Understanding the Difference Between Rotary and Random Orbital Polishers is Crucial

When going about daily work in vehicle body repair, it is essential to use the right tools to achieve a perfect finish. Understanding the difference between Rotary and Random Orbital Polishers and when to use each crucial.

So What is a Rotary Polisher?

The head of a rotary polisher rotates in a fixed circle. This simple movement allows for a more aggressive and therefore faster cut - this is a rotary polisher’s greatest advantage. Speeding through multiple vehicles in a day with a higher level of correction and cutting.

A rotary polisher is mainly applied to paint correction as they are perfect for removing deep scratches and defects. They are therefore perfect for vehicle restoration, where the paint may be highly deteriorated.

So What is a Random Orbital Polisher?

A random orbital polisher moves in a random-orbit action, which means it spins in constant irregular overlapping circles to create an even and consistent finish. As the polisher head rotates, it moves in small circles which therefore eliminate any holograms.

Random orbital polisher operate in a reduced speed making ideal for beginners as they are easier to control and lesslikely to scuff or burn the paint.

So Which Polisher Should I Choose?

Both the Rotary and Random Orbital Polishers have their place in a bodyshop.

If you are looking for a precise finish, without holograms, then the Random Orbital Polisher is the tool to choose. It is often used to strip back old wax or polish before applying a new showroom finish.

The rotary polisher is ideal for removing larger defects. When paired with the correct cutting compound, it can make short work of even the most difficult paint corrections. It is normally used prior to final paint application.
