Dual Action polisher vs Rotary polisher

When it comes to choosing a machine polisher, one of the most frequent questions our customers ask us is: “What is the difference between a dual action (DA) polisher and a rotary polisher?” It is a particularly good question and for those just starting out with a machine polishing, the answer is important!

Now, both devices will do a great polish job but are there are differences that you need to keep in mind when choosing between the two.


A rotary polisher is a machine used to polish cars. It works amazingly fast and also requires its users to have a bit of knowledge and experience. It is most used by highly qualified and trained technicians.

This polisher has a high cutting speed which makes it a great option. Whereas a dual polisher takes more time to get the job done. Rotary polisher is a good choice when it comes to a high damaged surface to work on. Rotary Polishers will remove marks in paintwork that dual action polishers cannot.

Rotary polishers due have some disadvantaged like it will polish away the paint if proper care is not taken, it has no free rotation movement so this makes it impossible to stop it from moving.

Dual action polisher

A dual action polisher is another machine used to polish cars; it is a type of polisher that spins on an elliptical orbit which leads to heat distribution to a larger area making it safe for use. Spinning the polisher on a single spot will not burn your paint.

This polisher does not need any manual work to be done as it does all the work with the elliptical spinning. It also has slow RPM which lets it take more time to cut through scratches. Although it takes more time, the results obtained are usually great. This polisher is extremely easy and safer to use, it also stops rotating to avoid burning the paint if pressed hardly against the surface.
