Rating of eccentric sanders for wood: TOP 2021
An eccentric sander allows you to work on the surface without leaving any marks. This is all due to the special trajectory of the grinding attachment. In order for the little-knowledgeable buyer to be able to choose a machine for his needs, we have prepared an article in which we will talk about the intricacies of choice, the features of the technical filling, and also present our rating of wood sanding machines for clarity. Let's get started!

Review of grinding machines - what to look for
Before looking at the rating of grinding machines, we will talk a little about the characteristics so that we understand what we are taking in the store. No one wants to get a “pig in a poke”?
What power of grinding machine do we need?
The main parameter that directly indicates the performance of the device. Good sanders have a power from 200 to 700 W. The higher the indicator, the higher the speed the wood will be polished. On budget devices, the speed can drop sharply if you press the button all the way. And if you use abrasives rather than ordinary discs, the device may not be able to cope with such a load at all.
Therefore, for rough finishing, take machines from 300 W, no less. Additionally, the presence of a function for stabilizing speed under load will be useful. For small jobs or fine grinding, a 250 W unit is sufficient.
Why is it worth looking at the speed of oscillation and rotation at the same time?
These points are inextricably linked. With one revolution of the circle, 2 is created on the gearbox and oscillation is caused. As a result, the amplitude of the movement will always be 2 times greater than the torque of the nozzle. The rotation speed of the latter in devices from the rating of eccentric sanders for wood varies between 5-13 thousand rpm.
The number of turns you choose will affect the surface you are or will ever be working on. The smoother and smoother you want the result, the higher the speed should be. You will never polish a metal part with a grinder, because its speed is not as high as that of an eccentric sander.
Also look at where the device has rotation adjustment. It is important that it is in the most convenient place for you and does not get caught while working.
Points that are important to understand about amplitude
The amplitude of the grinder is the working stroke of the mechanics of the device, which can differ within 2-7 mm. This parameter is permanent and cannot be changed. With a small amplitude, the hand gets less tired, but more time is needed for polishing. This is a good device for finishing surfaces to perfection.
In devices with an indicator of 5-7 mm, grinding is many times faster. But there is also a drawback - the circle leaves noticeable marks that need to be covered with finer sandpaper. To get maximum results and have additional funds, we strongly recommend that you purchase two options at once.You will receive not only complete wood processing, but also pleasure from the work done and the result.
What is the diameter of the sole and what is it for?
The size of the working part (sole) to which the polishing attachment is mounted can be from 70 to 180 mm. The larger this parameter, the wider you will cover the processing plane. The important thing is that this feature only works well with powerful devices. Because if you put a wide platform on a weak engine, you will get a device no faster than an angle grinder.
The advantage of a narrow sole is open possibilities for working in narrow places, grinding corners and small parts. If there are circles or bends on the plane, take circles of about 100-120 mm. For large-scale structures, a platform of 150-180 mm is suitable.
Why is a device with high vibration bad?
The vibration of the device is due to the double movement of the disk and the transmission of torque, vibration of the eccentric. Rattling may also be caused by worn-out abrasive that was used unevenly or was installed incorrectly. All this greatly affects fatigue during grinding.
You are unlikely to see this in the product parameters, so you can only feel it in action. We recommend purchasing devices from the sanding machine rating only in an offline store. You will be able to hold the device and even turn it on without purchasing it yet. Just don’t worry right away - vibration is inherent in all models, without exception. It's just that its strength may be different.
In order to relieve stress from the master’s hands, additional counterweights and damper inserts are inserted into the devices.The outside of the device is covered with rubber inserts to increase hand grip and reduce fatigue after grinding.
Wood sander - rating of the best
Our rating of eccentric sanders includes only those models that have proven themselves through customer reviews on the Internet. Just not those who buy for 10 rubles, but real users.
Makita BO 5031
Pros: Comfortable level of vibration, you can work for a long time without rest, excellent ergonomics of the device. Doesn't get too hot at maximum speed. It is also possible to connect a vacuum cleaner, but it is worth purchasing an adapter. The device has a built-in speed regulator on the body.
Cons: Short wire - 2 m; The dust removal system works at 70-75% - sometimes problems arise with dust removal, and you have to clean everything yourself.
Application: Used for sanding wood and metal. It has proven itself excellent in household carpentry. You can prime and finish your car, or do final sanding of furniture.
Metabo FSX 200 Intec
Why in the rating of grinding machines: The device has a large and convenient case. The eccentric is stabilized, vibration is at an optimal level. You can also connect the vacuum cleaner via an adapter; it does not make loud sounds. The dust removal system also works well.
