Diamond blades

WARNING: Never use a diamond blade to
cut plastic material. The heat produced
during cutting may melt the plastic and it can
stick to the cutting blade and cause a
kickback.
WARNING: Diamond blades become very
hot when used. An overheated blade is a
result of improper use, and may cause
deformation of the blade, resulting in
damage and injuries.
WARNING: Cutting metal generates sparks
that may cause fire. Do not use the product
near ignitable substances or gases.
Note: Diamond blades are available in several hardness
classes.
Note: Sharpen the blade by cutting soft material such as
sandstone or block.
• Always use a sharp diamond blade.
• Diamond blades can become dull when the wrong
feeding pressure is used or when cutting certain
materials such as heavily reinforced concrete.
Working with a dull diamond blade causes
overheating, which can result in the diamond
segments coming loose.
• Diamond blades consist of a steel core provided with
segments that contain industrial diamonds.
• Diamond blades are ideal for masonry, reinforced
concrete and other composite materials.
• Diamond blades ensure lower costs per cutting
operation, fewer blade changes and a constant
cutting depth.
• Special blades should be used when cutting metal.
Ask your dealer for help in choosing the right
product.
• When using diamond blade make sure that it rotates
in the direction indicated by the arrow on the blade.

Diamond blades for dry cutting
• Diamond blades for dry cutting can be used both
with and without water cooling.
• When dry cutting, lift the blade out from the cut every
30–60 seconds and let it rotate in the air for 10
seconds to let it cool. If this is not done, the blade
will become overheated.
Diamond blades for wet cutting
Note: Do not use Vac attachment when wet cutting. Wet
concrete sludge considerably reduces the suction
capacity of the Vac attachment.
• Diamond blades for wet cutting must be water
cooled. If this is not done, the blade may be
overheated.
• Water cools the blade and increases its service life
while also reducing the formation of dust.
• Water cooling, which is used when cutting concrete,
cools the blade and increases its service life while
also reducing the formation of dust. Disadvantages
include difficulties at very low temperatures, the risk
of damaging floors and other structural elements,
and the risk of slipping.
Diamond blade - side clearance
WARNING: Check that the diamond
segment (T1) is wider than the blade core
(T2) to prevent binding in the cutting slot and
a kickback.
Replace the blade before it is completely
worn out.
CAUTION: Certain cutting situations or poor
blades may cause excessive wear on the
side of the segments.
