4.2.1. Selection of the Cutting Disc
For safe and efficient operation, right selection
of the cutting disc is highly important. Choose a
high-quality
diamond
cutting
disc
and
appropriate type depending on the material to be
cut (asphalt, concrete).
Cutting discs of most suppliers are divided in
quality
categories
(standard/profi
etc.),
sometimes also according to length and height
of the diamond segments, spacing, etc.
Cutting disc diameter is to be selected according
to the type of the machine; if possible, choose
always the maximal allowed diameter (see point
2.1). The spindle speed is adjusted for this size
to keep optimal circumferential cutting speed of
the
disc.
