Most diamond cutting wheels are
suitable for wet cutting
Wet cut whenever feasible. It
increases the service life and cutting
speed of diamond cutting wheels.
Ensure that the cutting wheel is
generously supplied with water.
Wet cutting helps to suppress dust.
The water binds the dust.
The cutting wheel must be supplied with
at least 0.6 liters water per minute.
Wet cutting can reduce the energy of
reactive forces.
In a pinch situation, the
water can act as a lubricant.
Water connection
–
A water attachment kit is mounted
on the machine for use with all types
of water supply.
–
A pressurized 10 liter water tank is
available from STIHL for dust
suppression.
–
A water tank for mounting on the
Cutquik cart is also available for
dust suppression.
Composite resin wheels can be used
for dry cutting of metals or for wet or
dry cutting of concrete, stone or
masonry.
Composite resin wheels designed for
dry cutting
Special procedures must be followed
when wet cutting with a composite non-
diamond wheel designed for dry cutting.
See the section entitled "Wet Cutting
with Abrasive Wheels" in the safety
precautions of this manual. Wet cutting
is generally not suitable for cutting
metals.
Composite resin wheels designed for
wet cutting
If the water flow rate is too high, the
cutting wheel may skim on the water
surface in the cut and greatly reduce
cutting performance. To avoid this, do
not exceed a water flow rate of about
4 L/min.
Use water properly:
1.
Be certain water is applied to both
sides of wheel, since uneven
distribution can cause one sided
wear with possible wheel breakage.
2.
Make certain water does not flow on
wheel that is not running, since the
wheel will absorb water and that will
affect wheel balance.
3.
After finishing work, run the cutting
wheel at normal operating speed for
about 3 to 6 seconds
without
water
so that the remaining water is flung
off.

Respiratory protection
Sample applications
Adjust water flow rate
during cutting so it is suf-
ficient to bind all the dust
that occurs (at least
0.6 L/min).
Warning!
When wet cutting at the recommended
flow rate is not utilized, the operator and
any bystanders should always wear a
respirator approved by NIOSH/MSHA
for the material being cut. Even if wet
cutting, an operator who is actively cut-
ting for more than two hours a day
should wear at least a NIOSH-approved
disposable respirator.
