Eccentric sanders are considered the most effective and versatile tool for polishing and sanding surfaces. In industrial production and in private use, they show the best results in terms of surface finish.

Polishing and sanding is possible through a combination of rotational and eccentric movements of the sole. The sole plate orbits and simultaneously rotates around its axis. This complex abrasive movement allows efficient sanding with minimum imperfections.

Machine weight from 1 to 3 kg, equipped with a round soleplate with Velcro, to which the abrasive wheel on a felt base is fastened. The base plates are available in two diameters: 125 and 150 mm. Machines with 125 mm soleplate are lighter, designed for a smaller area and for more delicate works than the grinders with 150 mm soleplate. Electric motors consume from 200 to 900 W high power ensures high productivity. When installing accessories it is important that the holes on the base of the grinder coincide with the holes of the abrasive wheel, otherwise the dust removal process will be difficult.

Suitable for rough or fine sanding of large surfaces, for sanding between layers of materials and coatings, for polishing, for sanding large surfaces along and across fibres. This type of machines is often used in carpentry and by car painters. Volumetric, profile and curvilinear surfaces are machined with EDM. Working with an eccentric grinder is unlikely to spoil the workpiece: make scuffs, burn the material or overdo with the depth of grinding. Noise and vibration level is less than other types of grinders.

The disadvantages are obvious: the eccentric machines are not suitable for processing internal angles and recesses. Performance is small, in comparison with belt sander.
