This is how a diamond blade works
How does a diamond blade work?
A diamond blade does not cut but works
by milling. During the sharpening process Diamond crystal
performed at the factory, individual diamond Metal matrix
crystals are exposed on the face and sides
of the segment and it is these that do the Blade's direction of rotation
milling work. The metal matrix holds each
diamond in place. During the work, each Exposed diamond
diamond is supported by a comet’s tail
which strengthens the supporting action of “Comet tail”
the bond immediately “behind” the diamond Material to be cut
crystals.
The diamonds exposed in this way cut into the material reducing it to fine powder.
During cutting, the exposed diamonds may crack or break (all the more rapidly, the harder
and denser the material)
Simultaneously, the material starts to wear out the metal matrix in the segments by abrasion,
which allows the gradual release of new diamonds.
The Price
Determine what is most important to you: the purchase price of the tool or the cost per cut. For less important jobs or for occasional use, a cheaper
tool may be the right choice. For more important jobs or for regular use, a more
expensive tool with a low cost per cut (per square meter) is preferable as it provides better results and performance.
Material to be cut
The correct identification of the material you are going to cut is the most important factor when choosing a tool. The material has a direct influence on
the cutting speed and the service life of the tool. Throughout the catalog you will find tables explaining the various applications of the diamond tools;
these should help you choose the most
appropriate tool for your work.
Dry or wet cutting?
This choice may depend on the user’s preference or on some particular constraint associated with the work to be done. For concrete saws, wet
cutting is preferable as it allows deeper cuts and prolongs the service life of the blade. For tile and masonry saws, dry- or wet-cutting tools may be
used equally well. For general purpose site saws,
dry-cutting tools are most frequently used. Wet cutting is used primarily to limit the amount of dust. If you experience problems with wobbling when
using a high-power handheld machine cutting dry, try wet cutting. This will cool down the blade and solve the problem. Some diamond blades and
drill bits, must be used together with water. Dry-cutting tools may be used with or without water, depending on the machine and the material to be
cut.
