What material are you cutting?

The characteristics of a diamond saw blade match as closely as possible the material you are cutting, such as cutting stone, granite, marble, concrete, asphalt, etc.

● What is the difference between a wet blade and a dry blade?

Wet and dry blades have a variety of uses and behave differently depending on the surface they are cutting. Generally, wet diamond blades perform better because they provide deeper cuts and reduce the possibility of overheating due to friction on the cutting surface. Overheating of the blade can cause a variety of problems, including damage to the parts inside the diamond blade. When the user cuts with a wet blade, water is used to keep it cool during the cutting process. It also acts as a cleaning mechanism to keep debris and dust out. Dry blades, on the other hand, are used in the absence of water or any other liquid. Dry blades tend to last much shorter than wet blades and wear out more quickly because they are exposed to intense heat and friction. Usually, dry blades can be used as wet blades, but on the other hand, wet blades cannot be used as dry blades because they run the risk of damage.

● Choosing wet or dry cutting?

When using power tools such as electric hand saws, it is not safe to use water due to the power source. However, diamond saw blades for concrete are often used for wet cutting because the concrete to be cut is very hard or abrasive.

If a saw blade is used without sufficient water, the diamond blade itself may break or the steel core beneath the blade may wear and break, and the blade may then fly out and possibly injure the operator or someone nearby. If for some reason a dry cut must be made, a sharper diamond blade should be selected and the dry cut should be intermittent and shallow to keep the diamond blade cool.

● In some cases, dry cutting should or must be performed. These situations include. 

▷ For some power tools, water is not safe due to the power source. 

▷ The work area needs to be kept dry. 

▷ There is no water source near the work area. 

● Proper operation of the dry diamond saw blade 

After obtaining a diamond saw blade suitable for dry use, if the operator fails to operate it properly, the excessive heat generated during dry cutting may still damage the diamond saw blade and the operation is very dangerous. 

Unlike wet cutting, which uses water as the coolant, dry cutting uses air to cool the diamond blade. During dry cutting, the operator should make intermittent and shallow cuts to allow air to flow around the diamond saw blade. 

▷ Intermittent cutting: The operator should not make continuous dry cuts for a long time. Instead, after a period of dry cutting, he should relieve the pressure on the diamond blade and allow the blade to run freely and at full speed, allowing the air to remain cool. The duration of each dry cutting operation can be from a few minutes to a few seconds, depending on the hardness of the material being cut. The harder the material, the more frequently the diamond blade will be cooled. 

▷ Shallow cuts: The operator should also make shallow cuts to avoid overheating the diamond saw blade. When deep cuts are required, he can make several shallow cuts (step cuts) to achieve this. 

Do not force the wall saw blade into the material: The operator should let the diamond saw blade cut at its own speed. Forcing the blade may result in overheating and blade damage. 

● For more information:

If you experience oscillation problems when performing a dry cut with a high-powered handheld saw, try a wet cut. This will cool the diamond blade and solve the problem. Not all materials can be cut dry. Very hard materials, such as concrete with strong reinforcement, should still be cut with sufficient cooling water. For concrete saws, wet cutting is preferable because it allows for continuous and deeper cuts, reduces dust, and can extend the life of the diamond blade.
