Diamond blades for wet cutting
• Diamond blades for wet cutting must be used with
water.
• Water decreases the temperature of the cutting
blade, increases its service life and decreases dust
during operation.
• When wet cutting, collect the waste water safely.
Diamond blades for dry cutting
• For diamond blades for dry cutting it is necessary to
have a sufficient airflow around the cutting blade to
decrease the temperature. Because of this, diamond
blades for dry cutting are recommended only for
intermittent operation. After some seconds of
operation, it is necessary to let the diamond blade
rotate freely, away from the cut. This lets the airflow
around the blade decrease the temperature of the
diamond blade.
Diamond blade - side clearance
WARNING:
poor blades can suffer excessive wear on
the side of the segments. Make sure the
diamond segment (A) is wider than the
blade (B). This is to prevent pinching in the
cutting slot and kickback. Refer to
on page 18 .

the spindle shaft.
To do a check of the arbor bushing
The arbor bushings are used to attach the product to the
center hole of the cutting blade. The product is supplied
with one of these two types of arbor bushings:
• An arbor bushing that can be turned to the other side
and be applicable for 20 mm/0.79 in. or 25.4 mm/1
