Rating of TOP 10 eccentric grinders: review of the best corded and cordless models

Random orbital sanders are power tools that are widely popular. They have become widespread due to their ease of use and high quality grinding. People who want to purchase such a device should find out in advance what an eccentric sander is, the rating of budget ones and their main differences.

EShM - tools used for grinding various surfaces

Features and criteria for choosing eccentric sanders

An eccentric type sander has a design that produces both circular and reciprocating movements .

Due to this, there is no need for repeated processing in the same place, which eliminates the appearance of scratches on the surface.

When purchasing an eccentric sander, you need to pay attention to the following parameters:

1. Rotation speed and range of motion. The optimal speed is 2-4 thousand revolutions per minute. The amplitude should be smaller. This achieves a refined grinding effect. If the grinding is rough, a device with a speed of about 10 thousand per minute is suitable.
2. Performance. When choosing this option, it is worth considering the area and the selected option. Large-scale working surface and high speeds provide greater productivity.
3. Duration of the working cycle. For long-term operation of the device, it is necessary to choose models with high-quality parts and materials.
4. Terms of Use. If the workplace is characterized by excessive dust, high humidity, or a high fire hazard, it is better to choose a model with an increased level of protection.

Note! Pneumatic sanders are considered universal. They can function in any conditions.

What is an eccentric sander

ESM is a tool that appeared in the second half of the last century. The German company Festool was the first to produce such devices. They are used for grinding metal, wood and even plastic.

The quality of processing of these power tools is in no way inferior to models that are equipped with a conventional grinding disc. EShMs also process materials evenly without damaging their surface.

Additional Information! Today, a huge number of such devices are produced and therefore people often do not know how to choose an eccentric sander for wood and metal.
