What Is an Angle Grinder?

Also known as a side grinder, an angle grinder is a handheld tool that spins various attachments at very high speeds. These devices can be used to clean up welds, cut hard materials, and shape soft materials. Angle grinders come in countless shapes and sizes, and there are now thousands of attachments on the market.

Just like many other power tools, care must be taken when using an angle grinder. Depending on what types of materials you are working with, your angle grinder might produce sparks or airborne toxins.

Before using your very first angle grinder, you should familiarize yourself with all of the features and accessories. Most modern angle grinders come with at least a few safety features including emergency braking systems and anti-kickback clutches.

What else?

You also need to practice with your angle grinder on test materials before you work on a finished project. Learning how to properly use your angle grinder will reduce your risk of a serious accident or an expensive mistake.

Buyer’s Guide – Main Features to Consider

  • Disc/Wheel Size

One of the most important specs to consider is the disc or wheel size. The size of the disc will determine how wide of an area you can work on at once or how deep of a cut you can make.

Smaller angle grinders are usually compatible with 4-1/2-inch attachments, and they are a great option for grinding concrete, cutting through metal pipes, and other basic jobs. Larger angle grinders require more strength, but you will be able to work with thicker materials.

  • Power Supply

Angle grinders can either be plugged into an outlet or powered with a battery pack. Cordless angle grinders tend to be much easier to use, but you will need to have high-quality batteries and a compatible charger.

Corded angle grinders, on the other hand, pull directly from an AC or a DC power source. With a corded angle grinder, your project will need to be relatively close to a power outlet or generator.

  • Power

The overall power of your angle grinder will determine how easy it is to work with certain materials. Most general-purpose angle grinders have motors that are between 3.5 and 6.5 amps. That will provide you with plenty of power when working with steel, concrete, tile, and stone. You will also notice that the vast majority of angle grinders have an RPM rating as well.

That number tells you the maximum number of revolutions that the disc or wheel will do per minute. Higher RPM angle grinders remove more material, but they aren’t suitable for finesse work.

back to menu ↑

How To Use

How you use your angle grinder depends on what type of job you are doing. No matter what project you are working on, you should always make sure that you have read the user’s manual and are wearing the proper safety gear.

After unplugging your angle grinder or removing the battery, you can attach the cutting wheel or disc. Once the attachment is secure, you should then get a good grip with both hands before turning the device on. As with most other power tools, you must always try to make short or shallow passes.

During each pass, you need to apply consistent pressure at all times. Removing too much material during one of your passes could completely ruin your project or jam the disc.

The best way to get used to an angle grinder?

Practice with as many different attachments and materials as possible. Your angle grinder will “pull” in certain directions, and you must be ready for those movements. You should also make sure that you are using the proper attachments at all times.

back to menu ↑

Safety Features to Look for in the Best Angle Grinder

No matter what angle grinder you decide on, you must be cautious and safe when handling one of these tools. Side grinders are very dangerous when used incorrectly, and major injuries can happen in the blink of an eye if you aren’t careful. Before turning the angle grinder on, you should always be wearing safety glasses and ear protection.

Unlike most other tools that rotate, operators must always wear high-quality gloves when using angle grinders. Angle grinders vibrate quite a bit, and gloves will give you more control over the tool.

In addition to protection for your eyes and ears, you also need to make sure that you aren’t breathing in any airborne contaminants. Most experts suggest wearing full respirators that cover the mouth and nose when using an angle grinder.

Your mask should be specifically designed for fine airborne contaminants such as concrete dust. Whenever possible, you must try to work in a well-ventilated area as well.

FAQ’s

How do I pick an attachment for a particular job?

You will need to do some research before you carry out any new job. Choosing the right cutting wheel or disc is going to improve your safety and make your project much easier. Grit discs are usually used to cut substances like stone and metal bars. They tend to be much more affordable, but they might break after a few uses.

Diamond discs are a bigger investment, and they often last for quite some time as long as you properly care for them. Abrasive attachments are typically used to sand, polish, or buff.

Do angle grinders require much maintenance?

If you want your angle grinder to last, then you certainly need to properly maintain it. The easiest way to extend the service life of an angle grinder is to thoroughly clean it with a rag after every use. You should also take breaks while you are working to prevent overheating.

Some angle grinders come with cleaning and maintenance kits, and you must read the user’s manual before using those kits. You should never attempt to take apart or fix a damaged angle grinder.
