Are you involved in concrete cutting? Do you know the difference between wet concrete cutting and dry concrete cutting? Please continue reading below to learn more.
Diamond cutting blades are some of the most effective concrete cutting blades available today. Concrete sawing and grinding have become easier and more effective today with the introduction of diamond blades.
This article provides information on diamond blades and wet vs. dry concrete cutting. In the process, we will take a look at the following:
- Diamond Concrete Blades
- Wet Concrete Cutting
- Dry Concrete Cutting
Diamond Concrete Blades
These blades are made of diamonds that are arranged in a metal matrix. Diamond blades consist of two major components such as the steel core and the segment.
The steel core is a round and flat metal disc that supports the outer segments of the blade. Diamonds are attached to the metal core using laser welding, sintering or vacuum brazing methods.
Diamond blades grind the concrete surface more than cutting it. The diamond crystals in the blade will do the grinding work and the metal matrix will hold the diamonds in place.
There is a “bond tail” that trails behind each exposed diamond in the blade – which helps support the blade. After extensive use, the exposed diamonds will begin to crack and fracture.
The matrix that holds the diamonds will also wear off. Eventually, the diamonds will completely break up. The cycle of erosion will continue until all of the diamonds in the metal are gone.
This is the time the operator needs to replace the blade of the cutting device.
Wet Concrete Cutting
Wet cutting is a popular method for cutting concrete surfaces. The latest studies show that wet cutting is ideal for controlling dust exposure. Silica dust can be harmful to your health and well-being in the long run.
It affects the lungs and respiratory system and can result in lung cancer and even death with regular exposure. Water is used in wet concrete cutting applications to wash out particles and remove silica dust.
Water will also act as a coolant for the cutting blade and help make deeper cuts in the concrete surface. Water will also prolong the lifespan of the diamond blade. That’s why wet concrete cutting is encouraged most of the time.
If you want to keep silica dust away when cutting concrete, you should opt for a wet cutting device. Using water will reduce the respirable dust concentration by at least 85%.
Water also prevents the diamond blades from overheating when cutting concrete. Overheating can reduce the lifespan of the blade and make it inefficient after some time.
Water lubricates the blade and improves its efficiency in the process. Wetting will also make the cutting process less noisy. Wet cutting will keep everyone safe if you choose to cut concrete in your home or garden.
Dry Concrete Cutting
Dry cutting is another popular method of concrete cutting. You should select the right diamond blade for dry cutting. A laser-welded diamond cutting blade is the best option in this regard.
These blades are specifically designed for dry cutting. Alternating and thin cutting is encouraged in dry cutting to let the air flow around the blades. Air is needed to cool the blades in the process of dry cutting.
That’s why dry cut blades are made with wide space between segments. The operator doesn’t have to apply great force when using a dry-cutting blade. Great force can damage the blade due to overheating.
