Dual Action sander also called DA sander is a tool that allows the operator to use their ability to get rid of surface defects and get consistent finishes.
The term dual-action implies that the da sander can operate in two motions, the first motion is moving forward and backward, and the second one is moving in an orbital motion.

Things to Consider before Buying a Dual Action Sander
We rounded up affordable and best dual action sanders in the market, so you can pick one without any hassle. But if you know what exactly to look for, you can make a more informed decision.
Type
The first thing you should consider is the type of sander you want. This part is important, and most DA sander reviews will tell you to consider the type you get first.
We listed two types – electric and pneumatic da sanders. If you want to get a sander for household or DIY tasks, an electric da sander will get the job done. But you need to be tied to a constant electric source.
Pneumatic dual action sanders are great for more professional-level jobs. Auto shops and other heavy users can use a pneumatic da sander to its full potential.
Pad Size
Then there is the pad size or the orbit diameter. A large pad size is great for working with larger surfaces. It makes quick work of them when smoothing or sanding.
But keep in mind that the larger the pad size, the tougher it will be working corners. 6 inches is a good middle-ground for most people.
Power
If your da sander lacks enough power you will end up regretting the purchase. It will practically become a useless paperweight.
While the power and speed will depend on the type of projects you want to take on, at least 10,000 RPM should be the minimum.
Ease of Use
Unless you want your hands to be very tired just after a couple of minutes of use, it’s always a good idea to get a da sander that’s comfortable and easy to use.
Look for power regulators that let you control the speed easily and a rubberized grip. Also, a lightweight sander doesn’t hurt either.
Low Vibrations
Speaking of comfort and not getting tired quickly, a sander with some way of dealing with vibrations will allow you to work for longer periods of time.
An insulated motor or any kind of low vibration feature is the best in this case.
Durability
The last thing you want is your dual-action sander to kick the bucket just after a couple of weeks of use. To avoid this, get one that’s built well and has durable components and quality ball bearings. Look for metal construction.
Price and Brand
Lastly, you have the price and brand. Settling on a price point is just a matter of deciding your budget and picking one that fits in that budget. But do keep in mind the previous features we mentioned.
As for the brand, all the ones we have reviewed here are reputed brand names and make great quality products.
You can pick one that works for you and call it a day.
What is a Dual Action Sander?
You have probably noticed that in some places, we referred to these sanders as DA sanders. DA is the abbreviated form of Dual Action. It essentially means that it has two motions.
One motion is where it moves backward and forward continuously, and the other is a rotary motion.
This motion helps you get the best results when it comes to smoothing, sanding, or buffing.
You can use it on different surfaces like wood or metal. Even auto shops also use DA sanders to give the cars a nice and professional-looking polish.
High-quality DA sanders won’t give you that swirl effect either. So, that’s another benefit.
How to Use a Dual Action Sander
Tools you will require to work with a dual-action sander
- A dual-action sander machine
- Source of power
- Sandpaper
- Sandpaper discs
- Dry cloth
- Finish or primer
Step 1: Pick your paper
take your time to decide on what type of sandpaper is good for you. For starters, you can start with a coarse grit with fewer sand particles per square centimeters as you work towards finer sandpapers.
To arrive at this decision, you will analyze the condition and type of surface you want to work on.
For a rough material surface, a rough 60 grit paper will do the work. Then switch up to a medium grit or fine grit, depending on the level of smoothness you are aiming at.
Consequently, if your surface is in good shape and you seek a smoother detail, then there is no need to go through the hustle. Just get a fine paper with 200 grit, and it will do the magic.
Step 2: Measure and attach your sanding disc.
Once you are settled on the grit, please measure the size of your sander. Then select the correct size of paper to attach to it.
All sanding discs come with a self-stick adhesive on the back which means you can easily stick or remove them.
If one disc wears out or completes its purpose, make sure it is removed because it is not advisable to use one disk on top of another.
Step 3: Clean your working surface
cleaning surfaces is an essential procedure when carrying out any task involving surfaces. This process is suitable for the sander and your safety.
Using your dual-action sander on a dirty surface may develop scratches or dirt marks on your surface. It may also cause wear to the surface of the sandpaper.
To check for dirt, you can directly look at the surface and see what is wrong. You may also need to run your palms across the surface and feel for any bumpy obstacles or indentations.
It would be best if you then got a wet cloth to wipe off any removable dirt.
You will have to obtain a container filled with water, a scrubbing tool, and some detergent for tough stains. Wash thoroughly until the surface remains clean, then allow to dry.
Step 3: Wear safety gear
The sanding process involves a lot of debris production, and some of these particles are harmful when they come into contact with your eyes, nose, and mouth.
You will need a mask, a pair of goggles, an apron or overall, and a pair of gloves. Also, make sure your feet are protected by wearing heavy shoes.
Some of these particles may cause terminal damage to your body if you use this machine in your day-to-day activities. Especially inhaled dust particles or paint particles that make their way into your throat then end up in your lungs.
Step 4: Restrict the area that needs sanding
You could be sanding a whole piece of wood or just a particular spot that needs to be leveled.
In many cases, it is vital to have boundaries on the exact location that you will need to work on to avoid sanding into other segments that may increase your workload.
Step 5: Start sanding.
Select the material you want to sand and follow the provided marks to know the exact points required to be worked on.
Ensure that your machine is well set up and the pad is in perfect position following the arrow directions provided at the back. Start your device at a moderately high speed, then place it vertically on the surface.
Move along in a forward and backward motion or a circular motion depending on the type of surface and level of smoothness you want to achieve. Make sure your strokes are evenly distributed.
You may also want to adjust your speed appropriately; If you notice that the surface is too hard for the sander to go through, you can try higher rates.
If the results are still similar, you can replace the sanding disk and use a coarse one to penetrate easily. Once your surface has taken shape, stop the machine to avoid damages or scratch marks.
Step 6: Finishing touches
Turn off your sanding machine and replace the sandpaper, this time aiming for a finer grit as required for fine finishing.
Turn on the device and proceed with sanding until you are satisfied with the work done.
Wipe off excess dust particles using a dry piece of clothing to confirm whether the result is satisfactory.
If you are okay with the appearance of the wood, you can use an excellent finish to protect against dust and weathering. You also can use wood varnish and wood oils if you want the wood to be exposed.
Essential Tips to Remember When Using a Sander
- Start the sander on the work surface to avoid the machine digging into the work surface.
- Stop off to prevent the machine from sliding across the surface, causing wild scratches, allowing you complete control.
- Please do not place the machine at an angle because it will cause hard to remove gouges.
- Avoid placing excessive pressure that interferes with the consistency of the finish.
- Use the correct size of the grit. Low-number grits are suitable for wood, plastic, paint, and many more. Grits above 100 are ideal for breaking edges and significant repairs.
- Maintain your sander by using an automated lubricator that applies equal amounts of oil in different environments.
FAQs
1. Why is an Orbital Sander Called a DA Sander?
The reason an orbital sander is called a DA sander is because of the two motions it uses for sanding.
These sanders will move forward and backward continuously. And also have some kind of rotary motion. These two motions work in tandem to give you the best results possible.
2. Can you Buff with an Orbital Sander?
You most definitely can. DA sanders can be used to buff paint and not just that. The finish you get is also pretty good. One of the best things about it is they are easy to use.
So, if there is a DIY project you want to take on which involves some buffing or polishing, you can rely on a high-quality dual-action sander to get the job done.
3. What is the difference between a Sander and a Polisher?
The main difference is the spin speed. A controlled speed is good for protecting the paint finish. Being too aggressive can cause the paint to come off, especially around the edges.
But that doesn’t mean you can’t polish with a sander. Some DA sanders will have regulators that allow you to control the speed. Those can be used to polish paint as well.
4. When do you know that you Should Replace your Sanding Pad?
No matter how high-quality your sander is, you will inevitably need to replace the pad. There are some telltale signs you can keep an eye out for to know when is the right time to replace it.
One of the most common ones is when the sanding pad slips from the center. In other words, it isn’t aligned correctly anymore.
When this happens, you will feel it grab onto the surface or the project you’re working on.
And if you notice that there is a lack of consistency, then it’s probably due to a change.
You will see that the grit isn’t there anymore. Lastly, you can check for worn-out spots on the pad.
Continuing to use a worn-out pad is a bad idea and is simply isn’t worth it. There is a risk of ruining your project. So, make sure you replace it when needed.
Conclusion
Whether you had used a Dual Action sander before or tried another type of sander, you need to understand that the procedures are not much other than how you would operate a machine of the same kind.
Every step provided is necessary to ensure you get the best results.
So, which one is the best dual action sander? If you want a hassle-free experience and a sander with adequate power, durability and that is also easy to use, you can’t go wrong with the TCP Global Heavy Duty 6″ DA Palm Sander.
It’s a straightforward tool that checks all the boxes.
