Angle Grinder Safety

Angle grinders combine two dangerous elements together, a high RPM spinning motor with a sharp cutting disc. The following safety tips should always be considered to help avoid serious injury:

Ensure the device is switched off before you plug it in. Before plugging an angle grinder into the power source, make sure that the machine itself is switched off.

Read the manual and understand how it works. Even for an experienced user when getting a new power tool it is always a good idea to read the manual to ensure that you are completely familiar with the modes of operation and the features of the tool. Power tools are inherently dangerous machines, so this is very important.

Use the right grinding disc for the job. It is important that not only that you use the correct disc size for the angle grinder, but also that you use the right type of disc for the material. For example, using a metal cutting disc to cut ceramic and stone may at best wear the disc down too fast, but, at worse, may put you in danger by breaking the material.

Wear the right clothing and protective gear. It is always a good idea to protect yourself by wearing the appropriate safety gear when using an angle grinder. Not only can an angle grinder produce a lot of sparks, but it can also throw up cutting debris. For this reason, it is imperative to wear safety goggles. It is also a good idea to wear safety gloves. Depending on the circumstances and ventilation, it can be a good idea to wear a dust mask. This is beneficial when cutting masonry or ceramics, as in a closed environment these materials can generate a lot of dust. Using grinders in certain situations can also be quite noisy, so ear defenders may also be needed.

Use the grinder correctly. Some people remove the safety guard from the grinder, to make it easier to carry out certain jobs. This is a bad idea, the safety guard is there for a reason and should always be kept it in place. You should also always use an angle grinder with two hands, as they can twist out of your hands if you are not careful. Furthermore, you should inspect a power tool before you start a job and replace any parts before use if they are not in a good condition.

Keep your attention focused. Angle grinders are dangerous tools to use so it is important to keep focused and attentive to the job. Avoid distractions and take regular breaks.
