An angle grinder is a common electric tool widely used for working and cutting metal, stone and other materials. When using an angle grinder, sometimes dangerous situations occur, such as saw blade falling and flying out, which requires us to understand safe use of angle grinder and how to prevent saw blade from falling and flying out.
First, we need to understand how an angle grinder works. An angle grinder cuts objects with a cutting disc that rotates at high speed. There are generally two types of cutting discs: abrasive cutting discs and cutting blades. Among them, cutting wheel of grinding wheel is suitable for hard materials such as metal and concrete, while cutting wheel is suitable for soft materials such as plastic and stone. When using an angle grinder, a suitable cutting disc must be selected.
Secondly, there are many reasons why a saw blade falls off and flies out. This may be caused by quality of cut-off wheel, long-term use or impact. In addition, using wrong cut-off blade when working with an angle grinder can also cause saw blade to come off. In addition, improper operation during use may also cause saw blade to fall, such as wrong angle, shaking too hard, etc.
So, how to prevent saw blade from falling and flying out?
First of all, we need to choose reliable quality cutting discs, try not to use poor quality cutting discs, so as to avoid danger of quality problems. Second, check wear of cutting disc before use. If cutting disc is found to be worn or has been used for a long time, it should be replaced in time. In addition, pay attention to safety when using angle grinders, choose correct working angle and direction, and try to avoid shaking so as not to create additional pressure and shock on cutting disc.
Summarizing, you can avoid falling and flying out of saw blade. You only need to select appropriate cut-off wheel, pay attention to safe operation, and replace worn-out cut-off wheel in time to ensure safety of angle grinder.
