A little history

The first multi-disc single-brush sander was created in the 1950s. It was developed to facilitate floor cleaning and maintenance tasks in the commercial and industrial sectors. Since then, these sanders have evolved in terms of technology, performance and functionality to meet the needs of users.

It is believed that the first single disc sander was developed and manufactured in Italy. The original concept of the multi-disc single disc sander is attributed to an Italian company that introduced it to the market. They have spread all over the world and are used in various sectors for cleaning and maintenance of floors.

What are its characteristics?
The special feature of the multi-disc single-brush sander is its ability to perform several sanding operations simultaneously. The sanding discs are attached to the rotary table and rotate at high speed, allowing a larger surface to be treated in a single pass.

This type of sander is very often used in the field of floor cleaning and maintenance, especially in commercial premises, hotels, warehouses and other large areas. It is capable of sanding, polishing, stripping, cleaning or polishing different surfaces depending on the type of discs used.

The multi-disc single disc sander therefore saves a considerable amount of time compared to traditional sanders, as it can process large surfaces more quickly. It is also appreciated for its versatility, ease of use and manoeuvrability, making it a commonly used tool by professionals in the sector.

The benefits of a multi-disc single disc sander
Increased efficiency: Thanks to its ability to sand large surfaces in a single pass, the multi-disc single disc sander gets the job done faster than traditional sanders. This saves time and energy when sanding.
Versatility: The multi-disc single disc sander offers the possibility to perform different sanding, polishing, stripping or cleaning operations by simply changing the sanding discs. This makes it suitable for a wide variety of surfaces, whether wood, stone, concrete or other hard materials.
Ease of use: This type of sander is generally designed to be easy to use. It often has an ergonomic handle for a good grip, and the weight is usually well distributed for easy handling.

How does it differ from a belt sander?
How it works: A multi-disc single-brush sander uses a rotating plate with several sanding discs to perform the sanding. The discs rotate rapidly and rub the surface to be sanded to remove unwanted material. In contrast, a belt sander uses an abrasive belt, usually in the form of an endless loop, which is driven by rollers to perform the sanding. The belt moves in a continuous linear motion and removes material as it is applied to the surface.
Working surface: Multi-disc single disc sanders are mainly used for cleaning, polishing and preparing floors. They are ideal for large flat surfaces such as concrete floors, tiles, marble, etc. Belt sanders, on the other hand, are more suitable for sanding flat, narrow surfaces and for shaping edges and contours. They are commonly used for woodworking, including carpentry and furniture making.

Types of abrasive materials : Multi-disc single disc sanders generally use abrasive discs with different grits for sanding, polishing, stripping, etc. Belt sanders use abrasive belts that can be changed to vary the grit size to suit different levels of finish.
Versatility: Multi-disc single disc sanders offer limited versatility in terms of types of work. They are mainly designed for specific floor cleaning and maintenance operations. Belt sanders, on the other hand, offer greater versatility. They can be used for different types of sanding jobs, ranging from roughing to fine finishing, on various materials such as wood, metal, plastic, etc.

For which users?
The multi-disc single disc sander is a versatile tool for tradesmen working on a variety of sites. Its design and functionality make it an ideal choice for cleaning, polishing and preparing floors in environments such as hotels, warehouses, healthcare facilities, schools and many others. It can handle a variety of surfaces, including wood, stone and concrete, thanks to its interchangeable sanding discs. The belt sander, on the other hand, is specifically designed to meet the needs of floor painters. With its linear sanding belt, it is ideally suited to sanding wooden floors, removing imperfections, smoothing the surface and preparing the wood for subsequent finishing. The belt sander is popular with woodworkers because of its ability to work on narrow, flat surfaces, offering precision and efficiency when sanding wood floors.
However, more and more floorers are owning both machines depending on the type of job they are working on.
