To successfully carry out your DIY projects, there is nothing better than using an angle grinder. Due to its versatility, this tool allows you to perform a wide range of tasks. As it is wildly popular on the market, it comes in many models that meet all expectations. If you want to find the right product, we invite you to read this article summarizing the important points to know about it.

What is an angle grinder?

You have probably heard of it, but you might not really know what it is. The angle grinder or angular grinder is an electric tool mainly used to grind or cut materials. For the latter role, it is not really necessary for straight cuts, but rather for operations requiring curves.

Compared to other types of grinders, it is equipped with a rotating disc, but with a remarkable specificity. With this product, it is the axis of rotation that creates the right angle. Thanks to this positioned axis, it demonstrates great versatility.

You can use it for a wide range of tasks such as polishing, sanding, cutting, and of course grinding. Thanks to its interchangeable disc, you just need to replace it with other accessories and use it according to your needs.

Different types of discs and angle grinders

There are several types of discs and you can choose depending on the activity you plan to do. First, there are grinding wheels useful for deburring a large cut, hard discs for cutting, semi-rigid discs for sanding disproportionate materials, diamond cutting discs, and finally, laminated or brushed ones. This last category is essential during polishing.

As for angle grinders or disc grinders, the grinder stock on the market offers you a choice between 2 types. They differ by their power and disc diameter. The one-handed grinder is not only lightweight but also small in size. Its disc diameter ranges from 115 mm to 125 mm. The two-handed grinder, on the other hand, is the larger model with a disc from 150 mm to 230 mm.

Regarding the power system, the corded angle grinder is a very common product that plugs into the mains. On the other hand, the cordless grinder operates on battery. Pneumatic models that connect to a compressor are also available.

If you are working on delicate materials such as glass walls, the use of a grinder is prohibited and it is better to know how to cut tempered glass with the appropriate tools. For your carpentry projects requiring brute force, a reciprocating saw will ideally complement your portable power tool collection during demolitions. Finally, for finer finishing on flat surfaces, using an orbital sander remains the most effective solution after an initial rough grinding with the grinder.

What is the best angle grinder?

Here are some important criteria to consider to help you find the ideal product:

Power

Power determines the product’s performance. If you want to equip yourself with a competitive tool, it must have a powerful motor. This parameter defines the grinder’s ability to sand, cut, deburr, or polish materials quickly.

For occasional use, an angle grinder with more than 600 W will suffice. If you use it regularly on construction sites, a product with power over 2000 W is capable.

For those who have a cordless angle grinder, its capability varies according to the battery power. The higher it is, the more qualified the device.

The disc

To use the angle grinder, you must insert discs into the housing. They come in many diameters and materials. You choose based on the type of use you plan.

For angle grinders with discs of 11.5 or 12.5 cm, their common feature is their small size. As such, they can be extremely easy to handle. If you are looking for the best angle grinder for small DIY jobs, this category is an interesting alternative.

As for the angle grinder stock equipped with a large diameter, i.e., 23 cm, the machine is heavy. It is mainly intended for professionals, as it can be very effective. It helps you cut hard materials like concrete floors.

For your information, the disc diameter must be proportional to the device’s power. These two criteria influence energy consumption. The wider the disc, the more current it uses, as its cutting depth is greater.

Comfort of use

If the tool is intended for regular use, the best angle grinder must be comfortable to handle. To identify it, make sure that the product’s handle is ergonomic, providing excellent grip. If you want to use the grinder with two hands, opt for an item equipped with an additional handle.

Still from this perspective, favor a lightweight model, because otherwise its handling quickly tires your arms. However, it should be noted that powerful grinders often appear bulky. If you are therefore looking for a powerful product, you must expect it to be heavy.

The level of safety

High-end grinders sometimes feature an electronic cooling option. It prevents the risk of motor overheating. For those who know from the start that the machine will be used for long periods, an item equipped with overload protection is essential.

What is the difference between an angle grinder and a cut-off tool?

Many buyers ask this question before purchasing. If you are one of them, know that there is not a big difference between them, since it is the same device. Manufacturers call it an angle grinder cut-off tool.

However, it must be said that there is still a reason explaining these two names. It is mainly the accessories to be used that justify the change in designation.

We speak of angle grinder when using the flat part of the disc. On the other hand, DIYers refer to the cut-off tool when they use its cutting element. Also called a disc chainsaw, it has the same characteristics as an angle grinder, but is distinguished by its cutting power.

If you wonder what these tools are used for, know that their difference also lies in their use. The angle grinder is a valuable aid in sanding a surface. It also helps remove rust from iron. By equipping the tool with brush accessories, it allows you to perform a less powerful and lighter activity, adaptable to fragile parts. The grinder is used with many materials such as glass, steel, and concrete.

The cut-off tool, for its part, is widely used in the construction sector. With the integrated fine diamond disc, it is perfect for cutting wood and cutting tiles. Some call it a grinder chainsaw, since it allows grinding and cutting at the same time.

How to use an angle grinder?

Whether it is a corded angle grinder or battery angle grinder, this electric tool is used with caution. It can be powerful with its high speed around 10,000 revolutions per minute. For this reason, it is advised to wear protective glasses to protect yourself from sparks during its use.

No matter the model or delivery, this device generates a lot of noise during operation. Your hearing might not tolerate prolonged use. In this sense, it is preferable to wear hearing protection to avoid irreparable damage. Just like working on a construction site, reinforced gloves and safety shoes are essential. With certain materials, you also need a dust mask for the health of your respiratory system.

Once all these measures are taken, you can start your DIY project. Whether it is grinding, shaping, cutting, sharpening, deburring, or rust removal, it is highly recommended not to apply too much pressure to the angle grinder. You can simply let its speed do all the work. If you force the disc when cutting metal, it may break and you could injure yourself. During polishing, if you push it down excessively, you will likely leave marks on the piece.

Whether you plan to do cutting or grinding, the trick is to choose the right disc. If your angle grinder is struggling, know that you are working with the wrong disc in this case. You should therefore change it immediately.

For its replacement, make sure to unplug the tool. Then, firmly attach the new disc. Hold the handle of the device and orient its protective guard according to the piece to be worked on. If your project involves cutting the material, always start from the top to limit the risk of kickback. However, if you plan to grind metal supports, you should work with an angle of 20 ° between the disc and the element to be worked on.

After the operation, avoid handling the product, as the cut material and the disc are still hot. It is better to place them in a suitable place to cool before handling them again.

It is therefore appropriate to get rid of it to avoid clogging. To achieve this, it is imperative to disassemble the device and remove the residues after each use.

To do this, simply remove the dust that settles on the circuits. First, open the casing of the grinder with a screwdriver.
