Which Side Is Putting A Disc On An Angle Grinder
What are the discs for angle grinder? Which circle to cut?
Choosing a disk for an angle grinder (angle grinder), first of all, you must adhere to the diameter set for a particular model.
In the article we will talk about:
And this is really a very important point, because often, in order to increase the depth of cut or the surface area to be treated, some “craftsmen” remove the protective cover and establish a circle of superior dimensions.
Firstly, because of this, the tool itself fails much faster (the gearbox breaks), and secondly, quite serious injuries occur. The fact is that each disk for an angle grinder has restrictions on maximum revolutions or, in other words, on rotation speed.
The wider the diameter of the circle, the faster the revolutions should be. That is why large disks at high speeds very often simply rupture, and given the fact that there is no protective casing, the consequences can be most dire.
What are the discs for angle grinder in diameter
In total there are 5 main modifications:
The most popular are the angle grinder, and, accordingly, discs ∅ 125 and 230 mm. In everyday life, small models are most often used, while in professional work a more powerful and productive tool is used.
How to choose a disk for an angle grinder for working with various materials
The versatility of an angle grinder lies in the fact that it can not only cut almost any materials, but also grind all kinds of surfaces or sharpen a tool. The main thing is to choose the right drive. So what kind of discs are there for an angle grinder? The main groups are as follows:
- Cleaning (grinding)
- Grinding (peeling)
In turn, in each group there are several varieties. Cutting discs are abrasive, diamond and wood. The former, as a rule, are designed for cutting metal, although there are abrasive wheels on concrete.
They differ in the components used in the production, and the buyer can distinguish them by color on the information sticker (for metal. Blue, for concrete. Green), by the inscription (metal. Steel, concrete. Concrete) or a schematic representation of a particular material.
Diamond cutting wheels are designed exclusively for stone, concrete or ceramic products. The most common question that arises among home masters is which disc to cut a tile angle grinder with. In general, circles with continuous spraying without segmentation, grooves and slots are recommended for these purposes, since they leave a minimum of chips on the enamel.
However, they are used in conjunction with water cooling, that is, on special electric tile cutters with a continuous supply of water. For domestic purposes, you can use segmented disks, which are also suitable for red and silicate bricks, pavers, concrete, paving slabs, etc. It is not recommended to work continuously with any diamond wheels for more than 2 minutes, because, despite the cooling grooves, cuts and grooves around the entire circumference, they dry very quickly when dry cut.
Another common question, how to cut a thick rubber or car tire? An angle grinder can also perform this operation, for example, with a diamond blade. But you need to do this in the open air, since when heated, rubber emits a pungent smell and can even smoke.
You need to be very careful in the case of tires, as in the middle of the ramp there is a metal court. Its diamond, of course, will cut it, but at the same time small particles of metal can bounce off. In addition, rubber very often clamps the disc, so you need to unclench the edges during the cutting process.
For cutting wood, there are special saw blades. This is the most dangerous type of circle, because even with the slightest contact with hands or fingers, they leave serious injuries. They are recommended to be used only under condition of stationary mounting of an angle grinder to a workbench.
If this is not possible, you need to work as carefully as possible, in no case do not remove the protective cover, do not press on the tool, do not make any sudden movements, be sure to wear a mask and tightly fitting fingers of the signet. It is better to choose disks for an angular grinder for a tree with a small tooth, since such circles are less likely to provoke a back strike effect.
What are grinding and grinding wheels for angle grinder?
There are two types of grinding abrasive discs: flat and cup-shaped. In the first case, circles practically do not differ from edged analogues. The difference lies only in their thickness, which is at least 5 mm or more.
Cup-shaped varieties are more convenient to use, as they allow you to cover more of the treated surface in one pass. Use such disks for an angle grinder in order to clean the welds or sharpen the cutting tool.
There are four types of grinding or grinding wheels:
- Petal (emery) disks for an angle grinder are mainly used when removing old paint or varnish, polishing wooden surfaces.
- In order to clean the surface from persistent contamination or rust, special wire nozzles are used.
- For polishing the stone, diamond bowl-shaped modifications are intended.
- For polishing metal, dish-shaped nozzles made of rubber or plastic are ideally suited to which a removable emery pad or abrasive mesh is attached.
Which side to put the disc on the angle grinder?
This question is easiest to answer. A flat circle is marked outward. Cup-shaped modifications can only be set in a single position, so an error is excluded here.
By the way, professionals say that it makes no difference which side to put the disc on the angle grinder. Their conviction is based on the fact that in circles, even professional ones, there is no arrow pointer in which direction the rotation should take place. Therefore, the installation can be carried out by either side.
