Best Random Orbital Sander

The Best Random Orbital Sander 2021 For DIY Project

When it comes to woodworking, you need a lot of tools to get the job done right the first time. However, one could argue that the most important part of everything comes at the end when you’re finishing the piece. The reason for this is that if you don’t sand it down and make it smooth, then the finished product could be dangerous to hold. As such, it’s imperative that you have the right sander to make your piece as polished and professional as possible.

While there are a few different kinds of finishing sanders out there, none are quite as versatile or reliable as a random orbital sander. These handheld devices make it easy to work in tighter spaces while also leaving a better finish than other models.

Today we’ll go over the core components of these sanders as well as show you some of the best options out there. Whether you’re a professional or a DIYer, these sanders are sure to take your wood projects to the next level. You can also read our selected top sander for trim work.

What is a Random Orbital Sander?

This machine is designed to work on pieces that need a smooth surface without any scuff marks. Some sanders will leave trails of where they’ve been, but not random orbital ones. The secret is in the oscillation of the pad, which ensures that you don’t have to worry about circular grooves in your finished piece.

Typically speaking, these sanders are used for polishing finished pieces to make sure that there are no splinters or rough edges. As such, they are mostly compact devices that can fit into tighter corners and allow you to work on many different surfaces.

Nonetheless, due to their power and versatility, they work well as a removal device or a finishing piece, making them a must-have for any serious woodworkers.

Difference between Orbital Sanders and Random Orbital Sanders

Yes, the names are fairly similar; orbital sanders and random orbital sanders, even though both are used for sanding, there exist significant differences in their attributes and functionality.

The first major distinction is their movement, orbital sanders move only in a single circular direction while random orbital sanders as implied by the name, move in random oscillatory motion and hence prevent marks and swirls that are inevitable in other sanders.

This means that the best random orbital sander runs two operations simultaneously, the operation of the traditional sander, it moves in a circular motion like the traditional orbital sander, and at the same time, its circular pad rotates along the main axis, causing a complete random motion. This random motion is important for reducing marks and produce a smoother surface.

Another difference is in the shape of these two machines, random orbital sander has a rounded base which enables its round sanding pad to oscillate and spin around for effectual sanding. Orbital sander, on the other hand, has a square base that allows its square sanding pad to get into tight corners with ease. Check our selected another sander for stairs in 2021.

It is a universal truth that the operations of random orbital sanders are more user-friendly, versatile, and comfortable when compared to traditional orbital sanders. Who wants stress and trouble?

What we like most about this sander is the dust collection system. While most models have a dust bag and port, this particular unit comes with a reusable filter as well. This ensures that the air stays cleaner while you work. Unfortunately, if you connect it to a shop vacuum then the filter doesn’t work, but if you don’t need that much collection space, you could potentially operate without a mask.

The other features that we like about this sander include a soft starting system that ensures you don’t accidentally gouge your work, an ergonomic soft-grip handle to reduce vibration and fatigue, and a carrying case so that you can keep everything together and organized.

As such, we love this variable speed random orbital sander for what it can do with wood and how well it can handle any project we throw at it.

Overall, this is a great piece for anyone who does a lot of woodworking and needs something that can keep up.

The most significant aspect of this sander is the quality of the machinery and its performance. While other units have similar specs, this model is built to last and will take on almost any project with ease. To do that, it comes with a robust three-amp motor and a variable speed adjustment that enables you to work on a wider variety of pieces.

As far as dust collection goes, this model comes with a rather large bag, but it also has its own vacuum adapter so that you can connect to a shop vacuum if need be. While we do wish that it came with a filter as well, the results are still impressive, leaving very little debris while you work.

7. PORTER-CABLE 7346SP 6-Inch Random Orbit Sander with Polishing Pad

Best Random Orbital Sander

So far, we’ve seen random orbital sanders that were built with high speeds in mind so that they can work well as a finishing product or a removal sander.

However, that also means that they are not conducive to working on other materials such as cars or metal. The reason for that is because higher speeds can create much more friction, thus overheating any metallic pieces or buffing paint off a car door.

Thus, if you want something that can work on a variety of materials besides wood, this is the sander for you. It has a much more robust motor (4.5 amps instead of three), and it operates at up to 6,800 OPM. As you can see, that is even lower than some of the other sanders at their slowest speed. Again, the purpose behind that is so you don’t risk overheating metal or wearing down other materials too fast. High speeds are perfect for Parawood wood, and others, but not much else.

To further drive this point home, the Porter-Cable Sander also comes with a polishing pad as well as a standard sanding pad. Also, this measures six inches in diameter instead of the usual five, meaning that you can cover more area in less time. Overall, this is an efficient and versatile machine.

The other thing that we like about this sander is that it comes with an adjustable handle for stability. Since it’s heavier than other models (six pounds), you need the extra point of contact to ensure that you don’t lose control while you work. Best of all, it can install on either side so if you’re left or right-handed it doesn’t matter. Finally, it comes with a three-year warranty.

What We Like:

  • Powerful 4.5-amp motor
  • Variable speed adjustment
  • Operates between 2,500-6,800 OPM
  • Six-inch sanding and polishing pads
  • Side handle for better grip and control
  • The handle is movable from left to right
  • Ergonomic top grip
  • Full ball bearing construction lasts longer

What We Don’t Like:

  • No dust collection system
  • Heavier than other models
  • In rare cases, the shaft may break under pressure

8. SKIL 7492-02 5″ Random Orbital Sander – Most Safe to Operate

Best Random Orbital Sander

Whether you are a hobbyist that needs some finishing touches on a workshop piece, or you are a refurbished that’s handling a big home improvement task, the SKIL 7492-02 5-inch Random Orbital Sander could be your ultimate companion to a fine finish and smooth stock removal.

Although, not on the high end, this basic random orbit sander uses a 2.8 Ampere motor to drive up to 12,500 OPM fixed speed.

This little machine features a pad brake system which helps in minimizing scuffs to give a swirl-free finish while also eliminating gouging during operation. It comes with a pressure control indicator that notifies you when there is accurate or overpressure.

This machine comes with a micro-filtration system with the sealed switch to capture dust particles from dispersing into your environment and keeping your surface tidier. The dust canister has a transparent casing, hence, emptying its content is as easy as you see it.

What We Like:

  • Excellent dust collection
  • Entry-level price
  • Lightweight
  • Great build quality

What We Don’t Like:

  • Relatively low power
  • Not good for pros

After looking through these various sanders, we can safely say that our top two picks would either be the Makita or the DeWalt models. First of all, we like that they come with a whole kit and carrying system so that you can keep everything together.

Secondly, they have the best features and performance we’ve seen of any random orbital sander. Finally, these companies have a long history of making high-quality products, and we know that they are committed to bringing you the best tools possible regardless of your skill level or expertise.

How to Choose a Random Orbital Sander

For anyone, selecting the best random orbital sander is a function of goals and purposes. If you are well informed, picking one depends on your long or short-term goal. For the hobbyists, who only need occasional sanding and stock removal, a small machine with little frills should do, while heavy woodworkers like cabinet makers and carpenters will surely require a more powerful machine that can deliver great performance consistently for a long period of time.

Although the primary purpose of this kind of sander is to polish materials without leaving marks, that doesn’t mean that there aren’t plenty of different considerations that go into picking the best model for your work.

Overall, each one that we are going to look at comes with the same basic principle, but they do have some distinct variations that are important based on your needs. Here are the most important factors to consider when picking out the best random orbital sander.

The Base Plate

The part of your random orbital sander where sandpaper is attached is called the base plate. Generally, there are 3 major areas of concern about the base plate, if your sander is to live up to expectations.

The base plate of any random orbital sander determines the size of the sanding area, most random orbital sanders come in either 5 or 6 inches, any sander below 5 inches are known as finishing sanders while those above 6 inches are the pneumatic sander for industrial use.

Your next area of concern should be how the sanding disc attaches, some sanding discs are attached with adhesive, which is somewhat not reliable as there is every probability of wearing, hence, coming off while the machine is in use. Manufacturers of the latest sanders are moving towards the more reliable hook and loop system, it’s easier to do and durable and you might want to consider this over that.

Another thing you should watch out for is the base plate hole for dust removal, the majority of sanders on the market come with holes on the base plate, which helps in sucking up dust created by the machine. It’s better you go with a base plate of high quality or you will be coming back to the market in no time.

Power Source

The dependability, weight, and power of a random sander also depend on its power source, typically, there are three power sources for random orbital sandals; cordless (battery operated), corded, and pneumatic, each of which has advantages and disadvantages, but nowadays, there are sanders that are battery operated and corded at the same time.

Corded sanders are more powerful and more reliable because you need not worry about battery charge level, but you will have to cope with the cord getting in your way while working.

Cordless or battery-operated sanders won’t give you the cord headache, but you won’t get the power and reliability of corded sanders. Pneumatic sanders are professional machines and require air compressors to operate.

Whichever you prefer, there is a better option you might want to consider, nowadays, there are sanders that are battery operated and corded at the same time. But they come at a fairly high price

Size

When talking about the measurements for this type of sander, you want to look at the size of the unit itself as well as the width of the sanding pad. As far as the device goes, you want something that is lightweight and easy to carry so that you can work non-stop without getting fatigued or cramped in your hands.

If the sander is too big and cumbersome, then you will tire out faster, and you won’t be able to get into those small spaces.

You also need to pay attention to the size of the sanding pad as that will determine the level of detail you can have while working. Usually, handheld random orbital sanders come with circular pads, meaning that you want to focus on the diameter to see how much space you get.

Motor

The importance of the motor depends on how often you will be sanding with this machine. If you’re a casual DIY enthusiast, then something with a smaller engine will work just fine.

However, if you’re a professional who needs it to work on a near-constant basis, then you want a motor that can handle that kind of load. Usually, the motor will be classified by amps, with most sanders ranging between three to five. If you get a sander that is much below three, then it won’t be able to handle large jobs or frequent usage.

Speed

Because this is a finishing sander, you want something that is versatile so that you can use it for a variety of projects. As such, it’s usually best to get a model that comes with a variable speed adjustment. This allows you to go slower or faster depending on your needs, making the whole thing much more reliable.

As we mentioned above, these sanders can be ideal for both removal of material (such as paint or varnish) as well as polishing, so if you get a unit with adjustable speeds, then you can customize your experience as you see fit.

Grip

While the size of the sander is essential for limiting fatigue, the grip will be much more crucial as to your overall comfort. In some cases, it will be located directly over the motor so that you can get more control while you work, while in other situations it may have something sticking out on the side or front. Depending on the type of sanding you’ll be doing, you want to get a grip that will match your style so that you can keep working without having to readjust yourself constantly.

Dust Collection

Finally, whenever you’re sanding, you will create a huge mess of dirt and debris while you work. Thankfully, many of these units come with a dust collection part that enables you to keep your surfaces clean so that you don’t have to spend a lot of time cleaning up afterward.

Unfortunately, not all random orbital sanders have this feature, so you will have to decide if it’s something that you need (we highly recommend it). That being said, there are some things to consider when looking at a dust port.

First, check to see if it can be adapted to work with a shop vacuum. This will allow you to work much longer without having to change the bag as often. Second, see if it comes with a filter to remove finer particles from the air. This can help keep your lungs from breathing in dust and may even allow you to work without a mask.

Finally, check the size of the bag to see if it’s conducive to working long shifts. If the bag is small and it won’t connect to a vacuum, then you may have to limit how much you sand before changing it.

How to use this Random Orbital Sander?

Random orbital sanders are great for when you need to get the job done quickly. They are much faster than other types of hand sanders, and they have a lot more power too! How do you use one? Well that’s what this article is all about! We will take a look at how to set up your machine, how to position it correctly, and give some tips on which grits work best for different tasks.

Setting up the sander

When you get a new random orbital sander, it is usually pretty easy to set up and get started. Make sure that you are using an appropriate voltage for your model of machine (it should be written on the side or back somewhere), then match it with either 120 volts in North America or 220-240 volts in Europe. Once that is sorted out, you should plug it into the power and turn on your work light (if it has one).

Positioning

How do you hold a sander? Well there are two different positions for holding a random orbital sander – palm grip and fingertip control. When using a palm grip, put your hand on the side of the sander and use your whole palm to hold down and control it. With fingertip control, you put your fingers over the top to guide where it goes, using only a small amount of pressure from your fingertips for movement.

How do you know which one is right for you? Well most people tend to be more comfortable with a palm grip, but you should try out both to see which one feels best. How do you know where to position it? You want the sander flush against your work piece at about a 45 degree angle (it doesn’t have to be perfect). Then move slowly across the surface until all of that area is smooth.

Different Grits

How do you know which grit to get? Well it depends on what you are trying to accomplish. If your piece is already smooth, but needs a little extra shine (or if the finish has been worn away over time), then try out an ultra-fine paper like 600 or 800 for a great sheen. For removing paint and smoothing rough wood, you will want a grit of around 80-100. How do you know which paper to get? You can always check the recommended paper for your sander on its manual or label.

Frequently Asked Questions (FAQ’s)

How do you change the paper?

Usually, all that needs to be done is loosening a knob at the back of your sander and pulling out the old sheet. How do you know it’s ready for a new one? If there are any little pieces of sanding dust stuck in between the grooves on top then give it a good wipe down before putting on a new sheet. How do you replace the paper? It should be easy to fit it into place and then tighten down that knob back up again (don’t over-tighten).

​How can I get better results when using my sander?

Sand in long straight strokes as much as possible, but don’t forget to change the direction of your sander as you go.

How can I avoid scratching the finish?

Sand in a circular motion until you remove all of your marks and scratches.

Can I use a random orbital sander for shaping wood?

Yes, if shaping wood is just an occasional thing, any sander that has 3-amp motor power and above will do a great deal of shaping, however, if your primary purpose is wood shaping, you’d be better off with a dedicated machine for shaping.

What random orbital sander is good for drywall?

Although you can use one with variable speed, provided it’s one-off work, it’s not recommendable. A dedicated drywall sander is a tool for that.

What kind of sander is best?

Orbital sanders are the best type of sander for fine work.
Use your belt sander for larger projects.
A random orbital sander is one of the most effective electrical sanders.
Multi-Sanders can stand for a variety of Sanders.
Your Oscillating tool is an effective sanding tool, too.

Is an orbiter sander good for removing paint?

Ideal for removing paint in an orbital sander. This is a good thing in many ways because you don’t want the paint to peel off easily. But, when you want to rearrange a piece of furniture, this can be a problem. Using a paint stripper can be harmful to the surface you are working on.

Conclusion

By now, selecting the best random orbital sander for your project should come with no headache at all, whether you are a carpenter, homeowner, or hobbyist.

The performance, comfort-ability, quality, and reliability of your sander depend mostly on the factors above, so visit the market and make an informed decision by picking the perfect fit for your purpose.
