So you've just purchased an angle grinder for your own DIY projects or for your team's upcoming projects on site. Anyway, you might be wondering what you can accomplish with this tool in hand. Of course, you probably know that you can use this tool in its default mode for grinding metal.

But what else can you do? After all, it is one of the most versatile tools that exist, much more than thebench grinderFor example.

This guide will delve into the types of tasks you can successfully complete using an angle grinder. Many of these uses are related to metallurgy and manufacturing, unsurprisingly. But at the same time, you might be surprised how this tool can also be used for carpentry and masonry work.

With all these uses in mind, you're sure to find an opportunity to take your angle grinder on almost any project in the future.

4 uses of the angle grinder in metallurgy

Before moving on to the tool's more specific uses, let's look at metalworking.


First, let's look at the most obvious usage.

Your unit will likely come packaged with at least one abrasive wheel accessory. With this disc, you will be able to remove access material from the surface of metallic objects. In practice, these abrasive discs allow you to perform a range of important manufacturing jobs, including deburring, smoothing and chamfering.

Keep in mind that while this is the original purpose of an angle grinder, it does come with some restrictions.

In particular, grinding can cause the used wheel to heat up quickly due to friction. So anyone who intends to do a lot of roughing with an angle grinder should have some discs to turn while working. Otherwise, they risk damaging their blades beyond repair.

Paint and rust removal

Angle grinders are also great for removing all types of materials other than metal. For example, with a wire wheel attached, an angle grinder can be turned into a paint removal machine. To that end, these tools are routinely used by professional mechanics and body artists to complete even the most complex paint jobs.

In this capacity, an angle grinder can completely remove paint from a car body in just a few passes.

However, that is not all.

With the same wire wheel, an angle grinder can also be used to remove rust from a corroded metal part. This is particularly true when the oxide layer is quite thin and has not penetrated the inner structure of the metal. Auto mechanics also use their angle grinders for this purpose, especially when restoring vintage cars and auto parts.


Let's say you have a finished aluminum or steel part that you want to polish before you assemble it in its final location. But without an electric polishing tool, you could spend hours hard at work trying to restore your metal's shine.

However, this need not be the case if you have an angle grinder with a grinding head. With these two parts combined, you can polish a wide variety of metals without investing in a single-use power tool.

Note, however, thatusing an angle grinder for this purpose takes a little extra workFrom you. Traditional polishing tools are designed to apply pressure while rubbing. Angle grinders don't do this by default, so you'll need to apply light pressure to get the most out of their grinding potential.

Perhaps the second most frequent use of an angle grinder is its ability tocut metal. Specifically, an angle grinder equipped with a tapered cutting blade is fully capable of cutting small to medium gauge metal with relative ease.

In this capacity, angle grinders are commonly used on professional job sites, especially when it comes time to cut sheet metal or rebar.

However, cutting with an angle grinder is easier said than done.

As you'll quickly notice, you'll often need to make several passes across the surface of a piece of metal before cutting through it completely. Also, cutting metal with an angle grinder is bound to throw up a fair amount of debris, not to mention sparks.

Therefore, you must be fully equipped with PPE that covers your skin, eyes, mouth and ears.

2 uses of angle grinders in joinery and carpentry

Next, let's take a look at using an angle grinder when working with wood in one form or another.


The practical uses for angle grinders in a woodworking shop are few and far between. However, some amateur woodworkers can attest to this tool's ability to effectively sand a rough cut of wood.

To do this, you will most likely need to take a flap abrasive disc, which is traditionally designed for grinding metal. Then carefully run it over the rough surface of the wood until it is perfectly smooth.

In reality, though, this sanding method is technically overkill. In fact, you run a much greater risk of chipping the surface of your piece of wood with one of these discs.

Instead, you should consider usingan oscillating multi-tool with a sanding attachmentoa dedicated sander. This can effectively cut your sanding time in half.


Some carpenters have also claimed success cutting rough wood with an angle grinder and a metal cutting wheel in hand. While this is theoretically possible, the result is likely to be unsatisfactory. Still, if you want to learn how to do this,read this guide.

Also, due to the edge design of metal cutting wheels, you are at a much greater risk of bursting when cutting in this manner.

2 uses of the angle grinder in masonry and concrete work

While an angle grinder isn't an ideal tool for woodworking, it can certainly come in handy when working with masonry and concrete.

Cutting tiles and other masonry materials

Many professional bricklayers and tilelayers have an angle grinder on hand to perform a wide variety of cutting tasks. Specifically, a skilled user can mount a diamond cutting blade to these tools and use them to efficiently cut through brittle tiles as well as thick, dense cinder blocks.cobblestones.

Exceptionally, cutting tile and masonry materials in this way can be done "dry". This is opposed to so-called "wet cutting" which can be cumbersome and time consuming in many masonry environments. Keep in mind, however, that cutting drywall materials with an angle grinder is tricky business. It tends to release a lot of debris, so the proper PPE should always be worn for the mouth and eyes.

grout removal

Many angle grinder owners are unaware that this tool can be used to efficiently remove grout. In fact, it can, making it a great asset to bricklayers who are deconstructing an existing structure.

This job requires a finishing wheel, which is often diamond-tipped to give it more abrasive power. This construction also ensures that the old mortar is sprayed effectively without chipping the surrounding blocks.

As with cutting tile and stone with an angle grinder, those involved in removing grout with an angle grinder must be fully aware of the amount of waste it generates. Grout dust is particularly harmful if inhaled or if deposited in the eyes.

As such, this job also requires eye and mouth protection at all times.

Other Common Uses for Angle Grinders

Finally, let's look at some uses for angle grinders that are unrelated to the above.

Sharpening metal tools

Sharpening metal tools is necessary from time to time. But many DIYers simply don't have access to a bench grinder that can make that happen. In a pinch, an angle grinder can be used to achieve the same purposes.

(Video) How to Remove Paint with a Grinder

As long as you have a fine grinding head attached, this tool can return your tools to a like-new edge.

However, sharpening tools with an angle grinder is not an easy task. This is because it requires the user to carefully tilt the entire unit and maintain that angle while grinding the edge. A shield plate would also be prudent because this task is likely to produce a shower of sparks.


Although the practice is not as common, angle grinders can also be used to do some drilling work. However, to do this, you will need to purchase a specialized chuck that can be mounted on the accessory spindle of your angle grinder.

With this assembled, you will be able to attach a variety ofspecialized drillsthat can blast their way through everything from wood to brick.

Most of the time, you'll want to use the strongest bit you can get when drilling with an angle grinder. This is because you want to maximize drilling efficiency and minimize friction whenever possible. This can usually be done with a carbide-tipped bit, similar to those used for traditional drilling.

Diamond-tipped angle grinder bits are also available for those who intend to use their angle grinder for this purpose on a regular basis.


Can you believe how much you can do with just one angle grinder?
