  • Orbital sander are grinding tools with a reciprocating plate to which abrasive paper is attached. Often they are associated with eccentric grinders. But these have a spinning plate.
  • Your swinging plate is either rectangular or triangular. The triangular plate models are also called delta grinders.
  • Orbital sander is particularly suitable for sanding large wood surfaces. From paint removal to fine grinding, they can be used for a wide range of applications.

1. How does a sander work?

Bosch relies on safety

In December 2015, toolmaker Bosch Power Tools voluntarily recalled several orbital sander models. The reason was a material defect on a ventilation wheel. Bosch feared that it could lead to serious malfunctions and exchanges the devices for free, Affected are the models: PSS 2 A, PSS 20 A, PSS 190 AC, PSS 200 A, PSS 200 AC, PSS 250 A, PSS 250 AE and PSS 2000 A. Most were manufactured in 2007.

The orbital sander is a grinding tool in which a plate oscillates back and forth, is mounted on the sandpaper. He is sometimes called Sander or Rutscher.

The engine reaches at his Oscillation motions approximately 6,000 to 25,000 revolutions per minute (RPM). It is available with electric motor, but also with a motor driven by compressed air. However, the most common variant is the electric vibratory sander.

With Velcro, the sanding paper on today's devices fixed, Velcro fasteners are flexible textiles that stick together with small barbs. In older models, the paper was pinched at the edges.

Depending on the material you can fast different sandpaper types stapled to the vibrating plate become. As a result, the orbital sander is also a multi-sander and is suitable for the following applications:

  • Pre and post sanding
  • hardwood
  • softwood
  • plywood
  • Paints and resins

Through holes in the sanding pad the orbital sander absorbs the dust.

Through holes in the sandpaper and in the vibration plate is Dust sucked in and collected in the tool. This protects the lungs and eyes of the handyman.

Often the orbital sander is named in the same breath. However, this works differently. With him the sanding plate rotates. This sits eccentrically on the engine (hence the name).

The orbital sander is also suitable for metal, glass and plastic, Because of its flexible attachments, the orbital sander is also often used for polishing or curved workpieces.

For especially large areassuch as a table top or a complete floor, a belt sander is the better choice. In this grinder, the emery paper runs in the form of a conveyor belt through the tool.

Advantages and disadvantages of the orbital sander over the orbital sander:

  • leaves no circular sanding marks
  • good for longitudinal surfaces
  • mainly suitable for wood
  • only grinds when moving back and forth

You can see in the following video how an orbital sander looks like in detail and what other grinders are there:

3. Purchase advice for orbital sanders: You must pay attention to this

Orbital sander comparison 2018: orbital

Especially renovations in old buildings can often speed up a delta sander.

In our comparison of our orbital sander 2018, you will learn how to filter out the best tool for you from countless models. Cheap orbital sander need not be bad and the expensive ones are not necessarily the best.

3.1. Area or angle?

First, you have to decide whether the grinder penetrates into narrow angles, or whether it should be used to smooth mainly large areas. A classic orbital sander test winner will help you little if you want to pre-grind the recesses of the old building doors.

This is the domain of Delta sander. These are usually small and handy, because you often work with them over your head. It penetrates both into narrow angles and very close to straight and curved edges.

Wide areas However, with the small triangular sanding plates are troublesome. The rectangular orbital sander can shine here, Evenly, it wears away in length span and leaves hardly any traces of sanding.

Orbital sander comparison 2018: 2018

For elongated surfaces, the classic orbital sander is the first choice.

Its higher weight does not necessarily have to be a disadvantage when sanding stairs. For doors, it is also advisable to remove them for sanding.

However, if you sand down complete floors, a belt sander may be an option.

3.2. Power and speed

The revolutions per minute (RPM) indicate how fast the motor can potentially rotateto make the sanding pad shake. The higher the speeds, the faster the device can grind.

However, how much the grinder can remove on the surface depends on the power of the motor. This can be seen indirectly: A high wattage is usually an indication that the engine also provides a lot of power. So if you are Not only fast, but also want to sand a lot of material, then you need next to high speeds and high wattage.

More than 200 to 300 watts characterize a powerful orbital sander. Devices that are below this value are useful if the workpiece is sensitive, such as antique furniture.

Above 14,000 rpm make a quick grinder and are good if the surface is very hard or is to be sanded very finely. Coarser grinds need less speed and get by at around 6,000 to 10,000 rpm.

3.3. Which speed would you like?

If you can adjust the speed of your orbital sander, you do not have to buy multiple devices for different grinding jobs. So you have everything combined in one device.

High speeds are useful on hard surfaces and are also needed if the surface is to be ground smoothly.

Low speeds are used for grinding with coarse sandpaper or when the wood is rather soft.

4. Care and cleaning tips

The container on the orbital sanders can be emptied easily.

Orbital sander are easy to clean. Most models They suck and collect dust during grinding and can also be emptied easily.

As a rule, they end up with a dust bag or a container that can easily be pulled off. Other models have a connection for a vacuum cleaner. More is not to be considered in an orbital sander in the care.

5. This is how it is ground

How to use an orbital sander is easily explained: grasp the tool with both hands; a hand is on the handle, where the on / off switch is located. The other hand holds the center of the grinderSo where the engine is located and thus the center of gravity of the machine.

The hand at the counter leads the grinder. The hand at the center gives pressure from above on the tool. The more weight you put on the device, the more chip it can take off. How efficient this is, but also depends on the power of the motor (watts) and the type of sandpaper.

be moderate: If the engine is too weak and you apply too much pressure from above, the tool may lock up and not grind. With a little practice you will quickly find the right size.

As with conventional grinding push the tool back and forth, Therefore, the orbital sander is also called a rider.

tip: Always guide the grinder with the wood grain.

However, the orbital sander is mainly optimized for wood. Although you can work on your Rigipswand also drywall, but the fine gypsum dust very quickly put the engine out of action. Even the best orbital sander can not do this.

If you want to grind plaster, you should rather tackle the classic variant without a motor with a hand grinder, Maybe you could try it with a compressed air grinder, because there the engine is driven by air from a compressor. The compressed air tool absorbs less ambient air and thus less dust.

Almost all orbital sander pick up the dust from the emery surface and collect it in a container.

6. Swing & sing: So that you do not miss the fun of orbiting

Orbital sander comparison 2018: sander

Protective clothing gets the fun of working.

When working with powerful tools, a few safety rules are essential to keep whistling and singing craftsmen. You only need to consider three aspects:

  • protective clothing
  • predictive handling
  • safe storage

protective clothing

Since there is a lot of dust that can be poisonous at times, you should wear a mask and goggles. For example, sanding or sanding painted wood causes the chemicals in it to heat and dissolve. These are harmful in high concentration.

The glasses also protect you from flying around splinter, In addition, you keep the view in a cloud of dust and do not drive with the tool via a cable.

Often you grab for a better grip on the surface to be sanded. Quickly, however, the workman drove the grinder over his thumb, therefore you should always wear gloves.

Headphones are not to be despised so that you can still hear their own satisfied whistling afterwards. because the little machines are extremely loud and little musical.

Handling and attitude

Orbital sander comparison 2018: sander

Proper attitude is an important safety aspect.

Lunge is the magic word here. The weight rests on the rear leg and the front is free to change position, In the event of an emergency, this can protect you from serious injuries if the grinder goes through with you and you slipping forwards or giving in to the workpiece itself.

The tool is always guided away from the body, because if you slip, then the device goes away from the body. These recommendations are also given by the experts of Stiftung Warentest.

storage

For the short break in between you should not stop everything and leave. If you have not gotten used to it anyway, remove the plug from the socket or turn off the compressor.

Professionals also let the Grinder not on the workpiece stand, as this can leave a footprint. Store it lying on its side in a dry place.

If you treat your grinder with care, then he may be able to keep years. Some do-it-yourselfers use ten to twenty year old devices. Manufacturers such as Bosch and Metabo supply their tools with spare parts over a long period of time.

7. Questions and answers around the subject of orbital sander

7.1. What do you use an orbital sander for?

Orbital sander comparison 2018: comparison

For small and filigree workpieces delta sanders are optimal.

An orbital sander comes mainly when sanding wood for use. Here he also serves mostly for editing the surface. That is, either with the rider the Surface honed or lacquer sanded.

The swinging grinder is intended primarily for wide areas. At smaller angles its special variant shines: the delta sander.

7.2. Orbital sander or orbital sander - what's better?

As already mentioned, are Orbital sander for a long time and flat surfaces Well. The Random Orbit Sander can be equipped with flexible attachments and is therefore good for uneven workpieces.

The orbital sander is also designed for woodwork and the Random Orbit Sander for different materials like metal, ceramics or plastic. Because of these properties, the eccentric sander is also happy used in the restoration of carsif, for example, paint is removed and renewed. The accessories also include polishing attachments.

In wood sanding, however, he leaves circular sanding marks. Here, the orbital sander makes a better figure, since it leaves only few traces.

7.3. How much watts for the orbital sander?

If you buy an orbital sander, the wattage is a first indication of a powerful engine. Good machines take on average 200 to 300 watts on, More is better.

The slightly smaller ones Deltaschleifer tend to be used in filigree work, which is why they do not naturally need so much power: 150 to 200 watts are still appropriate here.

7.4. Which sanding paper for the orbital sander?

Orbital sander comparison 2018: sander

There is a matching abrasive paper grade for every surface.

Wood is the specialty of orbital sanders, so there are mainly abrasive paper grades for wood pulp. Current models attach their sanding paper by Velcro on the sanding pad.

So make sure that the sandpaper is compatible with your tool. The holes in the sandpaper should match those on the sanding pad, otherwise the grinder will not suck in the dust properly.

Old equipment pinches their sandpaper, so the paper just has to be long enough and can be trimmed if necessary. If you buy or rent a sander second hand, check beforehand how the sandpaper is attached to the tool.

Sanding experts from Bosch advise: "Grind all materials in several steps and with ever finer grain size." So first choose a paper with one low grain size (e.g., 80) and gradually higher value papers.
