DA Sander Vs Random Orbital Sander – Differences

A sander is a tool that you can’t imagine to finish your job without it. There are many types of sanders to do different kinds of sanding. Here, we’ll talk about DA sander vs Random orbital sander, and these two are two common sanders in the community.

That’s why a dual-action sander vs. random orbital sander comparison comes to our mind. With not much knowledge of sanding, we become eager to know which one is the best. But we need to understand that you can’t fall all types of sanding in one category.

That’s why there are different sanders for different jobs, and every tool has its merits and demerits. So, let’s get started with a little bit introduction of both sander types and try to know their differences bearing in mind that different use cases make a tool good or bad.

Comparison Table:

What is a Dual Action Sander?

You might be familiar with a belt sander or a disc sander. Both belt sanders and disk sanders have advantages and disadvantages. To get the advantages of both sanders, we need something hybrid called a dual-action sander. The motion of this device can be guessed from its name.

The dual action means it has two motions. One of those includes continuous moving of forward and backward, and another one includes a little bit of rotary motion. That’s how you get both the motions and advantages of a belt sander and a disc sander.

Pros:

• moving forward and backward
• Air Powered or Electric
• includes some rotary motion
• DA Sanders is designed to produce fine finishes on different materials such as metal, fiberglass, wood, and more

What is a Random Orbital Sander?

Orbital sanders are fundamental tools for sanding. People use it in different projects because of its ease of use. You can sand corners and use any sanding paper to do the sanding. But this is not a powerful tool to remove much material.

That’s where random orbital sander comes into action. Random orbital sanders are the best to remove a lot of materials quickly and don’t leave sanding marks. It has a disk-shaped sanding pad that spins as well as rotates in a tiny circular path. It’s like the motion of the earth. However, keep in mind that its path is not uniform and gives you a random oscillation.

Differences Between a DA Sander vs Random Orbital Sander:

Though DA sanders and RO sanders are great sanders and sands without leaving a mark, there are a few differences between them. We found out that the handle size, operability, sanding path, aggressiveness, and use cases are the main differences. Let’s get into the details of random orbital vs dual action sander.

Handle Size

Generally, the DA sanders come with palm-sized handles, and the RO sanders come with large handles. But the opposite can be true for different models.

The difference can be seen for general handle sizes. With different handle sizes, it can affect your operability. Let’s talk about that in the next point.

Operability

Operability is an important issue when it comes to sanding. Depending on your skill and tool handling capability, the quality of the sanding is dependable.

For some jobs, palm-sized tools seem a good option for better control. On the other hand, sometimes, large handles can serve you better for fine finishing. More details fall on the use-case point that you’ll find scrolling down.

Sanding Path

This is a point to see a clear difference between a DA sander and an RO sander. The sanding path of a DA sander is defined. It means that the path follows a pattern, and it passes the same route over and over again. But the RO sander doesn’t cross the same path. That’s why its name is random orbital.

For RO sanders, you’ll see the random motions and a path like the earth’s orbital movement.

Aggressiveness

Aggressiveness indicates how much material a sander can remove in a short time. For different jobs, the requirement for the level of aggressiveness is different. Here in our Random Orbital vs DA Sanders debate, DA Sanders are more aggressive than the other one.

To cover large areas and have sanding capability for multiple layers, dual-action sanders are your only option. But for other light-finishing jobs and cover corners more effectively, random orbital sanders will be your best friends.

Overall Finish

The overall sanding finish is different for a DA sander and an RO sander. Just above the sanding pad, the DA sander features a weight that can be locked or unlocked. In locked mode, you get to remove more material much more quickly. This is not a feature of a random orbital sander. So, you’ll see a difference in the performance of these two sander types.

Use Cases

Both sander types have more aggressive and less aggressive features. However, due to their motion differences, they are used in different fields. A random orbital sander is preferred for works that include sanding the wood stock. It also is used for big jobs like wooden floors.

However, dual-action sanders are preferred in auto body repair jobs. It’s because they don’t leave any scratch marks and can be controlled more precisely.

Final Verdict

After knowing all about DA sander vs. random orbital, we can tell both are powerful tools and are perfect for separate use cases. But dual-action sanders are indeed more powerful and aggressive than random orbital sanders. Both have speed controls so that you can get your desired finish. In the end, we recommend the dual-action sander for its precise handling capability, versatile usability, and scratch-free sanding feature. Choose the best one that fits the most for your situation and has the finest finish.
