How Does A Random Orbital Sander Works?

A random orbital sander works on the circular motion. It is the central norm of this tool. Most sanding tools only require driving over the surfaces by following the norms straightforwardly. With the help of sandpaper grit, you can give an extra finish to your project. Using a random orbital sander will allow you to polish any hard floors swiftly.

This tool has three heavy functions: a metallic head, around wheel bearing, and sandpaper wear. Most of the tools have a composed ball-bearing mechanism that will fix a sanding round pad. This ball bearing works to rotate the wheel inside the machine to run the pad. The overall mechanism of this tool is compared to any running wheel of the vehicle.

With the persistence of smooth sandpaper, you will get the chance to use this tool as a polisher. This tool can reduce old paints and shabby stains within a second. The adjusted pad with the random orbital sander polisher works great for furnishing the back-to-back projects. The tool can encounter the hard points with tiny sharp pads very keenly. Along with these, it will penetrate the surfaces very deeply and work little by little with small orbits.

How to Use An Orbital Sander?

To use an orbital sander, you need to follow some indicated instructions. Being a novice, it is customary to get confused about how to use a random orbital sander. As we have already mentioned, how does a random orbital sander work? Hope you will hint about how a random orbital sander body works.

Don’t worry too much about this; the overall process is straightforward. Let us see how a random orbital sander works and uses it.

Step 1-Prepare The Materials Before The Task

No matter what, top-rated random orbital sander you’re using for your projects. Without good preparation, you can’t tackle the whole procedure to complete enormously. Try to collect all the necessary information you need to do the job. Likewise,

  • Wrench
  • Hand gloves
  • Sandpaper 60-80 grits
  • Random orbital sander
  • An unpolished surface

Choose a particular area where you can work comfortably. Then move on to the next step.

Step 2- Apply Sufficient Pressure to Drive It Properly

Many people think that driving the orbital sander may require some extra push. But what they think is the opposite in reality. This machine is very likely to work with the weight of the machine. You just need to focus on the work, not even what pressure it will provide you at a time.

Orbital sanders only prefer the weight which comes from you to hold it appropriately. Find out your focus point, then hold it and avoid giving extra pressure. Otherwise, you could even break the electric hand sand as well as damage the surface of the pieces.

Step 3-Set The Sandpaper & Drive The Tool over The Surface of The Pieces

Finally, set the sandpaper inside the tool. Drive it over the surface. Remember to put the sandpaper equal over the surfaces. Keep your hand straight and follow the circulation keenly. It will help you to avoid any unevenness.

10 Tips for Mastering The Random Orbit Sander


Before going to orbit on any rough and rugged surfaces, you should know some particular things. Otherwise, there is a slight chance to get swirl scratches from driving the sander ignorantly. This is why we have attached 10 crucial tips for mastering this tool. Just check them out at a glance.

Tip 1- Take A Clear Conception to Run The Sander

Almost every orbital sander runs with some specific norms and ways. You should maintain the rules correctly. Most importantly, the pad attached to the sander will move in two ways. First, this orbital pad will wiggle too tightly while taking a curve. Secondly, it will run very swiftly and by frequent movements, including overlapping, inscribing, etc. This suggests you should learn how to run an orbital sander with random orbital polishing pads.

Tip 2- Try to Run It Slow

When you’re new to running the sander, do not try to drive it rapidly. Hence, the sander will habitually run very steadfast to withstand the even finish.

Tip 3- Don’t Pressurize The Sander

Hold the tool and go slow to get your expected finish. Some mini random orbital sander will usually be too worthy of beating the tiny edges so nicely. While you give enough pressure over the tool, it will slow down the speed of the sander. Sometimes, it was the reason to slow or stop the pad rotation. So do not press down the sander crazily. Let it do the task on its own.

Tip 4- Place The Sander Properly

Place the sander appropriately before turning it on. If you hurry to finish the task, there is a high chance that the sander will deeply put scratch marks over the surfaces. That’s why take a break in the middle of the work or just before starting it again. It will help you to get proficiency in running this rotating beast.

Tip 5- Use The Overlapping Passes to Sand The Large

At the beginning of sanding, any large surface may seem more difficult for anyone. So try to use the sander by maintaining the rules of overlapping passes. Keep 50 percent density before taking every pass.

Tip 6- Do Finish The Task with Hand Sander

After finishing the primary sanding, give a final touch of your hands. It will give a professional vibe, and you will recognize the difference between the two sandings.

Tip 7-Vac The Area After Every Successful Bite

Clean off the sanding area with the vacuum cleaner. Use it instead of the fan inside the sander. The vacuum sander will contribute to keeping the area clean and tidy. It also prepares the area to go for the next bite.

Tip 8- Hold The Sander Around Its Neck to Avoid Tipping

Tipping is a crucial fact in the field of sanding. It isn’t charming, especially on narrow surfaces. Hold the sander around its neck to get a gorgeous finish to avoid such issues.

Tip 9- to Avoid Inconsistent Finish Sand Twice Instead of Fast

Do not try to drive the sander too fast. You can stop the sander after finishing the first stroke. Then prepare the sander again to get better results and better practices. To run it quickly may lead to the surface’s unexpected scratches and inconsistent finish.

Tip 10- Invest Handsome Amount to Buy Discs

We usually invest more to buy some top random orbital sander. But I didn’t think to buy a high-quality random disc that would center around the entire project. A good quality disc will provide you with a uniform size, which is unexpected for any cheap rated discs. On the other hand, investing more in buying a disc will save you from changing the sander in the future. Click to get updated about what is the best random orbital sander recently?

  • Go as much light as you can. The more lightly you grasp the tool, the more evenly you’ll get as an output.
  • Keep the sander air pressure about 90 psi to run it optimally.
  • Check the RPM of your sander once a month. As most of them will run over 12,000-10,000 RPM, this ratio will decrease randomly when it gets aged.
  • Oiling the sander regularly to get better performance.
