SELECT A DIAMOND TOOL
- The buyer is solely responsible for the correct selection of
correct use of the diamond tools. The claims are invalid in case
of incorrect selection or misuse or not observing to safety
instructions.
It is the fact that 99.9% of problems are caused
by operate error and not product failure. Our blades should not
fall if used correctly.
- What is a diamond saw
blade
A diamond saw blade is composed of the
circular steel core and the diamond-impregnated segment. The
segments separated by slots in the core. These slots assist in
cooling the blade during sawing by allowing water (wet cutting) or
air (dry cutting) to flow between the segments.
The segments or
rims are a mixture of diamond powders and metal powder. The
diamonds are Industrial diamonds of different sizes and qualities
depending on the material to be cut and blade type. During the
process the metal powder and diamond powders are compressed at
very high temperature and pressure to obtain the bond, which
retains the diamond grain.
- How to make a diamond
saw blade
Laser welding: laser micro-fusion enables
the segment to be welded to the core. The bond is the most
powerful; it enables the tool to be used for dry cutting and
drilling without segment loss.
Brazing: silver brazing solder
melts at high temperature between the segment and the core and
binds the two elements together. This used for wet cutting,
drilling and grinding.
Sintering: it divides into two Cold
pressed-Sintered: First pressed with press machine under normal
circumstances, and then laid in sinter machine under high pressure
and temperature making the compressed metal powder to a solid
bond.
Hot pressed: Pressed with hot machine under high
temperature and pressure, making the compressed metal powder to
melt to a solid bond.

- How does a diamond blade
work
The individual diamond crystals exposed on
the leading edge and the sides of the segment or rim carry out the
cutting (in fact it is milling).
The operator pushes the
rotating blade into the material. The surface diamonds thus
exposed mill a groove in the material, reducing it to fine powder
when the blade mills the material, the latter exerts wear on the
blade.
During cutting the exposed diamonds may crack or break.
The material simultaneously starts to abrade the metal matrix,
which gradually releases more diamonds. The more abrasive the
material, the more rapid the tendency to wear down the
matrix.
Blades for cutting hard, dense less abrasive materials
(such as tile, hard bricks, stone or cured concrete), require a
softer metal matrix. This will wear faster, replacing the worn
diamonds fairly quickly so that the blade continues to cut. Blades
for cutting soft, abrasive materials (such as green concrete and
asphalt) must have a hard, abrasion-resistant metal matrix in
order to retain the diamonds for a long time.

- How to selecting a diamond
tool
When choosing a diamond
tool you should follow under step by step.
Step 1: How to use-Cutting or Drilling or
Grinding
Be sure that cutting blade is deadly dangerous
to use for grinding and making a hole. You should not take the
risk just to save meaningless small money using one blade doing
all the work. Please refer to the detail content in the
brochure.
Step 2: What kind a machine to use
on
Step 3: Blade usage – How
often you will use it and how long a life and how fast a cutting
speed you required
- Professional Purpose: for large civil engineering construction
on a regular daily basis, require long life (less expensive per
cut/meter) and fast cutting speed.
- Builder’s (contractor) Purpose: for regular use with medium
life, fast cutting speed no need the same life of a professional
blade.
- DIY Purpose (trade): for small scale occasional use, require
fast cutting speed and reasonable life.
- Promotional Purpose: cut well with water but with short
life.

- Step 4: Blade Purpose – Consider
what materials you to be cut
Asphalt; Concrete; Brick; Block;
Stone; Tile or General Purpose (this type can cut many of the
materials, but can not get the best performance as special
professional ones).
- If you want a blade that will cut both granite and asphalt
well then you will need to buy two different blades. You cannot
expect the blade to work correctly and safely on both materials.
The blade will either become blunt and overheat or it will wear
very quickly.

- Step5: Blade Type: A continuous
smooth rim provides the smoothest cut in ceramic tiles and
ornamental stone. Turbo type blades or segments turbo type may
produce slight chipping but generally have a longer life and lower
cost per cut than continuous rim blades. Segmented blades provide
the longest life and lowest cost precut but are only suitable for
work where chipping is not a problem.

- Step 6: The Price: For small jobs,
or occasional use, a low-priced tool may be preferable. For larger
jobs or regular use, a higher-priced tool will actually be less
expensive to use because it will deliver a lower cost per cut. For
really big jobs, the lowest possible sawing cost (cost per meter)
is usually much more important than the initial price.
