What Are the Differences Between Dual Action and Random Orbital?
The main difference between dual action and random orbital is that random orbital is the ideal option for waxing while forced rotation dual action is better suited for polishing.They are both easy to use but have different mechanisms that power their polishing.
To understand the differences better, you need to know the meaning of certain terms, and this includes the following:
- Orbital – an elliptical movement around a point
- Dual action – combines rotational and orbital movement
- Rotational – circular movement around a point
- Forced rotation – maintains movement irrespective of applied force
- Random – moves following an irregular pattern
With that being said, let us go deeper to fully understand the differences between the two car polishers.
The terms random sander and dual action are used interchangeably when describing the two polishers. The main thing to note is that they both have orbital and rotating movements, which makes them dual actions. However, it’s worth noting that the rotation pattern, forced rotation feature, and power create some differences in their application.
– Motion and Speed
One of the differences between both polishers is that the speed of rotation of random orbital polishers is between 1,800RPM and 7,000RPM. With a dual-action polisher, it’s a lot different, as it operates at a speed of 1,500RPM to 6,800RPM. Also, the momentum created by the speed is a major driving force for the operation of the random orbital polisher.
The motion of dual polishers is a circular motion, while the motion for the random polisher is a random motion, as the name suggests. Dual action polisher combines rotational and orbital movement.
When using a car buffer, it’s important to know the right speed to use and ensure that the RPMs you use are within moderate levels, which are not too low or too high. The ideal speed ranges are between 2000RPM to 2500RPM. However, as you complete the process, it’s important to lower the speed to 1100RPM.
The key thing to always remember is that even with the right polisher, you can ruin everything if you don’t use the right buffing speed.
– Functions and Features
Dual action polishers are also known as DA polishers, and it combines two functions, especially in terms of their motion. The DA polisher is user-friendly, and you can rest assured that it will not damage the paint. It’s a good option for anyone who wants to enhance the appearance of scratches.
On the other hand, random orbital polishers feature dual mode, and this makes it the preferred option for different polishing tasks. The key features it has are waxing applications, buffing, and polishing.
– Price
Another distinction between the two polishers is their price. There are so many types of random polishers on the market, and they are all available at different prices.
This also applies to dual polishers, as there are different types, and they are all available at different prices. In general, dual polishers are generally more affordable than random polishers.
– Difference in Uses
Even though both random orbital sanders and dual action sanders have the potential to sand or polish materials, it’s important to note that there are a few differences in how they are used. The main difference between how the two are used lies in the rotating path that leads to the end result. If the desired end result is a smooth surface prepared for staining, painting, or varnishing, you’ll need to sand the surface.
Are buffers and polishers different? You might want to think they are the same, but they are completely different. Buffers are designed to improve or modify the appearance of car paint. They are mostly used with waxing compounds. Polishers, on the other hand, are designed for use in cleaning out imperfections and car scratches.
– Differences in Ergonomics
Another difference between dual action and random orbital sanders is in their ergonomics. DA sanders usually have a small grip thanks to their smaller designs. They are the perfect option for people looking for more control.
On the other hand, random orbital sanders feature a larger grip, which is still comfortable to hold. The next question you may ask is “What is the best polisher size?” The best option to start with is polishers with a 6-inch pad. This is because they provide sufficient surface for effective polishing, even at smaller areas and curves.
– Better Option
The dual polisher is the better option to consider, but it’s important to note that a rotary polisher is also a great option for cutting paint quickly. Also, the rotary polisher is lighter and makes it possible for the user to apply less force, thereby reducing cutting power and heat.
Despite that, dual polishers are still considered the best because they remove scratches evenly without leaving swirl marks. Dual polishers are not only better than rotary polishers, but they are also better than random polishers as well. This is also because they do a better job of removing coat layers effectively.
What Are the Dual Action Polisher Characteristics and Specifications?
The forced rotation dual action orbital polisher characteristics and specifications include combining orbitals and rotary motion to create a forced action. This is different from the other polishers in that this one drives both the orbiting and the rotating motion.
With that being said, the polisher is able to deliver a more consistent pattern. Another thing worth noting is that it’s easy to use them as a random orbit. However, this is a bit dangerous because of the fast heat buildup that is common with this type of polisher.
– Dual Action Buffer
This is a type of orbital buffer that shares some similarities to the random orbital dual action buffer.
However, it lacks random buffer pad movement. Another thing worth noting is that it’s safer and more versatile to use, unlike other rotary polishers.
– Best Dual Action Polishers Available
There are many dual polishers on the market today, and choosing the best can be tricky.
However, Makita and Rupes are among the best dual polishers that you’ll find today.
They are professional-grade polishers made by the best manufacturers.
– Pros and Cons
The main advantage is that it is a safer option, especially for beginners, but they are stronger than random orbit polishers.
However, the fixed backing plate offers limited options, and polishing abilities are limited by fixed rotation.
– Dual-Action Polisher vs Sander
Polishers and sanders share some basic principles, but it’s important to note that they are not interchangeable, especially when it comes to how they are used and their design.
In many cases, the size and shape of dual-action sanders do not make them suitable for use as polishers. Also, the lack of features to enhance the removal of particles on polishers doesn’t make them a great alternative for sanding.
– Safety
Dual polishers are safe, but only when you are using the right pads and chemicals.
With that, you won’t have to worry about it creating unnecessary swirl marks, even if it is your first time handling the dual polishers.
However, it takes practice to become a master of the art of polishing and buffing.
What Are Random Orbital Polishers Characteristics and Specifications?
The random orbital polishers characteristics and specifications include combining standard and rotary orbit polishers. They use the momentum from high-speed orbital motion to create rotational motion.
Random polishers are also safe for beginners and are known to be very easy to use. This type of polisher creates a random pattern resulting from a combination of pad grip, speed, pad size, and stroke length.
– Random Orbital Buffer
This is a type of dual polisher as they share similarities in their design. Basically, the spindle and motor are 90 degrees from the pad and buffing plate.
They also share similarities with the fixed orbital polishers, as the axis of the buffing plate and that of the spindle are offset. The main advantage of these types of rotary buffers is that they are versatile and affordable.
– Best Random Polisher Kits Available
One of the best random polishers you’ll find on the market is Chemical Guys TORQX random polisher.
It is a great option for the applications of wax and other light applications on the exterior surface of the vehicle.
Another amazing option is the Rupes Big Foot, which is also a professional-grade random polisher.
– Pros and Cons
The main advantage of the random polisher is that it’s a great option for beginners who want to learn.
Also, it’s easy to use and handle, and the polishers are affordable.
However, they are not as strong as rotary polishers and forced rotation polishers.
Conclusion
There are many differences between dual action and random orbital, but we have highlighted these differences in this dual action vs random orbital comparison. The best option to choose depends on your preference, but it’s worth noting that dual-action polishers are the better option when it comes to polishing.
On the other hand, the best option for beginners is the random orbital polisher. This is also an ideal option to use if you want to sand off your vehicle’s paint and apply a new one. The option you choose completely depends on your preference and whether you are a beginner or a professional.
