Best Eccentric Sanders in 2020

Construction and finishing work is not complete without a sander, which is an essential tool. We have to process surfaces often and quickly, grinding and polishing them, and here such a tool helps out. An eccentric type grinder is popular among devices. It has another name - orbital. Here you will find the ranking of eccentric sanders as of 2020. Here are collected models that have been tested by experience and have proven their reliability.

What is an eccentric sander?

Eccentric sanders are a novelty in the field of tools. They have a random circular path. In 1976, the German company Festool presented a device in which it was possible to achieve simultaneously rotational and reciprocating motion. After 6 years, the company released an industrial model of the grinder.

The eccentric sander (orbital) performs surface finish in quality like a circular sander. But its performance is comparable to devices with a reciprocating motion. The movement of the device circle occurs in a random order, the trajectories do not repeat. Such a constructive solution eliminates the constant grinding of the same places and the appearance of scratches on them.

The English name for this type of device is "Random Orbit Sander" - an orbital sander moving along an arbitrary path.

How to choose an orbital (eccentric type) sander

Each eccentric type tool (orbital sander) is manufactured according to specific conditions. It has a certain set of technical characteristics and is designed for a certain cycle of work and load. For the correct selection of the grinder, factors must be considered:

1. At what speed does the rotation and the amplitude of movement occur. When cleaning and rough grinding are carried out, they use a speed of 10 thousand revolutions per minute, the amplitude of movement is large. This leads to an increase in productivity, but a decrease in the quality of grinding. More sophisticated grinding requires a speed of 2 to 4 thousand revolutions per minute. The range of motion should be less. If you need a universal device, you can purchase and use an eccentric type grinder, in which the speed is regulated and the amplitude of movement reaches 2-3 mm.
2. What performance does the device give. This factor is influenced by the size of the work surface and the selected option. Large working surface and high revs give good performance. The entry-level eccentric sander uses wheels with a diameter of 12.5 cm.Professional devices are supplied with circles with a diameter of 15 cm.
3. Cycle time and production load. In order for the grinding machine to work for a long time and be operated throughout the shift and for long months, the selection of parts and materials is carefully performed for its manufacture. This is the difference between amateur tools and professional grinders. A professional tool with the same technical characteristics can cost much more.
4. In what conditions will the tool be used. For work in places with high humidity, strong dust, a high level of fire hazard, the eccentric type tool is chosen carefully. For this, there are grinding machines with an increased level of protection. Operational data are indicated in the product passport. In such conditions, an eccentric type pneumatic sander can be used, which does not have an electrician. It can be used for all operating conditions.

Rating of the best models

The most worthy entry-level eccentric grinding machines are presented in this section with a price range from 6 to 8 thousand rubles. The main sources of information are customer reviews, which they leave on the forums, or different sites, and are partially selected from various rating categories. The review does not have pneumatic grinders, since working with such a tool requires a compressor with the appropriate properties.
