Shopping Guide: Everything you should know about the polisher
When it comes to correcting or removing paint from a vehicle, totally or partially, correcting imperfections or removing traces of rust and material, polishers are the right tools. Next, we present a buying guide where you will learn everything you need about polishers and their most important features.
What is a polisher?
Polishers are power tools whose versatility is important for polishing ridges or edges, as well as for loosening rivets, rounding corners, and repairing damage to metal and plastic surfaces. For this reason they are widely used in various processes of sanding or surface edging, especially in the mechanical industries.
Although grinders have special polishing discs, in reality they are completely different machines. Polishers cannot be used for cutting work and also have two types of motion that grinders do not have.
What is a polisher for?
Polishers are used to eliminate any type of damage on metal and plastic surfaces, obtaining the original shine of a new piece. For this reason they are widely used in sheet metal working and painting workshops. With a polisher you can also remove old paint, wallpaper and restore shine to old surfaces exposed to the sun.
In the market you will find a large variety of models. You can choose a larger and more professional machine or a domestic model equipped with an accessory case, for different jobs. In any case, polishers are very useful machines even if they require a certain skill in order not to leave streaks.
How is a polisher composed?
Basically, polishers consist of three parts, which you should know as best as possible in order to handle the tool correctly. Some parts, since the discs are interchangeable, it is important that you know how to differentiate them. Here are the different parts of a polisher:
- Handle: with ergonomic features, it is the key piece of the polisher, as it incorporates the activation trigger of the polisher. It must be of non-conductive material.
- Body: it is the part that protects the internal parts and the motor of the tool. The best tools have IP watertight systems that protect them from dust and moisture.
- Disc: abrasive, rotating and of different gradations depending on the need for polishing. This is the main accessory of the polisher.
- Cable or battery – provide power to the machine. The batteries must be lithium-ion, as they have no memory effect.
What are the uses of a polisher?
For both home and industry, an electric polisher is a fundamental tool. With it, you can do a wide variety of jobs, from removing damage to a body to polishing or leaving a piece of shiny wood for a carpentry project. As you can see, they are very versatile.
Next, we present a table with the main uses of polishers:
|The most used in the professional field is the rotary press.||Used to maintain glossy patinas and finishes.|
|Vehicle body repair.||Cleaning and polishing of the car body.|
|Sheet metal and metal parts polishing.|
|Polishing and cleaning of parts and boards in wood and plastic.|
What types of polisher are there?
There are basically two types of polishers: rotary (circular) and double action (orbital). Rotary ones are the most popular, their maneuverability requires skill and experience, which is why double action ones have appeared, easier to use and capable of obtaining perfect finishes even in the hands of beginners.
The key difference between one type and another is in the way the polishing disc or pad rotates. The presses rotate on their axis in a perfect circle and speed is measured in revolutions per minute (RPM). The double action rotates circularly and oscillates describing elliptical orbits and is measured in oscillations per minute.
|Type of polisher||Speed||Speed control||Ergonomics||Features|

|Electronic.||Comfortable.||Uniform distribution of abrasives.

Corded or battery-powered polisher?
One of the most common questions that can arise is: which is best: a battery-powered or an electric polisher? It is a common debate in the field of power tools, as every day more and more manufacturers opt for battery-powered products and stop producing corded machines, as they are more comfortable for users.
There are some aspects that do not change, for example, any corded tool will always be more powerful and, moreover, will always be ready for use, while cordless tools can leave you stationary at an inappropriate time, especially when the batteries run out. getting old.
In the following table we compare the pros and cons of cordless and cordless polishers:
|Battery-powered polisher||Lithium-ion batteries have a long life.

Now that you know what polishers are, why buy one and how to use it, it’s time to choose the one that best suits your needs. Choosing a polisher can become a daunting task, which can get complicated if you don’t know what factors make the difference between a good polisher and the best of all. This is why we have selected what we believe are the most important purchase criteria:
- Speed control
The first thing to consider is the use you will make of it. Do you want a polisher for your car? Do you want one for DIY jobs? A floor polisher? It is not the same if you think of a sporadic use, for example every three or four months to polish the car, than a frequent use for different types of surfaces or for projects of a certain size.
For occasional use, a simple, basic, double action polisher at an affordable price will suffice. These cars are ideal for beginners, as they leave no marks and you can familiarize yourself with the process with them without damaging your car. These polishers, on the other hand, have little power and take a long time to process, so they’re not ideal for professionals.
Rotary polishers have more power and their speed is measured in RPM. They are the most common and the most used in both professional and domestic settings. The speed range of these machines is between 700 and 2800 RPM, considering any machine between 1100 and 2000 RPM suitable.
On the other hand, double action polishers, also known as rotary orbital polishers, have less power but their results are finer. They are ideal for beginners as they do not easily leave polishing marks. When it orbits on its axis, its speed is measured in OPMs (orbits per minute), with intervals ranging from 4,000 to 6,000 OPMs.
Speed control is an important factor in buying a polisher. Being able to adjust the speed electronically will be beneficial, as you will have more control over the machine and, therefore, you will get better finishes. Control will become an essential element if you need high quality and professional finishes.
To give you an idea, delicate jobs require low speeds, while large, coarse jobs require high speeds. Obviously, if you use too high speeds, you run the risk of destroying the paint. If the speed is too low, it could take hours and sometimes not achieve the result.
Ergonomics is a factor to consider in all our purchases, and even more so when we talk about electric and heavy machines. If you plan to spend many hours working with the polisher, the ideal is that it fits well on your hands and body. This can be a somewhat subjective factor, as each body is different and each person has unique strength and endurance.
It is generally best to test the machine in person before purchasing and see how it fits. If that’s not possible, you can always look at comments from other buyers. It is important to pay attention to the weight, as it can affect both its power and its comfort.
On the market you will find basically two types of polishers. Random orbital and rotary ones. They differ in the mechanism and type of movement they offer, which will be decisive depending on the work you want to do. Orbitals are the most common on the market and perform circular movements, are efficient, but require some experience.
Unlike rotary ones, which often leave polishing marks (called holograms), orbitals are easier to use. These are suitable for beginners, although they are less powerful, harder to find and a little more expensive, so in the end you will have to calculate if they are worth the money.
