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 order to choose a blade with the proper cut quality. These are made with synthetic crystals that will cut through absolutely anything. As the blade rotates at high speed, the exposed crystals cut into the material. With continued use, diamonds on the surface are wasted and the matrix begins to expose new diamond crystals.
To ensure its maximum life, you must match the blade as close as possible to the material being cut. A diamond blade used to cut soft, 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 should have a smooth joint that allows for the exposure of new diamonds.
It is important to cut the concrete at the right time. 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 hard. 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 wet and dry blades 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 deformation.
Match the blade to the speed range of the saw. Operating the blade at less than the recommended speed 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 between rackets from the basic economic level to the professional. The key difference is the diamond content, the higher raw material cost in making these blades. At this point you must decide what is more important to you: the initial cost of the blade or the total cost of the sawing. Buying an inexpensive blade is fine if you do small cutting jobs or 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.
