It can also be used for sanding, polishing, or sharpening different materials. Indeed, it’s a very useful tool to have in your toolbox.
But you should know that using an angle grinder comes with safety risks, especially if you’re using a grinder that doesn’t come with any safety features.
This is why before buying an angle grinder, you should make sure to do your research and look for something that can ensure your safety while also delivering excellent performance.
Aside from the safety features, there are several other factors that one must take into consideration when buying an angle grinder.
You also need to consider the disc size, motor, power source, RPM, and more. Of course, it must be durable as well and able to withstand rigorous use.
To help you with this, we came up with this guide where we talk about the different factors to consider when buying angle grinders. We have also included a list of the best angle grinders.
Things to Look for When Shopping for the Best Angle Grinder
So, how do you choose the best angle grinder to buy? Below are some of the most important factors that you must take into consideration in order to find the right grinder to use for your projects.
Most of the angle grinders work with batteries. But there are also corded air-powered models. Before buying a grinder, it is best to read corded angle grinder reviews to find out which of these corded models is truly the best.
Going for cordless and battery-powered units is a good idea since they are able to access tight spots. But their operation is limited to how much power is in their battery.
When the battery dies, then your work will be interrupted. The best-corded angle grinder is a great tool to buy. It will operate for a long time if it’s plugged into a power source.
But then you’re also limited on the area to use it since the cord will restrict your movement. Also, it can be a hassle to keep on looking for power outlets whenever you need to use the grinder.
The wheel or disc of the grinder indicates the power and overall capacity of the device. Angle grinders with large discs are generally more powerful. On the other hand, smaller discs are more reliable for focus jobs.
It can also be used to accomplish certain tasks that would need precision. When deciding on the size of the grinder, think about the type of work that you need to accomplish using this tool.
Are you going to use it for smaller spaces and tight angles? If so, then the best angle grinder for you to buy is a model that’s more compact in size.
For those who need to accomplish high work volume, then getting a model with a larger disc can serve you best. The disc size is available in different variations, which is usually between 4 to 9 inches.
The speed of the grinder is another important factor to think of. Keep in mind that the speed can also affect the grinder’s overall performance.
The average model will have a speed of around 500 to 10,000 rpm. Faster speeds are able to produce desired results fast, especially when used by an experienced handyman.
But if you’re not that expert in handling grinders, you might find it difficult to handle those with very fast speed. Thus, the best angle grinders to buy are those with variable speed settings.
This device will allow you to choose from different speed settings, which optimizes the tool for the particular task you need to perform while making sure it’s within your skill level.
An ergonomic tool is a good investment. These tools are designed to specifically fit into human hands and are therefore easy for everyone to use.
Of course, angle grinders that are ergonomically designed are more comfortable to operate. Above all, they will protect you from injuries including carpal tunnel syndrome.
These days, you’ll find plenty of power tools with ergonomic design. In fact, some of the best grinder brands promote their products as ergonomic.
But this isn’t something you should take for granted. Remember that when working with power tools like angle grinders, comfort should be your number one priority.
Even if you want an angle grinder with a powerful speed of 10,000 RPM, you definitely don’t want the tool to start working at this speed right away. Therefore, you should choose a model with a slow start mode. It’s definitely much safer to use.
Some of the angle grinders in the market are equipped with special guards that can keep your hands protected from sparks and splinters.
This feature is not really necessary but it’s a great safety feature, especially for first-time users. You’ll also find some models that come with adjustable hand-guards that you can alter in order to suit the tasks you’re working on.
It’s normal for power tools to get into contact with bags of dust, especially the angle grinder that is used for cutting different materials.
Aside from accumulating lots of dust, the grinder often ends up being smothered with dust and other debris. The dust could seep into the inner workings of your grinder and this could potentially damage the tool.
This is why the best angle grinder to buy is one that comes with a dust protection element. It usually comes in the form of a special seal or a component that will funnel the dust away from the inner workings of your grinder.
The price of angle grinders varies greatly. But the good news is that the angle grinders are among the most reasonably priced power tools on the market. In fact, you can get a decent angle grinder at a fairly modest price.
So even if you have a limited budget, you can still find the best angle grinders at very reasonable prices.

Angle Grinder Uses
First, let’s talk about the angle grinder and why this tool is popular. Angle grinders are very versatile, which means they are capable of doing lots of tasks. You will find them in different sizes although the most popular ones are the 4-inch and 4 ½ inches.
The angle grinder’s main task is to grind metals, cut rebar, stucco, and tiles. It can also be used for sanding, polishing, routing out mortar, and sharpening.
Given the many tasks that this tool can accomplish, it’s easy to see why it’s considered an invaluable tool to have in your workshop. Let’s take a closer look at the various ways that you can use the angle grinder:
One of the most important tasks of the angle grinder is to cut the rebar. You can use the tool to cut rebar that’s in concrete and to attach the metal cutoff. Just make sure the tool is tightly secured when doing this.
Place the cutoff wheel into the metal and let the tool’s weight control the drop. Some people use a hacksaw for this, but the angle grinder is more efficient at doing this task.
Angle grinders can be used to clean rust from certain tools. It can also remove caked-on cement. When using the tool for cleaning, make sure the brush spins away from the tool’s edge to avoid kickback.
The angle grinder is also very useful for sharpening the blade of your other tools. Simply secure the blade using a vise or hand clamps and then position the grinder.
Make sure you adjust the blade guard to keep the sparks from getting into your body or face. Align the grinding wheel to the angle of the blade and start the grinder by moving the wheel into the blade to sharpen it.
Grind Out Mortar
The grinder is also useful for grinding out loose and old mortar. For this, you should make 2 to 3 ½-inch deep drills in order to clear the joint. Make sure you keep it about 1/8-inch away from the brick.
With the use of the grinder’s diamond blade, you’ll be able to cut through the middle of the tile. This is very useful when you need to cut holes to give way for an outlet.
In this case, you must first warm an outline for the size and then secure the tile into your workbench using a clamp.
Frequently Asked Questions (FAQs)
Can angle grinders cut metal?
As mentioned, angle grinders are very versatile tools that you can use for various tasks, such as cutting rebar, stucco, and tile.
But when working with metals, you need to use a certain type of disc or wheel for the particular type of metal that you are working on.
Generally, a cut-off wheel is required for cutting through metals. This is basically a thinner version of the grinding wheel and is specifically designed to cut through metals such as pipes, sheet metals, and even dimensional steel.
How can I remove the disc without tools?
Using your palm, strike the disc towards the disc arrow’s opposite direction. This will loosen the nut enough for you to remove it with the use of your fingers.
How can I remove the angle grinder disc?
It’s easy to remove the disc of the angle grinder. With a little bit of practice, you can do it in only a few minutes. Also, there are many ways on how to remove the disc, depending on the tools and your preferences.
First, make sure the power is totally shut off before you remove the disc. If you’re using a corded model, remove the plug from the outlet.
For cordless models, take the battery off before you remove the disc. Doing so can lighten the tool, making it easier and safer for you to handle.
How can I remove the disc from the vice grip?
Connect the vice grip securely into the bolt that holds the disc in the drive. As you keep the vice grip in place to prevent the disc from spinning, attach a screwdriver into the holes that are in between the motor and the disc.
Gently pull the screwdriver towards the disc arrow’s opposite direction. If it doesn’t loosen immediately, you can use a hammer to force the screwdriver to turn.
How can I remove the disc with spanners?
If the angle grinder you’re using comes with factory spanners that are similar to flattened wrenches – one is normal while the other is a 2-pronged fork, then you can use them to remove the disc.
Simply insert the prongs into the holes in the drive bolt and use a wrench-like spanner to secure the bolt into the base of the disc. As you hold the spanner in place, drive the pronged spanner towards the opposite part of the disc arrow.
Take note that you might also find a button in the grinder that can hold the disc in place. Drive the nut until the disc is completely removed from the tool.
Can I use the angle grinder as a polisher?
As a versatile tool, the angle grinders can be used to accomplish a wide range of projects and that includes grinding and cutting metals. But you can also use the tool for cleaning or polishing.
When using the grinder to polish metal, you must attach a buffing pad or a polishing wheel. This can help restore the metal’s original luster. You can also use a disc for high-grit grinding if the metal is marked up.
The disc will smoothen the metal first and that’s when you can start polishing or cleaning. You can also use polishing compounds to help with the task. But make sure you choose something that’s specifically made for grinders.
When buying an angle grinder, you need to make sure you are getting something that you can certainly rely on. It should be powerful enough to carry out different grinding tasks and must be comfortable enough to handle.
