Briefly cutting into abrasive material (e. g. lime-sand
brick) can resharpen the disc again.
