Buying Guide -Best Angle Grinder Wheel For Cutting Metal
Among the power tools we have at our disposal, the grinder is one of the most versatile. This serves to make cuts, polish, sand or rough materials, among other options. But for the product to perform as it should, it should be clear what we should look for before buying. Some aspects that we summarize in this guide to buy the best angle grinder wheel for cutting metal, where we give you all the clues you need to make buying a good and economical grinder much easier.
The first aspect to determine is the type of grinder that we need or that require the tasks that we are going to execute. This is something that is easily understood just by taking a look at any comparison of grinders, in which we will find different types and models with which to perform different tasks.
Starting with conventional grinders, it will be necessary to choose their size. In general, we can say that there are large grinders, for discs of 12.5 cm or larger. We also have medium-sized ones, with 11.5 discs about 7.5 centimeters in diameter. And finally, we would have the mini grinders, ranging from those with 7.5 cm discs to the smallest ones, common in marquetry work or crafts. These distinctions are approximate, given that the variety of products on the market is more than considerable.
Regarding the type of grinder, apart from the conventional ones, we have others such as straight grinders. These are more useful when making cuts because they allow you to see everything clearer. We also have table grinders, which we do not have to carry in our hand, but instead are placed on any support and have rotating wheels with which to polish. They are alternative models to conventional and suitable for certain jobs.
Power and power
Within the parameters that mark both how much it costs and what a grinder is for, its power is also found. This power is given by that offered by the engine, although the speed of rotation it reaches must also be verified. The higher these two parameters, the greater the ability of the product to work efficiently, especially on harder materials.
As a reference, a conventional grinder can start at around 500 watts of power, if it works in plugged mode, while a mini grinder is usually around 100 or 150 watts. As for the speeds of rotation, conventional models are around 10,000 rpm, while smaller ones can increase the level to almost 20,000, since they use smaller discs and, therefore, spin at a higher speed.
This leaves us the issue of food, which we have already raised. Conventional grinders are usually wired, so we need a plug nearby to use them. Battery models, meanwhile, do not require a plug but carry a battery from which they obtain power. This is something that gives more comfort to the use, although it is also true that plugged grinders are cheaper than conventional ones. So it’s all a matter of seeing what suits you.
Comfort of use
Although there would be several aspects to comment, perhaps the convenience of use is the most interesting, as in any manual tool worth its salt. Something that we must take care of even in an economic grinder, since if it is an uncomfortable use, surely it is not pleasant to work with it.
For a grinder to be comfortable, you need to have a good grip. This grip affects both the body of the machine and the additional handle, which is almost essential today. This is something that must be combined with a light or tight weight, so that we do not have to carry too much during work. And if the product has a compact size, which facilitates its movement and reach where necessary, much better.
On the other hand, comfort also affects disk change. Therefore, the system included in the grinder for such a change must always be comfortable and easy to execute. Models that allow the change without tools are preferable, although if this process is not complex, nothing happens to use a key. By the way, do not forget to also check the safety zone, which prevents the projection of particles. It is something that will give you extra comfort during work.
Frequently asked questions
Q1: How to use a grinder?
The use of the grinder is something that depends on what we want to do. If what we want is to perform cutting tasks, we should be done with a suitable support on which to mount the grinder and hold the piece. When sanding surfaces, we will have to run the grinder through the area to be sanded, removing burrs and other unwanted elements from the surface of the object to be sanded. Something similar happens if we want to sharpen any cutting element, whose process is quite similar to sharpening.
Q2: How to sharpen an ax with grinder?
In order to sharpen an ax with a grinder, it will be necessary to previously check the grip of the cutting head on the handle, as well as clean the cutting blade, sanding it if necessary to remove rust and dirt. Next, the ax blade is placed on a suitable support and we proceed to apply the grinder disk on the surface of the blade, trying to give it an angle of 5 to 15 degrees. It is important to keep the original edge and not overheat the blade during the process. Once the sharpening is finished, we let the blade cool for 10 minutes and we will apply some protector to it, if we consider it necessary.
Q3: What is an angle grinder?
The angle grinder is nothing more than a conventional grinder, although with its full name. In fact, almost all grinders are angular, since they can work at different angles depending on the tasks we have to perform. Even straight or edge grinders can also be angular, since the fasteners allow this working angle to be adjusted.
Q4: How to change the coals to a grinder?
Coals, also called brushes, are fundamental elements for a grinder to work. These tend to deteriorate with use, although luckily their change is relatively simple. We will start by opening the product housing, always verifying that the grinder is unplugged. In general, it is usually enough to remove the screw from the lower cover of the grinder, located in the cable area. Once the housing is open, we will have to look for the carbon holders and remove them, lifting the tab that holds them. Here we place the new coals, verifying that they are well placed and connected. Finally, we test the grinder and, if everything is correct, we can close the housing.
Q5: How to cut glass with grinder?
To make this type of cuts, we must use a specific disc for this material, which generally has a diamond edge. To proceed, we must place the glass properly on a support, mark said area and proceed to the cut very carefully, without exceeding the speed or pressure on the edge to be cut. It is important to remember that this cutting process is not suitable for all types of crystals, especially if they are thick, so it should be limited to thin crystals and appropriate to the size of the disc
