How to work with an angle grinder correctly

It is difficult to remember a tool that was used as widely as the grinder. If there is welding to be done, then be sure to take it with you. If manipulations with reinforcement are necessary, then here too this tool is the first assistant. The most important thing is not to forget that the device is hazardous, and safety precautions must be strictly observed. Mastering the operation of an angle grinder must begin by learning how to remove and install a disc. Then you should learn how to turn the tool on and off and remove the protector. Next, get acquainted with the features of working with different materials.

How to work with an angle grinder: observing safety precautions

An angle grinder should be considered one of the most dangerous tools, since it not only runs on electricity, but also does so at high speeds. Following the following safety rules will help reduce the likelihood of injury:

• use of protective equipment;
• checking the reliability of fixation of the protective casing;
• During operation, the grinder must be held tightly;
• absence of damage on cutting discs;
• the protective shield must separate the circle from the person;
• Before starting work, you should check the tool in idle mode;
• Before you begin, you must carefully inspect each of the nozzles;
• After finishing work, you should check the disk fixation;
• if the angle grinder has a rotation speed regulator, then its installation should be carried out in accordance with the recommendations of the instructions;
• cutting is carried out strictly at the recommended speed;
• To ensure that there is no dust during the working process, the cutting area must be moistened;
• breaks should be arranged;
• you can put the tool down only after a complete stop;
• when the disk jams, you need to stop;
• When manipulating wood, extreme care must be taken;
• It is worth keeping an eye on the cord so that it does not accidentally fall under the disk;
• Circular saw blades cannot be used, as they are designed for different operating speeds.

Basics of using an angle grinder

If you follow all safety requirements, then using an angle grinder is not so difficult, but you need to know the basic rules for using this tool.

Removing and installing the drive

In order to replace it, you need to press and hold the button that locks the spindle. After this, using a wrench, you need to unscrew the flange.

Now the disc can be removed. When installing a new one, all steps are performed in reverse order.

How to turn the tool on and off

Once the cutting disc is in place, the angle grinder can be used. On almost all models, the start button works in two positions:

1. When you press and hold it, the tool is activated. When it is released, the grinder stops.
   

2. The button is pressed and then locked in this position. If you let her go, the work will continue.

It is better to lock the button during grinding. Even if the tool breaks out, nothing dangerous will happen. When cutting work is carried out, the button does not need to be fixed. If something happens, it will be much easier to stop the angle grinder.

Removing the defender

A protective casing is a necessary thing, especially if you need to cut some part. However, during grinding it turns into a nuisance. In most angle grinders, to get rid of the casing, you only need to unscrew a few screws. The example considers an angle grinder with a different method of removing the protective element.

It is equipped with a special fastener, which must be pulled towards you, after which the casing rotates inside the groove.

How to properly use an angle grinder for different materials

An angle grinder can process various materials. But each of them requires special handling. Which one exactly? Let's try to figure this out.

How to work with wood

Oddly enough, but sometimes there is a need to cut not a metal part, but ordinary boards. For this case, there are special discs for grinders, “decorated” on the sides with teeth. They must be used carefully. You cannot use a circular saw, since they are not designed to work at speeds of more than three thousand revolutions.

The Bulgarian is much more resourceful. And the disk itself under it is made of steel, which is particularly fragile, so that it collapses at the first jamming.

How to work with ceramics

Cutting porcelain stoneware or regular tiles is only possible if you have a diamond-coated blade. It can be whole or divided into segments. Usually this cutting method is called dry. If you do not cool it with liquid during operation, then it is necessary to interrupt operation every minute and a half.Solid discs do a good job even with paving slabs.

Metal cutting

This is precisely why the grinder was invented. With its help you can saw not only reinforcement, but even rails. But when working with metal, you need to be extremely careful.

You should be especially careful with the cutting disc. You need to pay attention so that it does not get stuck in the cut. It is better to hold the workpiece so that the cut piece is in the air. All kinds of corners and rails should not be sawed in one pass, but each side should be cut separately.

If the workpiece is thick, then you should cut only in a straight line. But in order to make a figured slot, first of all, you need to make a straight cut in the form of a certain segment. Excess parts are removed. Strong pressure on the angle grinder should be avoided.

Working with glass

Before you start cutting glass with a grinder, you should study a little all the characteristics of this material. Despite all its transparency and fragility, it has good strength characteristics. Moreover, it is not just a durable material, but also hard and resistant to heat. Taking and cutting a bottle at home will not be very easy. Here, appropriate tools are required, and the conditions are suitable.

Glass can only be cut with a grinder. But it's done very quickly. The only thing you need to do this is to install a diamond-coated disc for concrete or granite on the grinder. During operation, the cut area must be continuously watered with water. Since glass is a fairly durable material, a lot of heat will be generated when cutting. It negatively affects both the disc itself and the edges of the cut. Water allows you to make the cut line more even, and the diamond coating will last for a long time.
