How to Choose Proper Diamond Blades to Saw Concrete If you fail to choose right diamond blades to cut the concrete, the diamond blades may have short life, cut slowly or even do not cut, and some other issues may also occur. So it will be very helpful for you to learn some methods to choose proper diamond blades. You can consider the following aspects:
The concrete's type A diamond blade usually consists of a steel core and many diamond segments on its edge. Diamond segments, the cutting teeth, are the effective part of the blade. Diamond blades used to saw concrete can be called diamond concrete saw blades, which are specially made to cut concrete. As concrete has many types, for example, reinforced concrete or concrete without steel bars, green concrete or cured concrete, and the aggregates and sand may also be different, there are many types of diamond concrete saw blades to fit these different concretes. The gullets of diamond concrete saw blades are often keyhole‐shaped. The main differences exist in their diamond segments, which consist of diamonds and bond materials. Depending on the properties of the concrete(e.g., the diameter of the steel bar in reinforced concrete, the size of the aggregate stone in concrete road), the diamond segments' formula, which means what diamonds and bond materials should be used and their percentages, should be designed to fit the concrete's properties. So when buying a diamond concrete saw blade, you should consider what concrete you will cut and then determine the corresponding saw blade.
Whether you need wet cutting or dry cutting Concrete is usually cut with water. This can reduce the dust, improve cutting efficiency, and extend the diamond blade's life. However, in some cases, for example, there is no water source near the work area, you have to perform dry cutting. As using the air as the coolant, dry cutting should be shallow and intermittent. In addition, the diamond blade should be laser welded and specially designed for dry cutting, and should be made sharper. Silver brazed diamond blades should not be used in dry cutting, for the high temperature generated in the dry cutting process may melt the silver solder, and the diamond segments may fly out and may hurt the operator or the people nearby.
Your concrete saw machine Your concrete saw machine may accommodate some certain diameters of diamond saw blades. So you should make sure that the diameter of the blade you are buying can match. Also you should note the arbor hole size of the blade. It should fit the arbor of your saw machine. Another important thing which should be considered is the horsepower of your concrete saw machine. As during the cutting process big‐powered machines exert bigger force on the

Otherwise the diamond blades may be consumed faster and have a shorter service life.
What performance feature you prefer Same quality grade diamond blades can have different performance features, e.g., faster cutting speed or longer service life. Normally, in the same quality grade, faster cutting speed leads to shorter service life, and vice versa. So you can balance the cutting speed and the service life when buying the diamond saw blades.
