Variable speed random orbit polisher

Types of Variable Speed Random Orbit Polishers

A variable speed random orbit polisher is an electric tool used to polish and buff surfaces, especially in automotive detailing. The polisher combines rotary and orbital movements, allowing it to cover surfaces evenly. The variable speed feature allows the operator to adjust the speed of the pads to suit different tasks and surfaces. This ensures more control and reduces the risk of damaging delicate surfaces or paints.

Generally, there are two main types of variable speed random orbit polishers.

• Dual Action Polishers

  This is perhaps the most common type of variable speed random orbit polisher. The tool gets its name from the dual action it offers–orbital and rotary. The pad on the polisher moves in a circular motion while also orbiting around the center. This action allows it to polish surfaces effectively without causing any damage. The DA polisher boasts a variable speed trigger, allowing the operator to adjust the speed with ease.

• Circular Polishers

  These are other types of variable speed random orbit polishers. Unlike DA polishers, circular polishers only have rotary motion. The polishing pad moves in a circular motion without any orbital action. Because of the lack of orbital movement, circular polishers are more aggressive compared to their dual action counterparts. While this can be beneficial when working on stubborn paint defects, it also means there is a higher risk of damaging the paint if one isn't careful. Just like the DA polishers, circular polishers also come with variable speed settings.
