10 Angle Grinder Safety Tips You Must Know

Angle Grinder Safety Tips

Angle grinders, also known as disc grinders or side grinders, are hand-held machines that are used to cut, polish, and grind metals and other hard materials. Angle grinders are capable of slicing through concrete. As a result, it is both a strong and dangerous tool in the metalworking world.

Angle grinders can cause terrible bodily damage to their operators and others around them due to their power. As a result, knowing angle grinder safety guidelines is critical if you want to get the most out of your power tool without injuring yourself. Here are some pointers for getting the most out of your angle grinder.

Top 10 Angle Grinder Safety Tips

1.   Wearing Protective Gear

Wearing correct safety gear before using angle grinders is the first and most important safety precaution. A full-face mask, hand gloves, eye and hearing protection, suitable attire, natural fiber clothing, and apron, if needed, are all forms of protective gear. Avoid wearing loose clothing and tying long hair.

2.   Check For Damages

Before using, inspect the damages. Accidental drops are unavoidable. It's possible that you didn't do it yourself and that it was done by someone else. You can inspect the attachment to check whether it has been damaged or if the grinder is unsafe to use. Whether you're dealing with a worn or new wheel, always inspect the blade first. Cutting discs may be damaged during delivery or dropped while being kept by accident. Check for chips, cracks, and other damage before using the disc to ensure that it functions to its maximum ability and keeps you and others safe.

3.   Grinder Warm-Up And Inspection

Allow at least one minute for the angle grinder to run with the attachment attached before using it, whether you're picking it up for the first time, returning from a break, or taking it from another worker. This allows the machine to warm up and reach full speed, as well as allowing you the opportunity to feel, hear, or see if the grinder is in good operating order.

4.   Avoid Working In Flammable Areas

Angle grinders should never be used near anything that can catch fire. When using an angle grinder, any items that can readily catch fire, such as aerosol or gas cans, or an oily rag, should be avoided. Angle grinders, especially when working with metals, can generate a lot of sparks. If the sparks land on combustible materials nearby, it will create a terrible fire. As a result, it's advisable to take precautions and store flammables at a safe distance.

5.   Start Slow

While using your grinding wheel, it's vital to set the speed. As a general rule, begin slowly and gradually raise the speed until you are satisfied. Different operating speeds are required by different grinding blades. Consult your vendor if you're unsure about the appropriate speed for your grinder-blade combination.

6.   Avoid Customizing Your Tool

Some people wish to personalize their angle grinder, however, this is not recommended. Before personalizing the tool, make sure to ask the manufacturer so that they can tell you what works and what doesn't. Make sure you only use the attachments that came with the grinders. If you still want to change your tool, read the manual or contact the manufacturer, otherwise, you risk harming yourself and others.

7.   Properly Tighten The Discs

A unique pin wrench should have come with your angle grinder. This wrench is used to tighten and loosen angle grinder grinding discs. If you lose your wrench, they have an adjustable spanner nut wrench that fits any angle grinder size and is built specifically for this. Always use the wrench to ensure a tight fit when tightening the wheel or disc. Many individuals tighten their wheels by hand, which might be harmful when they are in use. There's no need to make it very tight; just snug enough that you couldn't do it by hand.

8.   Selecting The Proper Wheel Size

Choosing the correct grinding wheel for the job is crucial. Using the incorrect blade for your power tool can harm both the blade and the grinder, putting your safety at risk. Before selecting the type of wheel, determine the size you require. The discs normally measure between 4.5 to 9 inches in diameter. Smaller wheels are suitable for non-industrial applications, whereas larger wheels are designed for heavy-duty industrial applications. Examine the material of your project carefully before selecting the appropriate angle grinder disc.

9.   Operating Grinder With Two Hands

Keeping perfect control of the grinder at all times is one of the most crucial safety considerations. It's vital to keep both hands on the power tool in the correct positions at all times. You have a lot more control and leverage with two hands on the machine. Always keep one hand on the handle and the other on the rear of the grinder.

10.   Adjust The Rpms To The Wheel Allowance

RPMs are another crucial feature of your angle grinder. The maximum suggested RPM for each grinding disc, wire wheel, and other abrasive should be specified on the abrasive's face, packaging, and product description. Never use an abrasive tool with a lower recommended RPM than what your angle grinder can handle.

The abrasive discs are only designed to work at the speeds specified. When you utilize the discs at greater speeds, you risk damaging them by applying more force/pressure than the disc can safely take.


Angle grinders with high power can cause significant mishaps that can injure you and others. As a result, keeping both others and yourself safe when using power tools should be your primary responsibility. This can be accomplished by following angle grinder safety advice.
