What Is a Random Orbital Sander

Random orbital sanders are hand-held tools that provduce rotational and eccentric movements. Thereby, the disc rotates in orbit while it scrolls around its own axis (in a so-called random orbital pattern). This technique enables random orbital sanders, or random orbits, to produce particularly smooth surface finishes, much better than all other types of sanders (read more).

With a weight between 1 and 3 kg, these types of sander are portable and convenient to operate. They usually have a round sole on which sanding discs are fixed with Velcro. The usual diameters are 125mm and 150mm while the motors have between 200 and 900 W.

Advantages of Random Orbital Sanders

Random orbital sanders are comparatively safe and easy to operate thanks to the low level of vibration and their low wide. One of their main advantages is the smoothness of their results which is due to the specific way they move the sanding discs.

Disadvantages of Random Orbital Sanders

This type of sander is less versatile than other handtools, when compared to angle grinders, for instance.  They are also less efficient in surface removal, compared to belt sanders, and cannot reach every corner as palm or mouse sanders do.

However, this specialization makes them second to none when perfectly sanded surfaces, typically wood, are required.

What Other Types of Sanders are there?

Sanders differ in size, the shape of the base, and how the sandpaper is fastened. There are models with triangular, rectangular, or square plates. As for fixing the sandpaper or other discs, you will find some with tweezers on the sides or velcro.

Here is a list of some other types of sanders you can find in the market:

  • Normal Orbital sander: It offers good finishes and is one of the most economical alternatives. Ideal for DIY fans.
  • Multi-sander: This equipment covers all previous models. It is a type of modern tool, a pioneer in DIY. It can be used as an orbital and rotorbital sander for sanding in corners or moldings by attaching an adapter. You just have to change the sander surface. It is ideal for hard work and irregular surfaces.
  • Mouse Sander: Mouse sanders are all small size sanders. This is the name of the equipment that fits in the palm of the hand. They are powerful and are used to perform jobs in hard-to-reach places. The sandpaper is fixed by self-adhesive and usually has many accessories.

Things to Consider When Buying Random Orbital Sander?

According to many users’ experience, good random orbital sanders have these characteristics:

Aspiration of Dust

Sanding produces a lot of fine sawdust. If it is allowed to float in the carpentry shop or at home, fine dust can cause respiratory diseases. It also makes your workshop or house challenging to clean. Investing in an electric sander with high-quality dust collection eliminates these problems and is highly recommended.

Dust-protected body

The dust created by electric orbital sanders is as harmful to the tool as it is to the user. The fine dust that passes through the tool body can damage the electric motor and bearings. It can also ruin the switching mechanism to turn the sander on or off. To keep your machine for a long time, buy an electric orbital sander that protects its internal parts from dust.

Multi-Grip

Most random orbital sanders offer only a one-handed grip, some models offer a two-handed grip, and some of them offer both. The two-handed grip improves control but creates accessibility problems. The one-handed handle allows you to sand hard-to-reach areas but gives you less control. The best way is to get a tool that allows you to switch between the two handles easily.

Variable speed

This is an important feature. If you plan to buy an electric orbital sander, it must be a variable speed sander. The variable speed allows you to decrease the orbits per minute (OPM) for fine sanding and increase the OPM for rapid material removal. You can achieve the same effect with a single-speed sander by changing the grain of the sanding pad. But why do things the hard way when there is an affordable alternative?

What Factors Should I Avoid?

Now that we have covered the factors to consider, it is essential to review some factors you should avoid when buying an orbital sander:

Vibration

Although the sanding pad of an electric random orbital sander is supposed to vibrate and wobble, a well-made machine transfers very little of that vibration to the user. High vibrations become particularly disconcerting for long periods. The best way to measure the extent of vibration is to visit a workshop where you can test several machines yourself. If you can not go to any workshop, it is best to rely on customer feedback.

Engines Prone to Failure

Even the best brands are not immune to this possibility. However, the probability of engine failure increases among lesser-known brands. The engine is the best place for manufacturers to make it cheaper. Therefore, be careful with low-cost products of unknown brands.

Low power electric motor

Manufacturers express the motor power of an electric orbital sander in amps. For light sanding, a sander from 2 to 2.5 A is sufficient. But, for medium to heavy sanding, you need a sander that has a capacity of 3 A or more. Do not worry too much about orbits per minute (OPM): Although it is an indicator of the efficiency of sanding, In itself, a high OPM does not mean a lot. A high OPM in a low power motor is useless. Yes, it will spin quickly, but it won’t have much sanding power.

Low-quality hook and loop

The quality of the hook & loop system, or lack thereof, bothers the users. The hook and loop system allows you to fix the sanding pad to the sander. It works exactly the same as Velcro. Before buying your sander, take note of how often people complain about rebel pads.

Final Thoughts

There are a lot of random orbital sanders available on Amazon, let alone the other types of sanders as well. Therefore, it can be a challenging decision to choose which one is the best for your purposes. The good thing with these tools is that you can get one at a low price if you want to try one out without all of the more advanced features. Otherwise, you can spend a bit more and find out some advanced features on it.

Our choice for the best random orbital sander is the Makita BO5041K. It’s one of the more expensive ones. However, it’s worth it. For the price, you get a series of features that let it adapt to whatever project you are working on with ease. It’s comfortable to use and leaves very little mess around your work area.

If you are looking for a budget choice or an entry-level sander, the Black & Decker BDERO100 will be a good pick.
