Why Do You Need a Variable Speed Angle Grinder?

If you want to buy a grinder, you probably already have a project in mind. Whether you want to focus on one particular material, or on a wide variety of materials to be cut, sanded, polished, or cleaned, we can help you. The choice of the right grinder is partly based on your needs and the preferred materials. Here are recommendations of the best grinder models according to the material to be worked on.

I Want to Cut Steel
With a grinding machine, it is possible to cut/saw thin layers of steel. Depending on the cutting depth, a 125 or 230 mm grinder should be chosen.

For a 125mm grinder, a 125mm diameter cut-off wheel with a thickness that can vary from 1 to 1.6mm is used.
For a 230mm grinder, a 230mm diameter cut-off wheel with a thickness of up to 2mm is used.
The thickness of the disc is chosen according to the desired result. The thinner the disc, the sharper and more precise the cut, but the disc is brittle, so inclined cuts are avoided. A thicker disc is used for coarse work.

Caution: Be sure to wear protective glasses because the contact of the disc with the metal generates sparks. It is also advisable to have no flammable products around the work area. In general, the usual precautions are written on the disc or its packaging.

I need to Grind Steel
Is your job to grind steel and clean a metal surface (e.g. after welding)? Then you need a grinding machine with high power. It will guarantee safe movements, and real resistance to the material, all for greater precision.

Choose between a grinder, an angle grinder, or a straight grinder. It is recommended to fix the workpiece to be ground firmly with a vice or a clamp. Then use the right abrasive for easy work. Aluminium oxide for high-strength steel and silicon carbide for low-strength steel.

I need to Cut Concrete
When cutting concrete, it is absolutely necessary to use a diamond blade. A diamond disc costs more to buy but wears out less quickly.

Depending on the cutting depth, you should choose a 125 or 230mm grinder on which a 125 or 230mm diameter disc is fitted.

It is possible to use discs with segmented edges. The work will be faster but the result will be less fine… These discs are mainly used in masonry.

Caution: a diamond disc does not sharpen but it is possible to clean it by cutting chipboard. This allows you to maintain its full efficiency.

I have to Grind Concrete
If you want to grind concrete, you need a grinder powerful enough to handle this hard and tough material. Ideally, the work should be carried out on both vertical and horizontal surfaces, so you have a lot of freedom of movement. An angle grinder is recommended for its versatility, to be embellished with a segmented diamond disc.

Depending on the disc, you can change the appearance of the concrete surface, clean or dig. Diamond and segmented discs are designed to cut marble or concrete thanks to their good resistance.

I Want to Cut Tiles
To cut tiles, you need a grinder that can hold different discs. Indeed, if you plan to work with tiles, the right disc to hold will not be the same depending on the thickness of the tiles and their hardness. This is why it is important to have a grinder capable of holding a wide variety of discs.

A smooth or continuous segment diamond disc is recommended for cutting tile to ensure a clean, burr-free cut. You can also choose diamonds and bakelite discs. Remember to choose a grinder with large diameter discs (230 mm) if you are cutting large tiles.

I need to Grind Glass
A straight grinder with a grindstone is recommended for grinding glass. Be careful, grinding glass is not the same as “cutting” glass. Here, with a grinder, the aim is to reduce the size of the glass, change its appearance, or to polish sharp edges.

If you venture to cut glass with a grinder, you will create splinters, break the surface, and hurt yourself. Choose a very fine grain and soak in water regularly for precise work.


What energy will your grinder feed on?

To differentiate the grinders, and choose the right model according to your need, it is necessary to be interested in the mounting of the discs and the variety of accessories. It is also the energy of the grinder which is to be monitored and its power. Depending on the energy that powers your grinder, you will not have the same rendering. And in terms of power, ditto: the more powerful it is, the less a grinder will need to turn fast and hard to perform its action.

Best Variable Speed Angle Grinders Comparison Table

Type Of Angle Grinder

Electric Grinder

Electric Angle Grinder

Electric grinders are the most common. However, if the majority of machines use this energy, you have to look at the power level. Expressed in watts (W), it varies depending on the work you want to do. You will find models with a variable power range.

Grinders with low power (150 to 400 W) are to be reserved for small jobs, and for occasional use (these are generally mini-grinders).

For sanding, choose a grinder with a power between 600 W and 1000 W. Beyond, and up to 2000 W and more, we find the grinders for the most demanding works, and in particular the structural work.

Cordless Grinder

Cordless Angle Grinder

An electric grinder can be wired or battery operated. In this case, we speak of a cordless grinderWireless models are very practical on construction sites and allow more working comfort. Better, without wire, you have the possibility of working on a site that does not have electricity.

Beware however of some limits. Cordless, a grinder cannot offer you maximum power, and autonomy is, logically, limited. You will only find models of grinders 115 and 125mm in “cordless”.

Pneumatic Grinder

Pneumatic Angle Grinder

The pneumatic grinder is very popular with some professionals. It is the favourite grinder model for welders and metalworkers. Why? Because the compressed air system and the air compressor provide a lot of power. Better still, stopping and starting are done instantly.

A top grinder for construction sites, which also resists humidity and has a low weight. The ideal grinder? The pneumatic system brings some limits: it is indeed necessary to compose with the pipe which connects the whole to the compressor, which reduces the handling.

Price of a Grinder: What Budget for What Use?

What is the price of a grinder? What budget to spend on the purchase of a grinder? Depending on the technology, the price of a grinder will not be the same:

  • Angle grinders are available for 20 or 30 $. The most complete models, the most powerful, and which will offer true versatility will ask you for a larger budget. You can find very complete models for 150 to 200 $, with the top range going to 400 $ or more.
  • The most accessible straight grinders are offered at a price of 90 to 100 $. You can have a brand model for this price, with a power of 400 W. For 250 to 300 $, more powerful machines are available (650 to 900 W).
  • For a mini-grinder, prices range from 30 to 200 $. A more limited price range is explained by the more limited performance of these grinders.

10 Main Applications of Variable Speed Angle Grinder

The three main functions of an angle grinder are grinding, grinding, and cutting.

When cutting, the angle grinder operates at a very high speed, this speed makes cutting easier and ensures greater precision.

With a suitable nozzle set, any scratched metal can be repaired and polished. What do you think about buying an angle grinder? So it’s important that you look at all the ways it can help you.

These versatile devices have many applications.

1. Color Removal

In body shops, you will most likely find an angle grinder because it is used to remove paint. The angle grinder removes old paint without damaging the underlying metal.

2. Rust Removal

The angle grinder can also remove rust. To remove a layer of rust you will need a brush or a metal wheel. Once the rust has been removed, the surface must also be prepared for a new coat of paint.

This allows you to store the metal under the grid.

3. Cutting of Ceramic Tiles

The angle grinder is ideal for cutting ceramic tiles and other items. You cut the edge clean and tidy.

4. Removal of solutions

With the angle grinder, the mortar can be removed easier and faster. This tool also reduces the risk of bricks shredding each other when the mortar is being cleaned.

5. Stone carving

As we already know, the angle grinder is able to make smooth and beautiful cuts, making it ideal for cutting stone. If you need extra mobility, you should opt for a smaller grinder because its compact dimensions help you to cut small and precise workpieces.

6. Metal cleaning

Just like you can clean metal with an angle grinder and de-rust trolleys. A wire brush is a suitable tool here because it can easily clean your metal tools and shovels.

7. Metal cutting

In addition to cleaning the metal, you can also cut it with an angle grinder. The advantage is that angle grinders are compatible with all types of metals. The use of an angle grinder allows the metal to be cut, making it naturally good for cutting metal.

8. Tool grinding

The ideal alternative to a bench grinder for grinding tools is the angle grinder. However, you do need some knowledge of tool management and checking the proper functioning of the equipment.

9. Wood carving

You can cut out a wooden object with the wire rings. As angle grinders, they are ideal for wet forming, e.g. for the production of tables or table legs. Don’t forget that angle grinders aren’t good enough for hard work, so you need something else for that.

10. Planed wood

Finally, you can machine the wood with the wire wheel. The threaded wheel can also be used for other planning tasks.

Points of Attention When Purchasing a Variable Speed Angle Grinder


When it comes to price, budget is always a concern for consumers. With a variable speed angle grinder, the price can range from $30 to $200. It all depends on the features that you are looking for in the tool. For basic use, a model that is less expensive will work just fine. However, if you need more features or power, then you will have to spend a little more. Keep in mind though that you do get what you pay for and a higher priced model will likely be of better quality.

Type of Angle Grinders

There are three types of variable speed angle grinders: cordless, corded, and pneumatic. Cordless angle grinders are powered by a battery, while corded angle grinders are plugged into an electrical outlet. Pneumatic angle grinders use compressed air to power the grinder.

Cordless angle grinders are the most popular type of variable speed angle grinder because they are portable and easy to use. They come in a variety of sizes and can be used for a variety of applications. Corded angle grinders are more powerful than cordless angle grinders and can be used for heavier applications. Pneumatic angle grinders are the most powerful type of angle grinder and can be used for the toughest applications.


When it comes to power tools, there are a lot of different factors to consider. Speed is one of the most important, as it dictates how quickly you can work and the level of precision you can achieve. With an angle grinder, you have a variety of speed settings to choose from, depending on the project at hand. The average speed range for an angle grinder is 3,000-10,000 RPM, but some models offer more or fewer speed setting options. It’s important to choose the right speed for the job to avoid damaging the tool or your workpiece.

Disc Diameter

The disc diameter range on a variable speed angle grinder is 6”-8”. This size is important to note because it affects the power of the tool. The larger the disc, the more power it takes to rotate it. So, when looking to buy an angle grinder, make sure to take into account the size of the disc that you need for your project.

Safety Features

Variable speed angle grinders offer many features to make the grinding process safer. One safety feature is a slow start. When the grinder is turned on, it starts slowly and then speeds up. This prevents the operator from being shocked by the sudden start-up of the grinder. Another safety feature is an anti-kickback paddle switch. This switch stops the grinder if it begins to kick back. This prevents the operator from being injured if the grinder kicks back.

Brushless Motor

As a professional carpenter and contractor, I am always in need of a good angle grinder. I have gone through many different ones in the past, but none have really stood out as being better than the others. That was until I tried using a brushless motor angle grinder. This type of angle grinder lasts longer and has more power than any other one that I have used in the past. In addition, the runtime is increased, making it the perfect tool for any job.

Why Use Variable Speed Angle Grinders?

An angle grinder is a handheld power tool that uses an abrasive disc to grind away material. There are two types of angle grinders: right-angle grinders and vertical grinders. Right-angle grinders have a 90° angle between the grinding wheel and the handle, while vertical grinders have a grinding wheel that is parallel to the ground. 

Variable speed angle grinders provide more control and flexibility than fixed speed angle grinders. With a variable speed grinder, you can tune the wheel’s speed to fit the task at hand. This is important because different materials require different speeds to be ground effectively. For instance, if you are grinding metal, you will need a higher speed than if you are grinding wood. 

Additionally, variable speed angle grinders allow you to use smaller wheels for greater precision.

What’s the Best Angle Grinder Size?

Are you in the market for a new angle grinder? If so, you may be wondering what size is right for you. The truth is, there is no one-size-fits-all answer to this question. It all depends on the project you’re working on.

That said, if your project requires a larger size, then a 4.5-inch angle grinder may not be big enough. In that case, you’ll need to go with a model that’s 5 or 6 inches in diameter.

On the other hand, if your project is small or medium-sized, then a 4.5-inch angle grinder should do the trick. These grinders are versatile and can be used for a variety of tasks, from grinding to cutting to polishing.

So which size is right for you?

What Can an Angle Grinder Cut Through?

An angle grinder can cut through many materials, depending on the blade that is attached. For instance, a diamond blade can cut through steel, tiles, and concrete. By attaching a grinding wheel, an angle grinder can be used to remove rust or polish metal. An angle grinder can also be used to sharpen blades or other tools.

Can My Angle Grinder be Used For Polishing?

An angle grinder is a versatile tool that can be used for a variety of tasks, including polishing. However, you need to select the right wheel for the job. A grinding wheel is great for removing material, while a polishing wheel will give your surface a smooth finish.


A good sharpener will help you sharpen various other tools and cutters.

In addition to the rhetorical cutting aid, the right variable speed angle grinder can also increase the cutting speed of rods, PVC, pipes, and cables.
