Cutting sheet metal using different instruments only at first glance it might seem a simple matter. Indeed, depending on its thickness and size must be used various ways. It is understood that the sheet thicknesses can be cut with the help of gas, but in this case perfectly straight edge will not require additional processing, which is an extra waste of time. How, then, to do? Today we consider the 3 easiest ways to cut sheet metal grinder so that the edges are smooth and do not get injured.

Safety when working with an angle grinder
This question is the most important. After all, with violation of rules of operation of the Bulgarian you can get a serious, sometimes incompatible with life traumas. Consider the main ones, are required to comply.
- disk size. Many people believe that if you put a large disk on a small grinder, removing the protective cover, nothing terrible will happen. Say, much more powerful angle grinders. This misconception is dangerous to life. The fact that a small Bulgarian turnover is much higher, and therefore require different drives for them. When large disk installation wizard, most likely will not even have time to start work - the drive will scatter when you turn that in the absence of guard will lead to disastrous results.
- sense of rotation. Some "masters" do not like the fact that when working under the feet of the sparks fly. They unfold casing rearrange the handle and start the work. That is what often leads to the fact that the disc shatters at the toe of the sharp edge. The rotation of the disk when using angle grinders must be made "on" and not vice versa.
- Personal protective equipment. Wear protective goggles or visor, wear gloves, mask or respirator is necessary. This will protect from burns, eye injuries, which, unfortunately, such work is not uncommon.
Normal cut thin sheet metal
The metal thickness of 1 mm cut is not too difficult, but here it is necessary to be extremely careful and accurate. It is the cutting of the disk material is often "snack". First of all, you need to make sure that the cutting plane of the circle there are no defects. They lead to the fact that the cutting disc shatters.
Should start from the distal edge of the sheet, moving back. In this case, it turns out that the master pulls the grinder. The disk does not have to dive deep - a maximum of 5-6 mm. With this method of cutting it turns out that the cut-off wheel or just can not catch hold. If the drive will go deep, the contact area is sharply reduced to the metal. This results in the hooks as a result of which the cutting disc may scatter.
How to cut a thicker sheet of metal by means of grinders
Consider the case of a sharp sheet metal thickness of 8 mm. Here it is best to move forward - so much more convenient. However, if you take just a seam on the traced line will receive flaws - perfectly smooth it does not do. In this case, the voltage at the hands increases - it has to constantly ensure that the Bulgarian is not left aside. In order to avoid this, there is a very good way.
At the place of cutting stacked steel bracket, which is pressed against the sheet clamps on both sides. Line drawn in this case must be with its vertical portion. Now it is possible to pass several times along it, a bit touching the corner so as to obtain a groove depth of about 1-2 mm. You can then remove the area and usually begins cutting. That groove does not give the drive away with the planned trajectory, and the edge will turn out perfectly flat.
Working with a small grinder even more dangerous than a large

It can be done differently. Initially, it performed the same work as that of the previous version - is drawn strip is placed and pressed area. But here is a little deeper groove - 45 mm. After the area is removed, a metal residue can simply dolmans and handle region by means of angle grinders with grinding disc. However, there may be small pits on the edge, which makes the second option is more acceptable.
Summing up
The fact that the Bulgarian is very suitable for cutting metal, not disputed. However, it must be able to work and to keep it strictly all safety precautions and safety regulations. You have to understand that they were created precisely in order to preserve the life and health of the master, working with such a dangerous tool as angle grinder.
