Diamond blades

General
WARNING! Cutting plastics with a
!
diamond blade can cause kickback when
the material melts due to the heat
produced when cutting and sticks to the
blade.
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.
Cutting metal generates sparks that may
cause fire. Do not use the machine near
ignitable substances or gases.
• Diamond blades consist of a steel core provided with
segments that contain industrial diamonds.
• Diamond blades ensure lower costs per cutting
operation, fewer blade changes and a constant cutting
depth.
CUTTING BLADES
• When using diamond blades make sure that it rotates
in the direction indicated by the arrow on the blade.
Diamond blades for different materials
• Diamond blades are ideal for masonry, reinforced
concrete and other composite materials.
• Diamond blades are available in several hardness
classes.
• Special blades should be used when cutting metal.
Ask your dealer for help in choosing the right product.
Sharpening diamond blades
• 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.
• Sharpen the blade by cutting in a soft material such as
sandstone or brick.
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 may
be overheated.
Diamond blades for wet cutting
• 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.
