USAGE GUIDE: HOW TO USE A GRINDER

When working with tools, it is necessary to take into account a series of considerations and precautions that guarantee optimal use and safe execution . Today we are going to dedicate this post to explain how to use a grinder , a very useful power tool due to its versatility of use.

WHAT IS A GRINDER?

Grinders (also known as radial grinders) are power tools that work with a small motor that rotates a disk at high revolutions. They usually include an adjustable knob or handle on the side to facilitate grip and manipulation. They are used to cut , sand and polish various materials .

With the grinders, very good results are achieved, since the finish of the cuts is clean and straight . The jobs that can be performed range from DIY tasks to professional level jobs.

We are going to review below its possibilities of use and the materials and surfaces on which it can be worked.

USE AND SURFACES OF USE
Depending on the complexity of the work, it will be necessary to purchase a grinder or a mini-grinder , ideal for domestic work and available in a cordless tool version, which provides total freedom of movement.

There is also a wide range of grinders with various power motors . Before making your purchase, think about the jobs for which you are going to use it and consult with your supplier, who will always know how to guide you according to your use needs.

As for spare parts, there is a very diverse repertoire of discs with different diameters . The choice of one type of disc or another will depend on the material on which you are going to apply the grinder, since each one requires a specific disc, and will allow different uses of cutting, sanding, parting or roughing in almost all types of materials. The most common are stone, ceramic, brick, ceramic and granite.

 


 

INITIAL PRECAUTIONS
Before you start working with grinders, remember that they are powerful cutting power tools and that, therefore, it will be necessary to take extreme precautions with respect to a manual tool.

The grinder should not be handled with fear, but it is necessary to observe some basic safety instructions .

Protective equipment
First of all, protect your hands and eyes . The cutting discs on the grinder are very sharp and when they come into contact with surfaces such as iron or metal, they will tend to spark. Therefore, it is essential to properly equip yourself with work gloves, goggles and a mask.

Accessories
Once the protective equipment is in place, it is advisable to prepare the work area . Review and prepare the accessories that you will need to check that they are in good condition. In addition, having them at hand will not only make your work easier, but it will also prevent you from having to move or move a lot and, thus, possible accidents are reduced.

Remember also that you must use the accessories that correspond to this tool . Although grinders are similar to drills, it is totally inadvisable to use the accessories of one for the other. Follow the manufacturer's instructions and choose the appropriate discs for each material accordingly. Also try to check that they are not too damaged.

Other security considerations
It is important to remember that the grinder produces sparks, so work with it away from combustible materials to avoid possible fires.

Get used to the weight and ergonomics of the tool before you get to work with it. Take a few practice runs or start with simple jobs before moving on to more complex tasks.

Finally, if you work with cordless grinders, you can forget about the cables but, if not, try to keep the cable away from the disk while it is running.

 

TOOL EXECUTION
Execution with the grinder, as mentioned before, does not have to be dangerous. When working with it, always keep in mind that you must hold it firmly and that you must avoid placing yourself in forced postures, places that are difficult to access or surfaces that may make balance difficult.

Well, with that said, let's now look at the uses of the grinder in more detail :

Material roughing
It consists of removing material superficially. It involves making horizontal micro-cuts to remove part or all of the material. There are specific discs for roughing, but a similar function can be achieved by applying thin discs and placing the machine with a slight incline on the material.

Ceramic cutting
With this power tool you can make cuts in materials made of ceramic, such as tiles.

Rust and paint removal
If instead of using a cutting disc the replacement is replaced by a special brush, you can completely remove layers of oxide on metal surfaces and deteriorated paint.

Slashing
Grinders allow you to draw straight lines in brick walls, which can later be embedded in an electrical wiring installation.

Work on iron
Enclosure work can be done by cutting bars, beams and sheets to, for example, build gates or garage doors.

Leaky
Among the varied repertoire of accessories for grinders, there are crown-shaped pieces to achieve perfect circumferences in metal, iron or wood.

 

THINGS TO CONSIDER AFTER USING THE GRINDER
When you've finished working with the tool, the first thing to do is wait for the disc or brush to stop spinning . Next, place the machine on a level surface and, if you have finished working with it, do not forget to disconnect it from the electrical current.

Also try to clean the vents . In this way, you can prevent the engine from overheating and breaking down.

 

Final tips
And finally, a few tips to optimize the use of the grinder :

• If you are going to cut a bar, look for very stable supports and leave enough height between the bar and the support table. To prevent the pieces from falling and closing towards the disc, which could cause it to split, it is advisable to put the part of the bar on which you want to practice the cut in ruffles. In this way, the piece will fall out on its own and the cut will tend to open.
• Always bear in mind that you should not exert more pressure than necessary , since this forces the machine and, despite what it may seem, you will not be able to increase performance. Get the job done continuously, with constant pressure on the grinder.
• In the case that you are going to place a new disc , let it spin in a vacuum for about a minute and with the protector on.
• Well, with this article we hope to have solved doubts about how to use a grinder . Before launching to acquire one, inform yourself well or consult your supplier for advice on which one to buy from among thegrinder catalogthat you have available. Let yourself be advised only by official distributors and you will get the best power tools and optimal results !
