Buying Guide – What is the best angle grinder on the market?
The angle grinder is a versatile tool that makes all kinds of cutting, sanding or grinding work on any type of material easier. To equip yourself properly, follow the advice in our guide to buying the best angle grinder, with which you will find quality models that give that touch you are looking for in all your DIY jobs.
When choosing an angle grinder, the operating power is one of the elements that we must take into account to avoid falling short when doing any job. A power that, as we will see when talking about the disc, it is necessary to adapt to the tasks that we are going to carry out, so that the product has enough capacity to carry out the same efficiently.
If we take a look at any comparison of angle grinders on the market, we can see how the power is usually around 700 watts approximately, within the general models with a 115-millimeter disc. This power is enough to generate a rotation level of about 11,000 revolutions per minute, with which to move the disc properly and obtain adequate performance when working. However, as with power, this speed has small variations in terms of the maximum idle speed that can be achieved with the product.
It is convenient that this speed can be easily adjusted, since not all materials or tasks require the same power. If we are talking about more fragile materials or more precise work, it is important that the speed is adjusted downwards, to avoid their deterioration during the work. That is why it is convenient to assess the speed control system, which should have the greatest possible versatility.
If the operating power of the product is important, so is the disk that is moved by the motor. Depending on the type of work you are going to do, you will have to use another disc, also having different sizes and thicknesses, which are also adjusted to these jobs. You should know that if the grinder mounts a large disc, you can mount smaller discs, but not the other way around.
Specifically, the most common grinders are usually 115mm in diameter, being practical and light for carrying out small jobs. Discs that are effective in cutting and roughing material, although their cutting capacity is between 20 and 30 mm, which means that they lose efficiency with thick materials. In this case, we can bet on models with 230mm discs. These discs allow you to work with thicker materials and be more efficient when working on large materials.
In addition to the above, it is also necessary to assess the way in which the discs are changed. A task that must be simple, so that it is not necessary to pull many tools or spend too much time in the change process. A fundamental issue to avoid inconveniences during the process and also maintain proper safety in the work process, which must even be above how much the grinder costs.
comfort and safety
To finish our tips for finding a good and cheap angle grinder, we will review both the comfort of use of the product, and the safety it offers us when working. Two fundamental elements in any power tool, but even more so when it comes to cutting and sanding tools like the ones we are discussing.
On the comfort side, it is worth taking a look at the handles or fastening elements of the product. In general, these models have a main support handle together with a secondary handle, which allows the position of the cutting area to be maintained and helps to better control the process. If, in addition, the product has improvements such as a vibration reduction system or similar, everything is easier to use.
As for the safety of the product, it is key that the product includes a protection shield that prevents possible sanding or cutting debris from jumping in our faces. In this security there must also be a mechanism that stops the operation of the disk automatically in case of problems, to avoid risk when working due to an operation of the disk without complications.
