A compact device used for polishing, grinding, and cutting metals and hard materials is referred to as an angle grinder or disc grinder. Angle grinders are capable of slicing through concrete. Hence, angle grinder is a powerful and very risky tool in metalworking.

Given their power, angle grinders have the potential to injure both their operators and anybody nearby seriously. Understanding angle grinder safety precautions is therefore essential if you wish to maximize the use of your power tools without suffering any injuries. Here are some pointers for getting the most out of your angle grinder.

Top 10 Angle Grinder Safety Tips

1. Wearing Protective Gear

Wearing PPEs is the first and foremost step in taking safety precautions. Always wear appropriate protective gear prior to working with angle grinders. This includes gloves, face shields, goggles, etc. Keep your long hair tied up, and don't wear loose apparel.

2. Check For Damages

Before using, inspect the damages. Accidental drops are unavoidable. The possibility exists that someone else completed it instead of you.  You can examine the attachment to see whether it is damaged or if using the grinder is dangerous. Examine the blade first, regardless of whether the wheel is new or worn.

Cutting discs could get dropped accidentally while being stored or damaged during delivery. 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

Always warm up the machine before each use or if you're taking it from another, using it after a break, or if you're using it for the first time. Ensure to run the angle grinder at least for a minute or two till it reaches its full speed. You also have the chance to check whether the grinder is in good working order.

4. Avoid Working in Flammable Areas

Avoid using angle grinders near anything that can easily 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. A fire may result from sparks landing on any combustible material. As a result, it's advisable to take precautions and store flammables at a safe distance.

5. Start Slow

Speed is an important factor to consider while operating a grinding wheel. Generally speaking, start slowly and increase the speed gradually until you are happy. Each grinding blades require a different operating speed. If you are unclear about the proper speed for your grinder-blade combination, ask your seller.

6. Avoid Customizing Your Tool

Don't customize your tool without first consulting the manufacturer, who may provide you with further information on what will and won't work with your angle grinder. Ensure only to use the attachments that go perfectly with the grinders. However, if you still wish to modify your grinder for any reason, speak with the manufacturer or first read the user manual. If not, you put yourself and other people in danger. 

7. Properly Tighten The Discs

A unique pin wrench should have come with your angle grinder. Your angle grinder grinding disc can be tightened or loosened by using this wrench. In case of losing the wrench, there is an adjustable spanner nut wrench which is made particularly for this and is perfect for any angle grinder size. For a secure fit, make sure to use a wrench to tighten the disc or wheel. The majority of customers manually tighten their wheels, which could be dangerous while in use. Make sure it's snug enough that you can't do it by hand but not too tight.

8. Selecting The Proper Wheel Size

Selecting the appropriate grinding wheel for your projects is crucial. Using the incorrect blade for your power tool can harm both the blade and the grinder, putting your safety at risk. Consider the necessary dimensions before choosing the type of wheel. Larger wheels are made for heavy-duty industrial purposes, whereas smaller wheels are appropriate for non-industrial uses. Carefully examine the material prior to selecting the correct angle grinder disc for your projects.

9. Operating Grinder With Two Hands

Keeping total control over your angle grinder is one of the most important safety considerations. Be sure to hold the grinder correctly with both hands. When using two hands to operate the machine, you have better control. Always keep in mind that one hand should be kept on the handle and the other one on the back of the grinder.

10. Modify the RPMs to reflect the wheel allowance

RPM is another crucial factor in your Angle grinder. The higher suggested RPM should be clearly mentioned on the packaging or in the product description for each grinding wheel and disc. Never use an abrasive tool with a lower recommended RPM than what your angle grinder can handle.

Only the designated speeds are intended for use with the abrasive discs.  When you apply excessive force to grinders running at high speeds, it will result in damaging or breaking them.
