6 Best Random Orbital Sander Review 2021 [Ultimate Guide]

Best Random Orbital Sander

Most construction projects will require sanding of different surfaces. It may be sanding furniture or wooden floors to smoothen out cracks or rough spots on the surface. Or perhaps scrubbing off old paint so that a wall can be painted anew. A random orbital sander is a handheld tool used for ultra-smooth sanding. It produces vibrations in tiny circles that moves back and forth, contrary to the constant circular motion of a rotary sander, which enables it to produce little to no swirl patterns on the surface. Random orbital sanders also come in a variant known as floor orbital sanders that has a long handle that makes it perfect for sanding large surfaces.

Since the sand disk spins simultaneously and randomly, unlike other sanders, no marks will be left on the wood. When two portions of wood need to be fastened at right angles, the random orbital sander will be the perfect tool since the sanding disk's random rotation will not adhere to the wood grain. It has proven to have very significant advantages over other sanders due to the accessibility and efficiency it offers.

Let us, therefore, scratch the surface deeper and check out the best sanders available in the market!

Ever since their invention in the late 1970s, many people have used and praised the capabilities of the random orbital sander. Users have always praised its dust collection system. Your sander will have a dust-collecting bag attached to its back. Some sanders even have filters to separate the different particles it will suck in. It has holes where dust particles are pulled from the surface while sanding and into the sander itself, then into the dust collection chamber.

Do you have headaches every time your old wall needs sanding? With this sander, this will not be a problem anymore. It is simple and easy to use; just a few minutes into sanding, you will feel like you've been sanding for over ten years. In addition, it is not heavy and will let you finish your project in no time.

This is an excellent sander that can be used for both aggressive and regular sanding. Switching between these two modes can be done by just pressing on a switch. The aggressive sanding mode is turbo driven, whereas the fine finishing mode is just normally driven. Moreover, this sander will give you a uniform and neat surface without swirl marks. This is because a braking system is integrated into your pad, thus dampening it, allowing for a finer finish compared to other sanders.

Furthermore, you won't have to worry about getting respiratory complications from your sanding work. This sander has a wonderful dust collection system that comes with hoses and a vacuum cleaner to remove dust from your working surface effectively. This sander's operating speed is relatively fast and can be varied according to your tasks' needs; this is because a powerful 6.5 amp motor powers it.

Moreover, this sander is a cut above the competition because of its great ergonomic design. Its handgrip is designed to fit in your hand comfortably. It is also easy to operate, thus giving you an enjoyable experience with your sanding. Additionally, the pads of this sand have many holes that are compatible with many disks. This gives you the freedom to choose the abrasive disk you wish to use. The only complaints users have had is when overhead surfaces need sanding, whereby the sander may feel quite heavy.

Ultimate Buying Guide

When looking for a random orbital sander, you must first consider the nature of the work you will be carrying out. If your job is just regular sanding where a subtle finish is expected, go for a sander with a low power rating. More aggressive sanding work will require a higher power rating like that of the Bosch 1250DEVS.

A dust collection system that is effective is also very important. You should look for a sander that removes most, if not all, dust on your working surface. This is to provide you a clean environment and reduce the risk of pulmonary conditions.

Handheld sanders require to be portable. Therefore, look for one that is light so that you can carry it comfortably within your site. Always get a sander that produces little vibration since too much would produce a lot of noise, cause fatigue, and produce poor results. Lastly, speed control systems are very critical. This is because you will have to vary the sander's speed several times to achieve the best finish.

Frequently Asked Questions 

Q: What Is The Best Random Orbital Sander?

A: This is entirely dependent on what your task entails – its needs and expectations. A large floor random orbital sander will be suitable for contractors who undertake frequent and big construction projects. You should opt to go for a handheld sander that is smaller and lighter for domestic use.

If your electricity connection is not reliable or do not want to be tethered to a single spot, you can go for a handheld sander that is air powered. You also have to consider the labor force to perform the task. Smaller and less complicated handheld sanders will be more suitable for someone sanding for the first time rather than giving him the complex floor sander.

The frequency of use of the sander is another major factor to consider. It will be illogical to buy a very large, complicated, and expensive floor sander with rollers for a one time project. This kind of machine would be suitable for contractors who will use it regularly.

Q: How does an orbital sander differ from a normal sander?

A: The main difference is the oscillatory movement of the random orbital sander. The orbital sander, as the name suggests, moves in an orbit in a circular path. The random orbital sander, on the other hand, not only moves circularly, but the motion also has an oscillation. As a result of this back and forth movement, the sander can produce a neat smooth finish without swirls. The oscillation also moves on the working surface regardless of the direction of the grain, thus giving you a perfect finish.

Q: How Does A Random Orbital Sander Work?

A: As the name suggests: 'orbital', the sander has a circular motion. This circular motion, if alone, will result in a wood surface full of swirls. This is, however, avoided by the oscillatory movement of the sander. It moves back and forth in a random manner, which ensures any possible scratches are removed. The result is a neat, smooth, and uniform surface. Unlike other sanders that use square pads, this sander uses a round pad. This is ideal because it does not get stuck into corners as easily as a square pad.

Final Verdict & Recommendation

The sanders we have seen above are all great tools for any woodworker. Each of the above sanders is suited to perform particular actions specifically. They all are tools of high quality and with great features such as dust collection systems, variable speeds, and many more.

Suppose you aim at achieving the neatest and most uniform surface. I highly recommend that you purchase a Bosch ROS20VSC Palm Sander 2.5 amp corded speed sander. It has variable speeds of 7,500 and 12,000 OMP, which are relatively fast, making it very efficient.

However, as previously mentioned, always consider the job specifications of your project first, then with this in mind, choose the most suitable sander. Last but not least, as for all tools and machines, safety precautions are essential. Always handle your sander with care, either when using it or storing it. There is still a possibility of physical injuries when mishandled. Remember to replace dull sanding discs since these tend to overheat when used.
