Concrete Cutting – Diamond Saw Blades Overview
There are a lot of different technologies in the field of concrete cutting. Diamond saw blades are often the best choice when it comes to making clean, professional cuts in concrete. With so many different options in terms of type and price; Do you know how to choose the perfect one and what are the benefits of diamond cutting concrete?
It is important to understand how diamond blades work in terms of choosing a blade with the proper quality of cut. These are made with synthetic crystals that cut through absolutely anything. As the blade rotates at high speed, the exposed crystals cut through the material. With continued use, the surface diamonds are wasted and the matrix begins to expose new diamond crystals.
To ensure its maximum life, you should match the blade as closely as possible to the material being cut. A diamond blade used to cut soft and abrasive materials (such as green concrete) must have a carbide bond to ensure that the exposed diamonds are fully utilized. In contrast, a blade for cutting hard concrete must have a smooth bond that allows the exposure of new diamonds.
Cutting concrete at the right time is important. If you are placing new concrete, you have two options: cut the concrete while it is still green or the next day when it is hardened. This will affect the type you need.
The decision to cut wet or dry depends on your job requirements and preferences. Dry cutting eliminates the need for hoses and water tanks, while using a wet blade reduces dust. The main difference between dry and wet sheets is the welds. It is important to emphasize that dry cutting blades can be used in wet conditions, but you should never use wet cutting blades without water. Always cool the blade with water to avoid deformity.
Match the blade to the speed range of the saw. Running the blade at a lower speed than recommended may reduce its cutting performance. Operating the blade at a higher speed can also damage the blade. You should always maintain blade compatibility.
Manufacturers offer diamond blades at various levels of quality and cost. You can choose from shovels from entry-level economy to professional. The key difference is the diamond content, the higher raw material cost in making these blades. At this point you must decide which is more important to you: the initial cost of the blade or the total cost of sawing. Buying an inexpensive blade is suitable if you are doing small cutting jobs or if you don’t use the blade very often. For frequent use or large jobs, you should buy a better quality blade. It will cost you less in the long run.
