Buyer Guide to Choose a Grinder

You will find a large variety of grinders on the market. There are large ones, perfect for demanding and professional jobs, and in a mini version, which are the favourite of DIY enthusiasts thanks to the many features.

For you to understand what grinders are, we have prepared this complete guide to purchasing the perfect grinder.

What Is a Grinder?

The grinder is an electric hand tool (although there are bench models). It is made up of a high-power electric motor connected via reduction gears (if it is an angle grinder) or directly to the motor axis (in the case of straight ones). The disc attaches to the tip of the axle.

The disks are used to determine the activity, given that depending on the chosen disk, we can carry out a particular type of work.

These are very efficient tools, with little energy consumption that will allow you to carry out a large number of tasks, from cutting to filing or cleaning a surface, always using a suitable disc.

What Are the Grinders For?

This is undoubtedly an essential point because defining what a grinder is for will allow you to know what you can use it in your laboratory or at home.

The grinder can be used for a large amount of professional or domestic work, and thanks to the possibility of changing the disc, it offers enormous versatility.

You can cut marble, ceramic, or plasterboard. Generally, you will be able to perform cutting, cleaning, and sanding. Depending on the size of the grinders, you can perform one or the other task.

For example, for demanding jobs, you will need a large model with a powerful engine, while for small DIY jobs, you will need a little or mini.

What Are the Differences Between a Grinder and A Mini Grinder?

There are different types of grinders depending on their size, power, and diameter of the discs. They are distinguished in grinders and mini grinders.

The most common drives for the mini format are those of 115, and 125 mm, and the power of its motors generally ranges from 500 to 800 W.

Instead, the most common discs for traditional grinders are 230 mm. These tools, as we have already explained to you, are designed for very demanding professional jobs.

Its motors offer much higher power between 2000 and 2600 W. Therefore; they are highly appreciated by professionals.

How and When Do I Have to Change the Grinder Disc?

The grinder disc must be changed when it shows signs of wear due to use. You will also need to replace it if damaged.

Changing the drive is easy, just turn off the machine and place the included key so that the grooves coincide with the holes in the central disc. Then, press the indicated key to lock the axis.

Once the clamping and cutting disc has been loosened, remove it altogether, and insert the new CD. You will have to position it so that the central hole coincides with the axis.

There must be no free space. Place the clamping discover the cutting disc, and proceed to unlock the axis. Use the wrench and turn counterclockwise to tighten.

Below, we explain how to change the disc of your grinder step by step:

  1. First of all, check the wear of the disc. If it has imperfections, grooves, or has shrunk due to use, it must be changed.
  2. To change the disc, you must first disconnect the grinder from the power. If it runs on batteries, turn it off.
  3. Use the locking mechanism, together with the key to loosen the clamping disc.
  4. Remove the clamping disc altogether.
  5. Remove the used disc.
  6. Place the new disc on the axle.
  7. Place the clamping disc back in place. Check that it is well fitted without free spaces.
  8. Tighten the disc by turning the key counterclockwise.
  9. Check that the disc is fully secured in its space.

Is It Possible to Use the Grinder for Sanding? Like?

Grinders are very versatile tools, as they support a large number of discs, including those for sanding.

In these cases, you will need to have a rubber accessory that serves as the basis for these particular smoothing discs to ensure their durability. The sandpaper has different thicknesses and consistencies.

Before you start sanding, you have to fix the piece you want to work with with a vice or another type of tool, so that you can hold the grinder with both hands. You don’t need to exert pressure, just place the machine on the workpiece and move it slowly from one side to the other, leaving the disc to work. You must wear the necessary protections.

Grinder or Hacksaw?

Depending on the work you need to do, you can choose a grinder or a hacksaw, since they are different tools with different functions. The hacksaw differs because the movement of the blade goes from top to bottom. Therefore the tool must be perpendicular to the work surface.

The grinder works instead with the rotation of a disc, in this case by cutting, at high speed. It is essential to take the power of both the hacksaw and the grinder into consideration when choosing between the two to do the job. In the case of hacksaws, some models include dust extractors in the cutting nozzle.

What Accessories Should a Grinder Have?

As we explained earlier, grinders can accomplish a wide variety of tasks when used with the correct discs. Besides, these tools usually have a large number of accessories that make them very useful and easy to use.

Here are some of the essentials:

  • The cutting discs. Without the discs, the grinder will not work. The cutting and parting discs are used to cut all types of material, from metals to ceramic, marble, or wood.
  • Pipe cleaners and brushes. These accessories are used to clean and polish metal surfaces.
  • Metal brushes. Disc-shaped, they are used for stripping metal or wood surfaces. They should be used with great caution, as they could damage the surface.
  • Sandpaper discs. Suitable for light sanding. They are generally used for the preparation and finishing of surfaces such as concrete walls.

What Are the Risks of Working with A Grinder?

The use of grinders has grown a lot with industrial development and thanks to their high effectiveness. Technically, they are portable electronic machines used for cutting and sanding.

If you don’t pay attention to some basic principles of use, you could be the victim of more or less severe accidents.

To help you use your grinder, we have developed the following guide, which illustrates some of the main risks:

  • Risk of blows when unequal machining parts.
  • If you do not have the proper equipment, you risk inhaling toxic dust produced during cutting.
  • Incorrect body posture while cutting can cause muscle damage or accidents.
  • I hear damage due to the noise produced by the machine during cutting.

  • Exceed the maximum revolutions of the appliance.
