What should you consider before buying a grinder?
When working with a professional grinder, it is necessary to have a grip and support solid enough to prevent hands from slipping or accidents. These devices must have economic handles that fit perfectly in hand and provide secure handling while operating continuously with this device. A comfortable and firm grip defines first-class ergonomics, generating better performance and less exhaustion.
The amount of revolutions per minute, the power and the cutting speed during the turns, defines a practical grinder to perform specific work. Knowing the voltage used by this device will be of great advantage when selecting the model that fits your needs perfectly. They can vary in power, so, by finding the measurement in W or Watts, you can determine if this device can handle the tasks for which you have thought to do with one of them.
It is essential to take into account the type of disc you use since this is decisive when choosing the precise model for a particular task. The diameter of the discs may vary depending on the model and type of grinder, so taking this characteristic into account and verifying the diameter and type of drive to be used will guarantee you a better experience when making a replacement. During constant use, the discs may suffer wear on edge, which will force you to replace them.
Before buying the wrong grinder, you should verify that the weight is manageable for you, since, when using the device, you will need to have excellent support and ergonomics when holding it in your hands. Depending on the type of grinder, using excess weight devices could lead to more exhaustion and decrease the quality of performance when performing physical exertion. The easy-to-handle mills ensure better maneuverability when using them.
Both the measurements of the disc and its grip and body are decisive when handling a high-performance device like this. They usually have a standard size that allows proper handling and ergonomics, but, having multiple models for different purposes, you need to verify that the measurements are correct and that they adapt to your texture and weight. This will allow you to manipulate the grinder effectively, avoiding mishaps or injuries.

Advantages of using a radial
This multifunctional equipment offers its buyer a wide variety of benefits in his work, as well as different interests in the various activities he decides to perform, and then we will name each one of them:
- They provide excellent comfort: they are usually compact and low weight, which means they do not take up much space and are quite manageable.

Types of machines for grinding
There are several types of grinders, which are used in different activities depending on three fundamental characteristics: power, size, and diameter of the discs. Next, we will name them:
- Portable grinder: this type of mill is the most common on the market and the easiest to find. If you are an experienced professional or amateur, this is the most recommended grinder for you. It is mainly used to polish large surfaces, as well as to cut large pieces since they use large discs, more substantial than 20 centimeters in diameter.
- Mini grinder: if your passion is DIY, you like performing tasks and small jobs at home, but you don’t have much experience, we recommend this type of grinders. These are smaller than the previous ones and much easier to maneuver. Its diameter of 12 or 13 centimeters works perfectly to work with pieces of reduced dimensions, so they are excellent for jobs that demand precision, such as stripping metals or wood, polishing, cutting ceramics, among others. However, if you have to cut a sturdy material or work on larger surfaces, this mini grinder will not suffice.
- Desktop grinder: if you have a professional workshop or work with heavy and thick materials, this grinder will be handy. Their grinding wheels are more abundant than those of typical grinders, so they are used to polish, devastate or shape different materials, as well as cut others such as wood. It has the main feature and is that it is designed to remain fixed in one place, being heavy and not very portable machines. Unlike the radial grinders in which we move the device, and the piece remains fixed, in this case, we exert the force with the object that we are handling.
- Radial type grinder: these machines are usually used for cutting, polishing, or sanding. They are very versatile because by merely changing the disc and the angle at which it is used, we can perform different jobs. They are also quite comfortable since there are currently small models that barely take up space. Another feature that can encourage you to buy it is the option of some models that include discs that you can exchange with ease, allowing us to perform a variety of tasks with little effort and without investing large sums of money.
- Angle grinder: these grinders resemble radial ones. Some experts do not even make distinctions between them. The difference between the two is in the position of the disk: while the radials have it on the sides, the angle is directed downwards. These devices are perfect if you want to make angular cuts in parallel to the line of the material because they integrate a grip that will help you control the movements. Although they are initially used to polish metal, they can be used for other activities such as removing rust and paint, cutting ceramics, among others. In fact, there are versatile models that come equipped with wire brushes, abrasive stones, and other materials that can work for you in a wide variety of activities.
- Straight grinder: it is a kind of combination between the radials and the desktop or wheel. Generally, they are smaller than the radial ones. It is characterized in that the position of the disc is not horizontal, like the radial ones, but is parallel to the axis, although unlike the wheels, these are portable and not fixed. The discs of these grinders are small, which makes it the ideal tool if you work with small objects such as jewelry and watches and need particular precision. For the perfect use of this instrument, the quality of work will have a lot to do with the pulse of the driver.
How much should I fanciest in my grinder?
A grinder is usually a handy tool when it comes to heavy work. However, it is necessary to know how to choose the model and invest correctly:
- Cheaper grinders (less than $ 50): these teams can get to make cuts and roughing quickly, even so, it could be limited with some materials for the quality of its manufacture, so it is necessary to reconsider the investment in a product that is possible of a short term.
- Grinders of better quality (more € 50): selecting tools of a higher quality and range is the most beneficial for buyers since the investment will be an intelligent acquisition as far as the product is concerned, being durable and performing its function correctly.
Precautions while using a grinder
It is essential to know that you must not work the piece abruptly, always do it carefully, without losing firmness, you must work continuously, generating correctly on the machine, as well as, you must try to maintain a speed that fits the material you are using. Upon completion, wait for the disc to stop rotating to support it in a place with adequate leveling in order to leave it ready for storage.
Maintenance and cleaning of a grinding machine
This is a point where you must be very attentive so that no foreign body or material enters by mistake inside the grinder, and this is why you can clean your blender with a small brush to remove excess dust or residue that has been left after use. For any failure or malfunction, we suggest you contact specialized professionals before disassembling it yourself to avoid further damage.
Is the grinder the same as the polisher?
These two tools have a similar appearance, but what is certain is that these products are machines that differ mainly in their speed of operation.
This depends on the brand, some of the grinders have an engine that provides a speed of up to 10,000 revolutions per minute, while a polisher can move in a range from 600 to 3,000 revolutions per minute, at higher speed, higher power. In the same way, according to the resistance of the material to be polished, you must choose between one machine or another, and also, it is necessary that you select the most suitable disc to perform the task.
The polishers are tools that allow you to perform different maintenance work; they are also suitable for perfecting finishes in a wide variety of metals, wood, fibers, among others. In addition, they work with an elliptical or reciprocating movement that favors dry polishing.
