What is an orbital sander?
An eccentric sander is a type of orbital sander with eccentrically mounted grinding disc, which simultaneously executes rotating and oscillating movements. In contrast to the conventional orbital sander, the grinding wheel can be round or rectangular. Equipped with triangular sanding shoe, the random orbit sander corresponds to a delta sander.
As the abrasive grains never stay longer in one place, a very fine and even abrasive pattern is created by simultaneously guiding the sander over the surface. The random orbit sander is always used parallel to the working surface. The varying amount of ablation results from free or guided rotation using a gear. The power supply of eccentric grinders can be provided by a rechargeable battery, by an external power supply or by compressed air.
The random orbital sander is a special electrical tool that can be used multi-sided and is guided by hand. Especially for various grinding work this tool is used again and again.
There are different designs for the random orbital sanders. Depending on the surface to be sanded, there are also different attachments with corresponding grain . Not only coarse grinding can be performed, but surfaces can also be softly ground.
The random orbit sander works with a grinding surface that rotates. The grinding disc sits eccentrically on the working surface, which means that additional circular movements are carried out in the centre of the grinding wheel .
This circumstance prevents scoring , which could be caused, for example, by an orbital sander.
By using an eccentric sander, surfaces are not only ground more evenly , but also with significantly lower workload. In particular wood, metals and plastics can be processed with the random orbital sander.
For this, however, the grinding wheel must always be selected accordingly. In addition, there are already random orbital sanders that can also process glass. With different steps the surfaces can be ground with weak or strong grinding movements.
Most random orbital sanders have numerous steps that can be selected by means of a rotary knob or push button. The great advantage is that all operations can be performed with only one device . Some models also have an integrated dust bag for emerging dust, which allows the particles to get directly into the bag and largely prevents massive dust generation.
Why does an orbital sander grind finer than an orbital sander?
The circular motion of the orbital sander generates visible small curls in the surface when the machine is moved too little. This is particularly annoying as the surface has to be reworked again. However, not only the movement itself, but also the size of the internal movement has an influence on the grinding pattern.
Now the turns and oscillations come into play. Although their movement intensity has no effect on the grinding pattern, the more often the grinding movement is performed, the higher the ablation. If you are about to make a purchase decision, look at the technical specifications to see which oscillating circuitsthe random orbital sander has the test winner. If you want to achieve high material removal on large surfaces, an eccentric sander with a high rotational speed and oscillation rate as well as large own motion is ideally suited for this purpose. If, however, you are looking for a machine for fine grinding, the random orbital sander should perform as small an oscillating circuit as possible.
Where does the random orbital sander get its name from?
The word “excentric” comes from the Latin and Greek vocabulary. It is the opposite of “concentric” and means “without common center“. Originally scholars used the term in astronomy to describe the orbits of planets.
In mechanics, a disc is eccentric if its rotation point is outside the center. Eccentric circles are those without a common centre: many fairground rides use this movement.
The eccentric movement of the grinding disc is a intentional unbalance, which is referred to as an “oscillating circuit” in the technical specifications. The higher this unbalance is, the finer the surface will be smoothed. An eccentric value of “zero” thus does not cause any excentric movement. A common resonant circuit is 2.0 mm. The plate diameter of an eccentric sander is usually 12.5 cm to 15 cm.
random orbital sander vs. delta sander
The delta sander is an ordinary orbital sander, which is particularly suitable for corners and angled workpieces due to its pointed grinding attachment. This triangular shape is an advantage over the round plate of the random orbit sander when it comes to precise corner preparation. On the other hand, the delta grinder is relatively small, which is disadvantageous for grinding large surfaces. Since the delta sander only grinds with an oscillating motion, the eccentric sander achieves a more attractive end result.
Orbital sander vs. belt sander
The belt grinder has a so-called endless grinding system in which a ring-shaped belt is always pulled in one direction over the grinding plate. It is used for wooden floors, parquet and other large wooden surfaces which are to be sanded in grain direction. The endless sanding belt produces a typical sanding pattern due to its linear movement, which does not produce the even surface smoothing of an eccentric sander. Even the smoothing removal of worn surfaces is not the actual purpose of the rather cumbersome belt grinder . An eccentric sander produces a much finer surface, such as is desired on tabletops, for example.
Occentric sander vs. angle grinder
An angle grinder, colloquially called “flex”, also has a round disc. An angular gear sets the grinding wheel only in rotation without oscillation, as it characterizes the random orbit sander. The Flexshe mainly performs coarser tasks, such as cutting stone slabs, metal pipes and grinding welding seams and surfaces. If the optics are important, an orbital sander performs better at least with Finish.
Random orbital sander vs. multi sander
The multi-grinder is equipped with versatile accessories, as its name suggests. Round, triangular, rectangular and angled attachments are so small in size that fine work in particular can be carried out very precisely. The overall handy multi-grinder is designed to work out grooves, joints and profiles, but for larger tasks and perfect surfaces the random orbital sander has a clear advantage.
Orbital sander vs. polishing machine
Polishing machine and random orbit sander are similar at first glance. Both use round grinding attachments, whereby the polishing machine works with felt or polishing sponge. It makes more sense to buy a random orbit sander with polishing attachment, as this tool is used for much more tasks on various materials than to polish only lacquer.
Orbital sander vs. rotary sander
The rotary grinder generates the grinding performance by rotary motion. Its round attachment is suitable for flat, curved and uneven surfaces of various materials. As the respective random orbit sander test of two well-known DIY magazines from May and June 2017 showed, the optical quality of the surface with the eccentrically rotating and oscillating grinding disc succeeds far more satisfactory than with the rotary sander. The removal rate is also more effective.
The tasks of an orbital sander
Do-it-yourselfers and craftsmen use the random orbit sander for very different projects. The orbital sander is mainly used for work on hard and soft wood, while an orbital sander is a true multital for all kinds of construction and renovation work.
Which abrasive paper does the random orbital sander need?
In order to process a material with the random orbit sander, you need suitable abrasive paper. Pay attention to the number of holes, the colour of the leaves and the different grain size. The colour system is intended to make it easier for the customer to make a choice. Some manufacturers have their own colour code, but usually common types of abrasive paper are marked materials in the same colours.
What do the colours of sandpaper mean?
The most frequently used abrasive paper is on the sanding side wine-red. This grade is intended for processing wood and lacquered surfaces. The reverse side is brown and the grain size is indicated on it.
Abrasive paper with light grey working surface is used for sanding plastic, car paint or for smoothing putty (filler). The grey variety usually has a blue reverse side made of tear-resistant textile material. With fine and very fine grit sizes, particularly smooth surfaces can be created by wet sanding in several passes.
What grain size for which surface?
Before we discuss the grain size, we come to the spreading of the abrasive. Depending on the type of abrasive paper, the individual grains are applied to the backing paper at different distances from each other. This allows the abrasive particles to penetrate flatter or deeper into the surface . If you clamp a paper with far apart abrasive grains, the material removal is very aggressive. A grade with tightscattered grain size protects the workpiece, but more friction generates more heat. In principle, the spreading depends on the grain size.
The grain size of the sandpaper is indicated with a number on the paper side. The smaller this number is, the coarser is the grain size, higher numbers indicate finer grain sizes. In the trade you get grains which range from 12 to 5000 according to DIN 69176. The letter P in front of the grain number indicates the quality standard which corresponds to DIN 69176. Grain sizes between 40 and 120 are used for large removal, to compensate for scratches and for pre-sanding of a wood surface. With a medium-fine grain size of 150 to 180, old paint layers can be sanded off wood surfaces, and metal surfaces can also be roughened. A wood surface is prepared for varnishing with 220 to 360 grain. The finest grain size 5000 is used for painting car body parts. Grinding always starts with coarse grains and changes to a finer variety at each subsequent step.
Occentric sander helps with renovation
The random orbit sander does a good job renovating. Overpainting several coatings is not a good solution. Because you find the existing apricot orange horrible and the wall is to be painted in classic white, you must completely remove the old paint. The random orbital sander is a effective aid.
The random orbital sander for different materials
- With a high-performance eccentric test winner, even coarsely cut artificial and natural stonecan be ground and polished to an excellent fit. This would be the case, for example, with the cladding of an open chimney or with the custom worktop in the kitchen.
- The sealing or processing of Metal can be carried out by any do-it-yourself enthusiast with an orbital sander. During reworking and smoothing, more bulging weld seams also unsightly grinding marks disappear from the surface.
- Self Concrete you can grind and polish with an eccentric grinder. Use a robust grinding wheel that can cope with the hard material. Well suited for these tasks are diamond grinding wheels. In the trade you receive different polishing attachments for high performance grinders.
- The random orbit sander is ideal for materials in dry construction. If you would like to divide a room by means of a Rigipswand, the substrate must be levelled and sanded before painting. With an eccentric sander these preliminary work can be done much faster than working with natural stone or concrete.
- For any sanding work on outdoor wood the random orbital sander is ideally suited. If you have a Carport or a Terrace cover made of wood, these extensions require regular Care in order to remain attractive and safe. Especially on uneven surfaces, an orbital sander is easier to operate than an orbital sander. The end result is a visibly better result.With each grinding cycle, a smaller grain size refines the surface structure. The wood dust can be removed from the working area immediately with a vacuum cleaner attachment.
- Wood in old flats also needs to be refreshed from time to time. At the top of the renovation list are doors that need to be sanded down and repainted. Also old chests of drawers and cupboards are grateful for a renovation. Since the random orbit sander is especially recommended for uneven surfaces, cassette doors and frames will soon shine in new splendour. If there are too many profiles and carvings, we recommend using a specialist to avoid damage to historic furniture.
- The round grinding disc achieves more stock removal than a delta or orbital sander, the comparison showed in an random orbital sander test. Therefore, the random orbit sander is suitable for generous machining large surfaces. Alternatively, you can work even more effectively with a professional belt grinder if you are less concerned with even surfaces.
Technical Details of an Random Orbital Sander
The technical equipment of the random orbital sander is decisive for the performance, the quality of the surface and comfortable handling. With the right accessories do-it-yourselfers can do their work more precisely and in less time. In the long run, it always pays to inform yourself about the properties of the random orbital sander, because a less good sanding pattern is still visible even through a coating.
What optional power supply does the random orbital sander have?
In most cases, where frequent use is to be expected, the purchase of an orbital sander with electrical connection or a pneumatic drive is required. Most users opt for a random orbital sander test winner that can easily be connected to the next socket. The variant operated with compressed air must be connected to a compressor.
Random orbital sanders with pneumatic drive are therefore usually located in the Workshop of a craftsman's workshop. As a third option, random orbital sanders with battery operation are available. The price for the greatest possible mobility and completely free handling is the lower performance.
Do random orbital sanders with dust extraction make sense?
For intensive commercial or private usage we recommend an random orbit sander with connection option to a vacuum cleaner or a exhaust system. Thus the dust, which is produced in considerable quantities during grinding, is immediately absorbed by the dust extraction system on the unit. Not only does the working area remain well visible and clean, fine dust is a potential risk. Inhaled wood dust, which is usually still contaminated with lacquer particles or wood preservatives, leads in the long run to lung diseases, eye irritation and allergies. Not to mention the dirt that creeps under your clothes. In addition, one single spark is sufficient, which can be released when the light switch is switched on, in order to trigger a devastating dust explosion.
Orbital sander with dust bag
Dust-free air is a real boon for long-term and large-area grinding work. Therefore, when making your purchase decision, make sure you have the appropriate accessories for the vacuum cleaner connection. If you use the random orbital sander only occasionally, the abrasion can be collected in a pluggable cassette or a smaller dust bag. The dust is immediately sucked in through the openings in the grinding wheel.
Orbital sander with soft start
When the engine is switched on, it runs a little slower to full power instead of “starting” immediately. The initial throttling protects the gear and allows comfortable attachment of the grinding disc to the material.
How many watts of power do random orbital sanders have?
High-quality machines have a drive power between 300 Watt and 400 Watt. Even with modern battery devices, manufacturers have been able to increase performance, but after a maximum of quarter of an hourthe capacity of the batteries is exhausted.
What speeds should an orbital sander achieve?
The stronger the drive of the grinder is, the higher the number of revolutions per minute the device performs. The number of revolutions required depends on the Material you want to edit. On average, random orbital sanders show test winners between 5000 and 26,000 oscillations per minute, which can be set in power levels. During grinding > the number of revolutions decreases due to the pressure of the dead weight and the friction resistance. A five millimeter large swing radius allows faster and more effective working than a model with 1.5 mm swing radius.
What are the advantages of a gear random orbital sander?
A gear random orbit sander can be adjusted for eccentric, orbital and gear random orbital grinding motion. The grinding movement is similar to that of a simple random orbital sander, but in contrast to this, the connected gear performs the rotation in a forced control. This means that the plate rotates even under high pressure on the device. This mode is suitable for coarse grinding and also for polishing, as the number of revolutions is relatively low at 1000 rpm.
Occentric sander with additional handle
A second handle enables precise guidance of the machine especially on curved surfaces and strong vibrations neutralize themselves on uneven surfaces. The ergonomic handling through two-handed operation is noticeable by a more relaxed posture, which relieves the back. The auxiliary handle is an important feature that should not be missing from frequent use of the random orbital sander. Smooth handling produces a more even grinding pattern.
Is it possible with an eccentric sander wet grinding?
With a special attachment for wet abrasive paper, the random orbit sander can produce mirror-smooth surfaces. This is absolutely necessary for the painting of car body parts and for other fine work.
Which grinding disc diameter is required?
If you need the random orbit sander mainly for large flat surfaces, we recommend 150 mm diameter. Another common size is 125 mm, which is suitable for handy guidance for finer work. Look for matching openings in the sandpaper for dust extraction to work.
Uniform grinding results with interface pad
A thicker protective fleece made of foam significantly increases the durability of the Velcro surface of the backing pad. The soft layer is velcroed between the abrasive disc and the abrasive paper. Roundings more evencan be machined and the Velcro surface on the grinding disc wear not so fast. With some random orbital sanders, simple abrasive paper can optionally be clamped with clamps.
What is the service life of an orbital sander?
With good care and regular maintenance, an orbital sander theoretically achieves at least ten yearsservice life until significant drive parts wear out. The tax depreciation mobile random orbit sander is possible after eight years.
How does an orbital sander work?
There are different designs for random orbital sanders. It also determines how these work.
The classic random orbital sander
With the help of a motor, the oscillating disk attached to the underside is brought into rotation. The abrasive paper is then placed on the surface, which is then guided over the surfaces to be treated. The grinding plate is on these models usually rectangular and moves with circular vibration.
The random orbital sander in the actual sense
In contrast to the classic model , the random orbit sander has a grinding wheel which is set in rotating motion. Additional The center of this grinding wheel also performs Circular movements. The round grinding disc on the underside sits eccentrically on the surface in most cases.
When grinding, the random orbital sander is always guided parallel to the surface. This requires a little tact and sensitivity. Gentle pressure is usually sufficient to evenly sand the surface.
The electric drive sets the random orbital sander in motion. Before grinding it should be checked whether the correct grinding wheel is located on the underside .
With uniform rotations, the tool glides over the surface and removes layer by layer. The oscillating motion of the random orbital sander is additionally determined by the rotation emanating from the grinding disc. This is why the grinding disc of an eccentric sander is always round. Due to the so-called “disappearing” grinding the grinding result is very fine with this hand-guided tool . In addition, the oscillating pad itself does not rotate on the machine at high pressure.
The gear random orbit sander
The geared random orbital sander plays a special role in this tool, because it actually works like different machines. The gear random orbital sander comprises the activities of a conventional random orbital sander, a orbital sander and a polishing unit. The grinding movements differ depending on the application and function. On most models, the different functions can be selected by means of the controller or pushbutton.
The grinding movement of this unit is very similar to that of the random orbit sander, but the rotation is still controlled by the gear connected , which causes the disc to rotate even at high pressure on the unit. In this setting the removal of surfaces is much more efficient, which is why the gear random orbit sander is often used for very coarse surfaces.
What are the advantages of an orbital sander?
The random orbit sander is a hand-held tool that offers a number of advantages. In general, this tool is relatively light and can be guided with one hand gently over the surfaces. But there are also other advantages, which can be shown with this handicraft tool.
- Smooth operation
With the help of the random orbit sander, it is possible to grind surfaces evenly. Gentle pressure is already sufficient and the layers are gradually removed. In addition, when grinding with the random orbital sander, scores hardly occur if the unit is used uniformly.
Nevertheless, grinding with this hand tool requires some practice. That is why expensive furniture should not be sanded at the beginning. It is recommended to exercise in advance on surfaces which do not have to be used afterwards. In this way a feeling can be gained with the handling of this machine.
- Numerous grinding wheels
The random orbit sander can be used for different surfaces. Usually metals, woods and plastics are sanded with this device. But there are already some models with which glass can be processed.
Please note that for each material different grinding wheels are available. In addition, there are also different grain sizes. Depending on the nature of the surface, the correct grain size should be selected. Coarse surfaces require coarse grain and vice versa.
- Low power consumption
The random orbital sander is operated by current. Just turn on the switch and you're ready to go. Since most models already have relatively low weight, the device can be moved over the surface with little effort. In addition, the random orbital sander rests on the surface, which also reduces the amount of force required.
Nevertheless > care should be taken that the random orbital sander is guided in such a way that is not supported, otherwise uneven grinding results may occur. When working with the random orbital sander, a small amount of force is required, but some tact should also be included.
- The round grinding wheel
This hand-guided tool is characterised by the fact that it has a round grinding disc which is set in rotation by the motor. The grinding disc on the random orbital sander, however, is not centered, as on the orbital sander, but is eccentric to the drive of the device.
This design prevents the classic grooves during grinding, as is the case with other grinding machines. Since the random orbital sander moves over the surface in uniform movements, the grinding process not only saves time , but also lighter .
- Clean working
Most models already have a collection bag . Fine particles produced during grinding are transported directly into the bag by means of a tube. This results in the great advantage that the grinding process does not produce too large a dust generation.
Test criteria – how did test subjects test the random orbital sander?
If you are considering buying an orbital sander, you should consider a few things. In a series of tests, test persons scrutinized some models and evaluated them according to various test criteria.
Packaging and delivery
One of the first aspects that catch the eye when buying an orbital sander is the packaging. The testers checked whether the different models were packed in such a way that no damage was caused during transport . Since we ordered all the random orbital sanders on the Internet, we were also able to take a close look at this test criterion.
The performance itself plays only a minor role in the random orbital sander . Rather, in tests attention was paid to the quality of the abrasive paper, because this is the decisive factor for good or bad grinding results. For conventional use, performances between 200 and 450 Watt are perfectly sufficient.
Extraordinarily high-quality random orbital sanders also feature a so-called disc brake, enabling careful and targeted sanding of surfaces. The disc brake throttles the speed as soon as the random orbit sander touches the surface. This not only increases work safety , but also workpiece protection , which largely avoids unsightly grooves and furrows.
In order to achieve good results with different materials, the random orbit sander should be equipped with control electronics. So the speed with which the random orbital sander is guided over the surfaces can be controlled . In general, these tools work at very high speeds, which can reach about 12,000 revolutions per minute.
It would also be an advantage if the random orbital sander also had a so-called duo orbital setting, as this makes the grinding process even easier . However, this setting is only found on high-quality random orbital sanders and was only evaluated if the models had it.
The backing pad
The size, the quality and the performance of the grinding disc were also the focus of interest in the test series. For the size at least a diameter of about 80 to 150 mm should be achieved. However, the size of the grinding disc is of course always dependent on which surfaces are being machined. For larger surfaces also larger diameters should be considered. This test criterion was of course taken into account during the tests. Small discs can be used where it is necessary for the random orbit sander to adapt to roundings or unevenness.
Functions in test
Each random orbital sander is listed in external tests with its data and facts, which are gradually put under the microscope in practical tests. Here we pay meticulous attention to whether the information, which is listed by the manufacturer, can actually be implemented in practice. In addition to the functions, handling and commissioning also play a decisive role in a test.
What functions are important for the random orbital sander?
The backing pad
The grinding disc on the random orbital sander is basically the up and down. Depending on size, quality and performance, corresponding grinding results can be achieved.
The random orbital sander is electronically driven, which is why power – explicitly the number of watts – also plays a decisive role. However, it should be noted that even random orbital sanders with a small number of watts can still provide good performance if the grinding disc is correspondingly good. In general, the number of watts is between 200 and 450 watts for these craft tools.
In order for surfaces to be machined according to their properties and requirements , the corresponding speed must be selectable. This is usually possible by means of controllers located directly on the device.
The random orbital sander should have a collection bag so that the grinding process can take place as without generating large amounts of dust. On most models, this is connected to a tube directly behind the grinding disc so that particles can be transported directly into the bag. The collecting bag ensures gentle working, as the particles are not inhaled.
The top 5 random orbit sander brands
There are numerous random orbital sanders from different manufacturers on the market. The best known and Top 5 were examined by us under the magnifying glass.
Order sander buy – what does an orbital sander cost?
Anyone who wants to buy an orbital sander will always have the price in mind in addition to the functions. With random orbital sanders, low-priced models start at 70 Euro, with hardly any upper limits. However, should not be saved in the wrong place when buying the random orbit sander . If you want good results and performance, you should dig a little deeper into your pocket.
In general, it can be assumed that high-quality random orbital sanders are already around 150 Euro. The price reflects not only the quality, but also the functions. Anyone who wants to buy this handicraft tool should know in advance for which purpose the random orbital sander is used. Thus, functions that are not needed can be excluded in advance, which of course has a significant effect on the price .
Internet vs. specialised trade – where is the best place to buy my random orbit sander?
Who would like itself to be advised extensively , before it strikes with the purchase of an eccentric sander, for that the specialized trade is exactly correct. Here competent employees are available, who can certainly help with the purchase decision.
Although it should be remembered that most employees work on commission, which means that cheap random orbital sanders that also do a good job are unlikely to be mentioned. In addition, there is the great advantage that the device can be taken home right away when you buy it from a specialist retailer.
Those who can wait a few days for the random orbit sander should not ignore the purchase on the Internet. Although personal consultation is not possible here, a picture of the different models can still be obtained on the basis of different test and experience reports. In addition, the Internet offers the possibility that prices can easily be compared with each other. Just a few mouse clicks are enough to find the best offers.
In addition most offerers in the Internet already offer free dispatch . The Internet, with its unlimited possibilities, not only offers the most common models, as is generally the case in the specialist trade, but also features a wide range of devices. There is a great possibility that even models that may no longer be up to date, but still provide really solid services at reasonable prices, can be found.
Another advantage is the transport. Although the random orbital sander is not particularly heavy and bulky, it still has to be transported home by the specialist trade. When buying on the Internet this transport can be saved , because the postman brings the package within a few days to the front door.
The expenditure of time can also be evaluated as positive. While the time needed to get to and from the specialist shop, wait for the employee and wait at the checkout must be included in the calculation, the purchase on the Internet is simply a matter of comparison and a few mouse clicks. You don't even have to leave your own four walls for this.
