Angle Grinder Safety Tips – Everyone Should Know

Did you know that an Angle grinder is one of the most dangerous power tools in a workshop? This guide will discuss how to use your angle grinder safely to achieve great results. We will also cover some of the potential hazards and how to avoid them. So, whether you are a beginner or an experienced user, read on for angle grinder safety tips.

Can an Angle Grinder be Dangerous?

An angle grinder can be a dangerous power tool. It is suited to a variety of different tasks as a sheer number of tasks that it can perform with its powerful motor makes it one of the most versatile tools in your workshop. This versatility comes with an increased risk factor.

What are the dangers?

The most significant danger is the risk of slipping. Grinders spin at very high speeds, and if your hand slips onto the spinning disc or flange, it can be extremely painful. The hot sparks generated by an angle grinder are also a hazard, as they can easily cause burns. Finally, metal particles may get flung out of the disc and hit you in the eye.

Angle grinder accidents can also cause severe injuries to your fingers, hands, and legs. In fact, almost one-third of all grinder-related injuries come from someone slipping on a wet or oily surface. Unfortunately, many people underestimate how dangerous a tool an Angle grinder is until they have a serious accident.

Angle Grinder Safety: Personal Protection Equipment (PPE)

There are several PPE that should be worn when using an angle grinder to help you avoid serious accidents. Here are some angle grinders safety materials and requirements which include:

  • Hearing protection: If you have been working for a while with the grinder, your ears will have been exposed to loud noises. Wearing hearing protection during any more work will ensure that your ears don’t continue to be affected by the noise.
  • Eye protection: Using an angle grinder can fling metal particles up into the air at high speeds and can cause eye or facial injuries. Always use safety glasses or goggles with side shields to protect your eyes from being struck by these projectiles. If possible, don’t wear anything else on your head in case something does ricochet into your face or eyes.
  • Gloves: This may seem like an obvious one because gloves are the most important safety feature you must have in your toolbox, but you should always wear gloves when using an angle grinder. Again, this is because metal shavings can be thrown at incredible speeds and could easily cut through the skin if they hit bare flesh. Gloves are also great to withstand minimum pressure or weight.
  • Respiratory protection: Gas-powered grinders produce a lot of harmful dust particles during operation. While wearing respiratory protection won’t necessarily prevent all the dust from getting into your lungs, it will certainly help protect them more than not wearing any protection at all.
  • Padded protection: Always ensure that the correct type of item you are grinding is secure and cannot move around during the process. This will make the task safer and easier to perform should your hands slip off of it. The last thing you want is for the grinder disc to strike your leg or arm while it’s spinning at maximum speed!
  • Tighten Discs Properly:  Until you have a Metabo angle grinder with a particular mechanism for tightening and releasing your grinding discs, you should have received a special pin wrench with your angle grinder. If you lose your wrench, we have an adjustable spanner nut wrench that fits any correct angle grinder size and is built specifically for this.
    Always use the wrench to ensure a snug fit when tightening the wire wheels or disc. Many individuals tighten their abrasive wheels by hand, which might be harmful when used. There’s no need to make it exceptionally tight; just snug enough that you couldn’t do it by hand otherwise.

How can I use an Angle Grinder Safely?

  • Two main measures can be taken to ensure that you use an angle grinder safely, knowing how much pressure should be applied during work and wearing PPE.
  • The amount of pressure required depends on what material is being cut, drilled, or ground away by any type of disc. For example, it is possible to cut through metal with sharp edges of an angle grinder, but the speed required is far higher than grinding wood.
  • One additional thing that should be taken into account is whether you are cutting or grinding material. Cutting requires a coolant spray because it will heat up very quickly and cause burns to your hands. Grinding bends or flattens out the hot metal without a period.


Can Sparks from an Angle Grinder start a Fire?

Of course, sparks can smolder and cause fires. For this reason, you should never cut near flammable materials such as sawdust or hay because they can have high risks of injury. Also, never position yourself where sparks may fly towards you and ignite your clothing or hair. Always wear protective clothing on while working with a grinder

How common are Angle grinder accidents?

They are relatively common, considering that they are handy tools. According to Health and Safety Executive (HSE) statistics, there were over 30,000 incidents involving angle grinder injuries or similar equipment between 2002 and 2012.


Angle grinders can be dangerous if not used safely. Therefore, wearing the correct personal protective equipment is important and following all angle grinder safety precautions and guidelines when using an angle grinder. Sparks from an angle head can start a fire, so it is essential to be aware of your surroundings at all times. Have a safe grinding and cutting experience.
