Our cutting blades are manufactured for high-speed, portable 
power cutters. If blades from other manufacturers are used, 
ensure that the blades conform to all regulations and 
demands that concern this type of power cutter.

Some cutting blades are designed for stationary equipment 
and for use with attachments.Such cutting blades must not be 
used on portable power cutters.

Always contact local authorities and make sure you are 
following applicable directives.

The cutting material on abrasive discs consists of grit bonded 
using an organic binder. ”Reinforced blades” are made up of 
a fabric or fibre base that prevents total breakage at maximum 
working speed if the blade should be cracked or damaged.

A cutting blade’s performance is determined by the type and 
size of abrasive corn, and the type and hardness of the 
bonding agent.

Check that the blade is approved for the same or  higher 
speed according to the aproval plate of the engine. Never use 
a cutting blade with a lower speed rating than that of the 
power cutter.

Ensure the blade it not cracked or damaged in any other way.

Test the abrasive disc by hanging it on your finger and tapping 
it lightly with a screwdriver or the like. If the disc does not 
produce a resonant, ringing sound it is damaged.

Diamond blades consist of a steel body provided with 
segments that contain industrial diamonds.

Diamond blades ensure lower costs per cutting operation, 
fewer blade changes and a constant cutting depth.

When using diamond blades make sure that it rotates in the 
direction indicated by the arrow on the blade.

Always use a sharp diamond blade. Sharpen the blade by 
cutting in a soft material such as sandstone or brick.

Diamond blades are available in several hardness classes. A 
"soft" diamond blade has a relatively short service life and 
large cutting capacity. It is used for hard materials such as 
granite and hard concrete. A "hard" diamond blade has a 
longer service life and reduced cutting capacity, and should 
be used for soft materials such as brick and asphalt.

Diamond blades are ideal for masonry, reinforced concrete 
and other composite materials. Diamond blades are not 
recommended for cutting metal.

Diamond blades for wet cutting should have water poured 
over them during the cutting to cool the blade and bond the 
dust.

Diamond blades for dry cutting are a new generation of 
blades that do not require water cooling. However, the blades 
will still be damaged by excessive heat. It is most economical 
to allow the blade to cool by simply lifting it out from the cut 
every 30–60 seconds and letting it rotate in the air for 10 
seconds.

Concrete

Concrete, asphalt, 
stone masonry, cast 
iron, aluminium, 
copper, brass, cables, 
rubber, plastic, etc.

Can be used to reduce 
dust. Run the disc dry 
for about a half minute 
after using an abrasive 
disc with water 
cooling.

Metal

Steel, steel alloys and 
other hard metals.

NOT recommended
